Smart Lens – Who Can Have It? Who Is Suitable For Smart Lens Surgery? Smart lens (trifocal / EDOF / multifocal IOL) surgery is especially suitable for: People over 40 with visual defects such as nearsightedness or farsightedness Cataract patients – during cataract surgery, the natural lens is removed and replaced with a smart lens Patients with myopia, hyperopia, or astigmatism (if their eyes are anatomically suitable) Individuals who do not want to wear glasses or contact lenses Those with generally healthy eyes – no significant retinal or corneal disease It is not suitable for everyone; a comprehensive eye examination and doctor’s evaluation are required. What Is a Smart Lens? The term smart lens generally refers to multifocal intraocular lenses such as trifocal or EDOF (Extended Depth of Focus). These lenses are designed to provide clear vision at far, intermediate, and near distances. They are used in cataract surgery and preferred by patients who wish to reduce dependence on glasses. How Is the Surgery Performed? Performed under local anesthesia Takes approximately 8–10 minutes The lens is inserted through a tiny incision – no stitches are usually required Patients are discharged on the same day The interval between the two eyes is decided by the doctor – sometimes both are done the same day, sometimes a few days apart Recovery and Results Healing is usually fast; most symptoms decrease within the first weeks Vision gradually improves as the eyes adapt Halos or glare around lights may occur but usually lessen with time Temporary blur or fluctuations in sharpness can appear during the adaptation period Advantages, Disadvantages, and Risks Advantages: Clear vision at far, intermediate, and near