LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. The goal of LASIK surgery is to reduce a person’s dependency on glasses and contacts and correct common problems such as farsightedness, nearsightedness and astigmatism.

The experienced doctors at Kaskaloglu Eye Hospital specialize in LASIK surgery.

What happens during LASIK surgery?

After a routine eye examination, you will be examined with a corneal topographer. Eye drops are then used to anesthetize the eye. During LASIK surgery, a laser device is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middle section of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced. The presence of a high speed eye-tracker on our system ensures accurate treatment even if you accidentally move your eye.

In our hospital we use the latest WaveLight ALLEGRETTO WAVE EyeQ Excimer Laser. The WaveLight ALLEGRETTO WAVE EyeQ Excimer Laser has a very fast eye tracker system that ensures accurate positioning of the laser beam on the corneal surface, thus enabling us to perform custom ablation, that is, laser treatment tailored just for you. Our surgeons also use the latest innovation in LASIK surgery, the Intralese FS-60. For more information on Intralase please visit www.intralase.com.

What kind of disorders can be corrected by LASIK?

LASIK can correct nearsightedness, farsightedness and astigmatism.

Who will perform my surgery at Kaskaloglu Eye Hospital?

Professor Mahmut Kaskaloglu, the hospital’s founder and one of the most respected eye surgeons in Turkey, and Dr. Bilgehan Sezgin perform all of the LASIK operations in our hospital. Prof. Kaskaloglu is a doctor with more than 34 years’ experience both practicing and teaching ophthalmology. Dr. Sezgin has worked at Kaskaloglu Eye Hospital since 2004.

How should I prepare for surgery?

The day before surgery, stop wearing any perfume, make-up, lotions or creams. You will come to the clinic at the appointed time wearing casual, comfortable clothes. The procedure takes only a half hour, but you should plan your day so that you can spend two to three hours at the clinic.

Is LASIK painful?

The procedure is relatively painless, however, some patients complain of a brief sense of pressure. A few hours after the procedure there may be temporary stinging, burning and tearing. In that case taking a painkiller should help.

When will my vision be normal after surgery?

Most patients will have very good vision the next morning. However, final healing will take a few months.

When can I go to work?

Depending on your occupation, you may start work in 1-2 days.

Will my health insurance or social security pay for the operation?

Generally speaking, they will not. However, some insurance companies may pay for special cases. You should consult your health care company.

Will my eye be covered after the operation and will I use any medication?

After the operation we will give you protective glasses to be worn that night. You will be asked you use drops for one month.

When should I remove my contact lenses?

You should remove soft lenses two weeks before surgery and hard lenses four weeks before surgery.

Will I need glasses after LASIK?

The majority of the patients can function without glasses after LASIK surgery. Patients over age 40 may need reading glasses or night driving glasses.

Can LASIK be performed on both eyes on the same session?

Yes, this is the standard procedure in our clinic.

What are the risks of LASIK?

There are a few risks associated with LASIK surgery. Some people have experienced blindness, vision changes, dry eyes, and a continued need for glasses after surgery. However, under the care of the experienced professionals at Kaskaloglu Eye Hospital and with a clear understanding of the risks and alternatives associated with LASIK surgery, you will most likely be quite happy with the result of your surgery.

Where can I get more information about LASIK?

INTRALASE

 

IntraLASIK is a form of refractive eye surgery that is similar to LASIK. It creates a corneal flap with a femtosecond laser microkeratome rather than with a mechanical microkeratome, which uses a blade. The difference between LASIK and IntraLASIK is the method by which the corneal flap is created. IntraLASIK can be used to surgically create monovision to improve your ability to see objects both near and far.

A LASIK flap created with a femtosecond laser is regarded by many ophthalmologists as an improvement over traditional LASIK because of a greater accuracy in flap size, shape, and thickness.

Kaskaloglu Eye Hospital uses the IntraLase FS60 Laser, which has a computer-controlled laser that creates the corneal flap for LASIK. This provides unprecedented control and the ability to customize the flap for each of our patients.

Creation of a corneal flap is
performed with a microkeratome

What is a femtosecond Laser?

A femtosecond laser is an infrared laser that can treat tissue very precisely with significantly less heat created than other laser treatments , a big advantage in eye laser surgery. Femtosecond lasers work with ultra-short impulses of light (10-15 seconds) that last only a quadrillionth of a second to create a spot as tiny as 1/100mm.

What can the femtosecond laser be used for?

The laser is used to treat patients with thinner corneas or those with more severe nearsightedness or farsightedness. It can also be used to treat patients with opacities or warped areas of the cornea.

How It Works

To make the corneal flap, the IntraLase FS60 Laser is focused into a tiny spot of energy that passes harmlessly through the outer layers of the cornea until reaching its exact focal point within the central layer of the cornea. There, the corneal flap procedure is initiated, silently and painlessly, with remarkable precision. Contrary to traditional lasers, the energy of the laser beam from a femtosecond laser doesn’t affect the tissue on the surface of the cornea, but rather reaches a specific predetermined depth inside the cornea.

You will not be able to see the laser and the procedure only lasts about 40-50 seconds per eye.

The IntraLase FS60 Laser can also be used to create the channels and entry cuts for placement of Intacs. Using the IntraLase FS60 Laser for this procedure assures that the two segments are placed at the exact same depth and removes the need for making the more surgically difficult mechanical channel.

Why we’ve invested in the IntraLase FS60 Laser:

IntraLASIK provides our patients with an extra margin of safety by eliminating potential complications from mechanical microkeratomes. This procedure allows us to perform LASIK on patients with thin corneas because we can make a more precise shallow flap, which allows us to correct higher levels of refractive error. It also provides both the patient and the surgeon with a higher level of confidence knowing the creation of the flap will be without complications.

The corneal flap procedure with IntraLASIK using the IntraLase FS60 Laser is painless and more comfortable as there is much less pressure placed on the cornea with the laser versus the mechanical microkeratome.

    • FEMTO LASER CATARACT SURGERY IS AVAILABLE IN OUR HOSPITAL ..
      CATARACT is the opacification of the natural lens. Because cataract is the most commonly performed operation in our hospital we have the principle of providing all the recent advances in the diagnosis and treatment of this disorder. Professor Mahmut Kaskaloglu is one of the most respected eye surgeons in Turkey and he performs all of the cataract operations in our hospital. Professor Kaskaloglu is a member of the American Academy of Ophthalmology, American Society of Cataract and Refractive Surgery, International Society Refractive Surgery, European Society of Cataract and Refractive Surgery. He teaches cataract surgery in courses and live surgery sessions all over Europe and Middle East. 25 years experience and the latest technology at our disposal explain the high success rate in our hospital. After the diagnosis is made the patient is examined by two state of the art systems. ZEISS IOLMASTER calculates the power of the intraocular lens to be implanted and Pentacam measures the corneal surface and thickness so that we can correct any preexisting astigmatism. With the utilization of the lastest technolgy Femtosecond laser many steps of the operation are done by computer controlled instruments making the operation more precise and safer.Technically the operation is called “Phacoemulsification with intraocular lens implantation.”On the day of the surgery after being evaluated by the anesthetist, drops are instilled to widen the pupil. Operation is done under topical anesthesia, which means “ONLY DROPS, NO INJECTION”. We use laser and sound wave energy to remove the cataract through a very small incision, which means “NO STITCH”. Average duration of the surgery is less than 10 minutes. The patient can go home after the operation. The intraocular lenses we use are by the top companies so that our patients enjoy excellent vision after the operation

Glaucoma is a disease in which the optic nerve is damaged, leading to a progressive, irreversible loss of vision. It is one of the leading causes of permanent blindness in the world. The disease affects more than 1 million people worldwide, but can be prevented with proper preventative eye care.

Glaucoma is a disease of the optic nerve, which is the nerve that connects your eye to your brain. This nerve transmits visual information from the eye to the brain, thereby allowing you to see. In most cases, glaucoma damage progresses very slowly, over a period of several years. However, sometimes this damage can progress more rapidly. As the damage to the nerve progresses, a person begins to lose vision. This loss of vision begins with the side, or peripheral, vision. This is vision that you may not be aware of, but that is very important in everyday activities such as walking and driving. The loss of this peripheral vision progresses as long as the disease is not treated.

If treatment is not given, then the visual loss can progress until it begins to involve the central and reading vision. It is at this point that a victim of glaucoma may begin to notice trouble with their vision. If treatment is still not given, the vision in the eye can be lost. Visual loss from glaucoma is irreversible. Because vision loss from glaucoma can never be restored, it is critical to detect glaucoma before significant damage has occurred to the nerve. Proper treatment for glaucoma can be prevent further loss of vision.

What causes glaucoma?

High pressure inside the eye is known to cause glaucoma. The normal eye continuously produces and drains fluid internally in order to maintain the normal shape and pressure of the eye. This normal shape and pressure is necessary for you to see properly. In glaucoma, there may be a blockage of fluid drainage or an excess of fluid production, which leads to high pressure inside the eye. If you have high eye pressure, the increased pressure may damage your optic nerve. Some people, however, are able to tolerate high eye pressure without developing glaucoma. The reason for this is unknown.

Some people develop glaucoma even without evidence of increased pressure inside the eye. In fact, recent studies show that up to 50% of people with glaucoma may not have high eye pressure measurements. For example, people of Japanese descent are more prone to have glaucoma without elevated eye pressure.

Many studies are in progress to discover the reason for glaucoma damage in people who do not have increased eye pressure. The two leading theories are that damage to the nerve is caused by poor circulation to the nerve or that abnormally high concentrations of naturally occurring chemicals or hormones cause the damage.

Scientists who believe that poor circulation causes glaucoma have used special ultrasound testing to show decreased blood flow to the eyes of some people with glaucoma. Many of these people with “normal pressure” glaucoma also have other problems with their circulation, such as heart disease, poor circulation to their legs and feet, or hardening of the arteries.

Other scientists have shown increased concentrations of glutamate and other chemicals in the eyes of people with glaucoma. These chemicals are naturally produced by the body, and in normal amounts, help with normal eye functions. In abnormally high concentration, however, these naturally-occurring chemicals can actually harm the very nerve tissues from which they are produced. Scientists still have not discovered why the body produces abnormally high amounts of these chemicals in eyes with glaucoma.

Doctors and scientists are working to discover treatments to poor circulation to the optic nerve and treatments to decrease the concentration of these harmful hormones in the eye. Studies are under way to determine if improving circulation or decreasing the hormone concentration will help stop damage from glaucoma.

Who is at risk?

Glaucoma can strike people of any age, sex, and race. Certain individuals, however, are at increased risk. Those at increased risk include persons of African descent, those with a family history of glaucoma, and possibly those with nearsightedness or high blood pressure. The risk of glaucoma also increases as one gets older. The risk of glaucoma increases markedly in people of African descent over the age of 35 years, and in people of Caucasian descent over the age of 50 years. Other risk factors for glaucoma include diabetes and a history of trauma to the eye.

How is glaucoma diagnosed?

When the ophthalmologist examines your eye, he or she can detect glaucoma damage by the appearance of your optic nerve. A normal healthy nerve has a small cup-shaped hole in the center. As damage from glaucoma progresses, this hole in the center of the nerve enlarges, and replaces the healthy tissue of the nerve. Your eye doctor can detect progression of the disease by periodically examining the appearance of the nerve. Your doctor may also take photographs of the nerve in order to document the appearance at a specific point in time. This allows better comparison in the future to be certain that the disease has been stabilized.

These photographs, called disc photos, are particularly helpful if your doctor believes that you are a “glaucoma suspect”. A glaucoma suspect is a person whose optic nerve appearance is suspicious for glaucoma, but does not demonstrate definite glaucoma damage. If you are a glaucoma suspect, your doctor will want to examine your optic nerve two or three times a year, and compare to the baseline disc photos to detect definite glaucoma damage as soon as it occurs. This will allow your doctor to begin treatment before the glaucoma has a significant effect on your vision.

Another way to measure the amount of damage to the nerve is to measure the amount of peripheral or side vision that has been lost. Glaucoma does not affect your central reading vision until the late stages of the disease. At this late stage, vision may already be deteriorated to the point of partial blindness. Therefore, it is important to measure the peripheral vision in the early stages of the disease, so that proper treatment can be given to prevent blindness. This is accomplished with visual field testing, which is an examination that measures the amount of vision lost.

To test the visual field, your doctor uses an instrument that flashes lights of various intensities. You place your head against a head rest and stare at a target light directly in front of the eye being tested. The machine then flashes lights in your peripheral vision. Some of these lights are bright and easy to see. Others are so dim that they are impossible to see even if you have no visual damage. Most lights are somewhere in between. When you see the light, you press a button and the machine registers your response. The machine then prints out a map showing any areas that you cannot see properly. Your eye doctor can repeat this measurement periodically to determine if the glaucoma treatment has been effective in stabilizing the damage.

There are other types of specialized testing that have recently become available, such as measurement of the thickness of the nerve with a technique called scanning laser polarimetry (GD Nerve Fiber Analyzer), and short wavelength perimetry, which uses colored lights to test the visual field (peripheral vision). Both of these technologies are particularly helpful if a person is suspected of having glaucoma, but there is no definite damage visible (glaucoma suspect).

Are there different types of glaucoma?

The most common type of glaucoma is open angle glaucoma. Open angle means that there is no visible obstruction to the drainage area inside the eye. It is thought that there may be an invisible obstruction to fluid drainage in the trabecular meshwork, which is the structure in the eye that drains the fluid.

Another type of glaucoma is narrow angle glaucoma. In this condition, an obstruction to the drainage area inside the eye occurs. This type of glaucoma is most common in persons of Chinese descent and Vietnamese descent, and less common in persons of African and Caucasian descent. However, it can affect a person of any race. This type of glaucoma may cause symptoms of sudden pain, redness, blurred vision, and colored haloes around lights. This condition is called acute narrow angle glaucoma, and must be treated immediately. Failure to treat this condition immediately can cause permanent loss of vision. Sometimes narrow angle glaucoma is a chronic condition that does not cause any symptoms, like open angle glaucoma. Your doctor can determine if you are at risk of narrow angle glaucoma by performing a procedure called gonioscopy.

How is open angle glaucoma treated?

There are several ways to treat this problem. Most commonly, treatment begins with eye drops that are designed to lower the pressure in the eye. These drops are from once to four times daily, depending on the medication. These drops are designed to decrease the amount of fluid produced in the eye, or to increase the amount of fluid drained from the eye. There are also oral medications that are available to lower the eye pressure. Like all medications, these eye drops can have side effects. When treatment with eye drops is started, you should discuss with your doctor the potential side effects and interactions with other medication that you may be taking.

Another way of treating glaucoma is with a laser. This laser is designed to increase the amount of fluid drained from the eye, thereby lowering the pressure in the eye. The laser treatment is usually performed in the office, takes only a few minutes, and is normally painless. The third way to treat glaucoma is with microsurgery in the operating room. In this procedure, a small drainage hole is created in the eye, usually behind the eye in the eye socket. This drainage allows the eye pressure to be lowered, thereby preventing further damage from glaucoma.

Open angle glaucoma is generally a disease that stays with an affected person for life. Whether the treatment has been with medications, laser, or microsurgery, the victim of glaucoma must continue to be monitored by the ophthalmologist several times a year. Your doctor will monitor the eye pressure, the appearance of your optic nerve, and will periodically test the peripheral, or side, vision (visual field) to be certain that the disease has been stabilized, and that further loss of vision will not occur.

How is narrow angle glaucoma treated?

Your ophthalmologist will check to see if you have a narrow drainage area in your eye in order to know if you are at risk of developing narrow angle glaucoma. Your doctor will perform an examination known as gonioscopy to evaluate your risk. If you are at risk for narrow angle glaucoma, your ophthalmologist will recommend a preventive laser treatment. If you already have narrow angle glaucoma, this sometimes is cured with laser treatment. Sometimes narrow angle glaucoma is a chronic condition that is treated with the same medicines or microsurgery described above for open angle glaucoma.

How can I be sure that glaucoma does not affect my vision?

The best way to prevent visual loss from glaucoma is through regular eye examinations by an ophthalmologist. Eye examinations are recommended for adults as follows: once yearly between the ages of 19-35, three times between the ages of 35-50, every two years between the ages of 50-65, and yearly thereafter. More frequent examinations are recommended if you have any problems with your vision or have a family history of glaucoma (every 1-2 years). More frequent examinations are also recommended if you have certain medical conditions, such as diabetes or high blood pressure. For children, routine yearly screening examinations by the pediatrician are usually sufficient, unless an eye appears abnormal, or the child has trouble seeing.

Kaskaloglu Eye Hospital also diagnoses and treats retinal diseases caused by diabetes. The hospital’s main diagnostic device is digital fluorescein angiography and digital indocyanin green angiography. The major treatment device is the argon laser. A major breakthrough in the treatment of macular degeneration is photodynamic therapy (PDT), a treatment being used in our office since May 2000.

Diabetic retinopathy:

Diabetic retinopathy is the most common diabetic eye disease and a frequent cause of blindness in adults. It is caused by changes in the retina’s blood vessels. However, blindness caused by diabetes is preventable with proper control of diabetes and with yearly eye examinations.

Diabetes causes a problem with the blood vessels in the body. The blood vessels begin to leak fluid, blood and protein. In the eye, this leakage is seen in the retina as retinal bleeding and swelling. This blood and swelling interferes with the normal function of the eye, resulting in decreased vision. If this condition is not corrected, visual loss can be permanent. This type of retinopathy is called background, or non-proliferative, retinopathy.

Eventually, the abnormal blood vessels in the eye begin to grow. These abnormally growing blood vessels are very fragile, and especially prone to bleeding. These abnormal blood vessels may cause a large sudden hemorrhage, called a vitreous hemorrhage that can result in rapid complete loss of vision. Usually, this visual loss is not permanent, but vision may not return to normal after this hemorrhage. This type of retinopathy is called proliferative retinopathy.

The best treatment for diabetic retinopathy is prevention. All diabetics should check their own blood sugar daily and record the results in a journal. This should be shown to your primary medical doctor at each follow-up visit so that tight control of blood sugar can be achieved. This means that all fasting blood sugar measurements should fall within a very narrow range. If your blood sugar tends to fluctuate a lot, your doctor must adjust your medications and your diet to optimize control of your diabetes. This is the best way to prevent blindness from diabetes.

Diabetes can also cause premature development of cataracts. A cataract is a clouding of the lens of the eye, which can cause blurred vision, glare and difficulty focusing. The abnormal vessels in proliferative retinopathy are not limited to the retina of the eye. Sometimes, these abnormal blood vessels grow on the iris of the eye and cover the drainage angle. This blockage of the drainage angle results in accumulation of aqueous humor fluid in the eye, increased pressure in the eye, and, ultimately, in a type of glaucoma called neovascular glaucoma.

If prevention of diabetic retinopathy has failed, your ophthalmologist can use a laser to cauterize the abnormal blood vessels to stop the leakage of fluid and blood. However, these problems will continue to recur as long as the diabetes is not medically controlled.

Macular degeneration:

Macular degeneration is often related to aging and is thus often referred to as age-related macular degeneration. It is often abbreviated as AMD or ARMD. Most patients with AMD begin to notice problems sometime after age 50. AMD is the most common cause of legal blindness among people over age 60 in the Western world. The disease occurs in “dry” or “wet” forms. The cause of AMD is still unknown; however, researchers are exploring several theories as to how the disease develops.

AMD is a challenging disease for both patient and doctor because there are very few treatment options and no proven preventative therapy. Laser photocoagulation is the one treatment proven to be effective in clinical trials, but only a minority of patients with AMD are good candidates for treatment.

Photodynamic Therapy:

Visudyne was the first drug therapy approved for treatment of the wet form of macular degeneration. In this treatment procedure, the doctor injects Visudyne into your arm, then activates the drug as it passes through the retinal blood vessels by shining a low-energy laser beam into your eye. Visudyne is activated by the laser light, which produces a chemical reaction that destroys abnormal blood vessels. The procedure is virtually painless, according to Novartis, which makes the drug.

Any disease associated with rapidly growing tissue, including the formation of abnormal blood vessels, can potentially be treated with this technology. In addition to applications in cancer, photodynamic therapy has shown promise as a breakthrough treatment in ophthalmic, autoimmune and cardiovascular diseases.

Photodynamic therapy consists of a two-step process beginning with administration of the drug, or “photosensitizer,” by intravenous injection. While circulating in the bloodstream, the drug attaches to molecules called lipoproteins. Because cells undergoing rapid proliferation (cell division and growth) require a greater amount of lipoproteins than non-dividing cells, the drug is delivered more quickly and in higher concentrations to these types of cells.

Once the concentration of the drug reaches appropriate levels in target cells, it is activated with a pre-calculated dose of light at a particular wavelength much less damaging than the current thermal or hot laser treatment. Because the light is shone directly at the targeted tissue and the drug accumulates in these cells, it reduces damage to normal surrounding tissue, allowing for the treatment to be administered again as needed.

Because photodynamic therapy is a minimally invasive procedure that can be performed on an out-patient basis, it appears to be a cost-effective alternative to other treatments. The type of light source used varies depending on the indication being treated. In ophthalmology, diode laser light is shone through the slit lamp of a microscope into the patient’s eye.

PRESBYOPIA- THE NEED FOR GLASSES FOR READING:

Presbyopia  literally means the aging eye. Since presbyopia is an age related problem you cannot avoid it even if you’ve never had a vision problem before.  Nearsighted people who can see near well may notice that their near vision blurs when they wear their usual eyeglasses or contact lenses to correct distance vision. Presbyopia gradually becomes symptomatic after the age of 40 and increase as one get older.

Who can benefit from Presbyopia surgery?  Anyone who needs reading glasses will benefit, especially hyperopic patients who need glasses for distance near full time are the most grateful patients as they experience a big increase in the quality of life.

Presbyopia treatment: There are 3 choices: Glasses, contact lenses or surgery. We at Kaskaloglu Eye Hospital can offer you the three modalities.

  • Reading glasses: This is the simplest option.  If you need glasses for distance too you may choose multifocal glasses which can also be very expensive.
  • Contact lenses:  Multifocal contact lenses are very useful for young presbyopes. As one gets older most find their vision is compromised by multifocal contact lenses and feel uncomfortable due to dry eyes.
  • SURGICAL OPTIONS:
    • LASIK LASER SURGERY:  In younger presbyopes even correcting the distance vision improve the reading vision but the effect decreases by age.  Monovision is another option, here one eye is corrected for distance and the other is corrected for near. The aim of monovision is to provide comfortable vision for most daily activities.
    • RLE with multifocal lenses:  RLE- refractive lens exchange with multifocal intraocular lenses is a permanent option for presbyopia.
    • KAMRA inlay: This is a small  and extremely thin opaque disk placed between the layers of the cornea of one eye by the aid of Intralase Femto laser. The effect is similar to monovision.

If you are told that you are not a good candidate for LASIK there are several choices for you, namely ICL, ARTISAN, ARTIFLEX and RLE.At Kaskaloglu Eye Hospital our surgeons are experienced in all of these techniques. After a detailed eye examination we will tell you ifyou are suitable for these techniques. Below you will find information about these techniques as well as links to the manufacturersweb sites where you can obtain more information.

Refractive Lens Exchange (RLE)
If you are tired of wearing glasses, but have been told that you are not a candidate for LASIK, there is another vision correction option that may be right for you. It’s called Refractive Lens Exchange (RLE). It can also be called Clear Lens Extraction (CLE).Unlike LASIK and other refractive surgery techniques that correct vision by changing the shape of the cornea, RLE corrects your vision by changing the focusing power of the eye?s lens. To do this, we replace your natural lens with a new intraocular lens (IOL).Like the lens of a camera, which focuses images sharply on the film, the eye’s lens focuses light and images on the retina at the back of your eye. With RLE, your natural lens is replaced with an IOL selected to give you the best vision for your needs. RLE is well suited for people over 40 because that is the age that most of us begin to lose the ability to focus up close. This occurs when the natural lens becomes less flexible, and no longer accommodates as well to changing its focus from distant to near vision. Then reading glasses or bifocals are needed for close work.Some IOLs used in RLE have a fixed focal length and do not accommodate. If you select this type, you may prefer to have your new lens provide sharp distance vision for driving, golf, and similar activities. Or you may want near vision for reading, computer work and other close activities. Or you can choose Monovision where one eye is corrected to see near. The choice is yours. Another option is a special type of multifocal  IOL that allows the eye to focus both up close and far away. This unique lens allows the eye to focus naturally without glasses. We only use the best intraocular lenses available from Alcon or Zeiss which give the optimal results. You can visit the Alcon (http://www.acrysofrestor.com/) or Zeiss (http://www.zeiss.de/C125679E00525939/ContainerTitel/acrilisa/$File/index_en.html) web sites for more information.Before the procedure, your eye is carefully measured using precision state-of-the-art laser and ultrasound instruments. These measurements are entered into a sophisticated formula to calculate the exact corrective power of your intraocular lens.While RLE is not right for everyone, it may be the option you are looking for. To find out if you are a candidate for RLE, or for one of
the other refractive procedures available at Kaskaloglu Eye Hospital please contact us. Here is a useful link for information on RLE:http://www.allaboutvision.com/visionsurgery/refractive-lens-exchange.htm

ICL ( www.staar.com)

The STAAR Visian ICL and the Visian TORIC ICL (Visian TICL?) are posterior chamber phakic intraocular lenses. Made of Collamer,
Staar’s proprietary collagen copolymer, the lens rests behind the iris in the ciliary sulcus. This unique material contains a small
amount of collagen, which provides excellent biocompatibility and superior optical capability. The lens is gently folded and injected
into the anterior chamber through a 3.0mm, temporal, clear corneal incision. The ICL is then carefully positioned by manipulating the
footplates of the lens posterior to the iris plane and into the sulcus

Q. Am I a candidate for the ICL?
A. The best candidates for the Visian ICL are between the ages of 21 and 50, with moderate to severe myopia or hyperopia with or
without astigmatism.It is best if the candidate has not had any previous ophthalmic surgery and does not have a history of ophthalmic
disease such as glaucoma, iritis or diabetic retinopathy.

Q. What are the advantages of the ICL?
A. The Visian ICL and Toric ICL are capable of correcting a wide range of myopia, hyperopia and astigmatism without the removal or
destruction of corneal tissue. The ICL is a small, foldable, injectable lens that is inserted through a tiny, 3 mm incision that does not
require sutures. The ICL provides predictable refractive outcomes and excellent quality of vision due to its placement inside the eye,
as well as its optical performance. The lens is made of a superior lens material called Collamer, which provides unparalleled
biocompatibility.

Q. What if a patient’s vision changes?
A. If there are major changes in ones vision the Visian ICL can easily be removed and replaced, or another procedure can be done at
any time. With the ICL, one can still wear glasses or contact lenses if necessary. The ICL does not help presbyopia, or the need for
reading glasses due to age.

Q. Can they dry out or get dirty like a contact lens?
A. No. The Visian ICL is designed to remain in place within the eye without maintenance. An annual examination done by your
ophthalmologist is recommended to make sure that everything is fine.

Q. Can the ICL be seen by the naked eye?
A. No. Because the lens is positioned behind the iris, neither you, nor an observer will be able to identify the lens in place. The
cosmetic appearance of the Visian ICL is perfect, and there is no way for a non-professional to notice that a visual correction is in
place.

Q. What are ICLs made of?
A. The material is called Collamer, a collagen co-polymer that contains a small amount of purified collagen. It is very biocompatible
(doesn’t cause a reaction inside the eye) and stable. It also contains an ultraviolet light filter. This material is proprietary to STAAR
Surgical.

Q. What is involved in the ICL procedure?
A. The ICL surgery is performed on an outpatient basis, which means that the patient has surgery and leaves the same day. Please note
that someone will have to drive the patient to and from surgery. A light, topical or local anesthetic is administered and there is very
little discomfort and normally no pain associated with the procedure. Some drops or perhaps oral medication may be prescribed and a
visit is usually scheduled the day after surgery.

ARTISAN®/ ARTIFLEX® lenses (www.artisanlens.com)

Nowadays people from all around the world prefer not to be dependant on spectacles or contact lenses. They face problems while
wearing these or they feel that they no longer fit in a modern lifestyle. For these people refractive surgery could be a solution.
The ARTISAN®/ ARTIFLEX® lens is one of the most modern techniques of refractive surgery. This lens is a reliable, well performing
alternative for the popular laser treatments.

What’s an ARTISAN® or ARTIFLEX® lens?

An ARTISAN®/ ARTIFLEX® lens is an implantable lens that is implanted in the eye by an eye surgeon. The lens will stay there
permanently and therefore you will be able to see clearly all the time; your glasses or contacts will not bother or limit you anymore. It
seems as though you have no “refraction problem” any more. The lens needs no maintenance en can stay in your eye for the rest
of your life.

If you should need to replace the lens for any reason, this can be done without any problem in most of the cases. The lens can be
implanted in people of between 18 and 60 years of age, who meet certain conditions. The lens is available for shortsightedness (-3 to ?
23,5 diopter) and long-sightedness (+1 to +12 diopter); the cylinders (astigmatism) can also be corrected with the ARTISAN® lens. The
ARTISAN®/ ARTIFLEX® lens offers no solution for presbyopia.

Following a routine eye examination at Kaskaloglu Eye Hospital, your doctor will evaluate the cornea with an Orbscan which scans the cornea for detailed topography. In this way we can prescribe contact lenses that are best suited for your needs.

We keep the most standard contact lenses in stock at all times; cosmetic or fun lenses take a few days to come in. We can also provide free samples of brand name disposable lenses.

 

The following brands are available:

Wessley Jessen
CibaVision
Zeiss
Johnson&Johnson
Biomedics
Hydron

Are you over age 40? Need reading glasses?

What are contact lenses?

Contact lenses are thin, curved plastic disks designed to cover the cornea, the clear front covering of the eye. Contacts cling to the film of tears over the cornea because of surface tension, the same force that causes a drop of water to cling to the side of a glass.

What are contact lenses used for?

Contact lenses are used to correct the same conditions that eyeglasses correct:

Myopia (nearsightedness)
Hyperopia (farsightedness)
Astigmatism (distorted vision)
Presbyopia (trouble reading with age)

Special tinted contacts can be used to change the color of the eyes to various degrees. Contact lenses are sometimes used therapeutically in eye diseases where an uneven cornea blurs vision, such as keratoconus or scarring. They are also sometimes used for corneal abrasions to assist in healing.

What types of contact lenses are available?

PMMA lenses
Rigid contacts were the first lenses; they were developed in the 1960’s. They are made of a type of plastic called PMMA, which is very durable, but does not allow oxygen in the air to directly reach the cornea. When the eye blinks, the lens moves, which allows the oxygen dissolved in the tears to reach the cornea. While rigid lenses are probably the least comfortable type of contacts to wear, some users prefer them for their durability and lower cost.

Gas-permeable lenses
Newer rigid lenses made of plastic combined with other materials, such as silicone and fluoropolymers, allow oxygen in the air to pass directly through the lens. They are called gas permeable. Gas-permeable lenses are less durable than conventional rigid lenses but are more comfortable. Some gas-permeable lenses are extended wear and may be worn overnight for up to seven days.

Soft contact lenses
These lenses are made of plastic materials that incorporate water. The water makes them soft and flexible, as well as allowing oxygen to reach the cornea. Most of the contact lens wearers use soft contact lenses. Some soft contact lenses are extended-wear lenses, which means they are designed to be left in the eye overnight. It is recommended that extended-wear lenses be removed weekly, at a minimum, for thorough cleaning and disinfection. Some contact lenses are approved for wear up to 30 days. Soft daily wear lenses should never be used as extended-wear lenses. Extended-wear lenses can be used as daily-wear lenses. Studies have shown increased risk of corneal infections associated with extended wear contact lens use.

Disposable soft contact lenses
Disposable lenses for daily or extended wear have recently become available. The lenses are discarded and replaced each week. These lenses are convenient and may reduce the chance of allergic reaction and deposit formation.

Bifocal contact lenses
These lenses correct both reading and distance vision. They can eliminate the need for reading glasses.

What are the risks of wearing contact lenses?

Rigid lenses that are not gas permeable are more likely to scratch the cornea if the lens does not fit properly or if the lens is worn while sleeping. They are also more likely to slide off the cornea and become hidden under the lid.

Rigid lenses traditionally had a reputation for “popping out” of the eye. New lens designs have minimized the chance of losing a contact, even during vigorous exercise. Rigid gas-permeable lenses may allow more protein build-up than rigid non-gas-permeable lenses. Protein build-up results in discomfort, blurring and intolerance to the lenses. You will need special cleaning solutions to dissolve the protein.

Daily-wear lenses should never be worn as extended-wear lenses. Misuse can lead to temporary and even permanent damage to the cornea. People who wear any type of lens overnight have a greater chance of developing infections of the cornea. These infections are often due to poor cleaning and lens care.

What is the proper care of contact lenses?

Contact lenses must be properly cleaned and disinfected when you remove them to kill germs and prevent infection. At the time you insert your contact lenses, you should thoroughly rinse the case with warm water and allow it to dry. All contact lens cases need frequent cleaning, including disposable lens cases.

Soft extended-wear contacts are the most likely to have protein build-up and cause lens-related allergies. Soft daily-wear lenses are less likely to create problems. Rigid gas-permeable or disposable lenses may be good choices for someone with allergies.

Homemade saline solutions have been linked to serious eye infections and should never be used.
Any eye drops, even nonprescription ones, can interact with all types of contact lenses. Check with you ophthalmologist before you use any eye drops.

Who should not wear contact lenses?

Most people who need vision correction can wear contact lenses, but there are some exceptions. Some of the conditions that might keep you from wearing contact lenses are frequent eye infections, severe allergies, dry eyes, a work environment that is very dusty or dirty or the inability to handle and care for the lenses properly.
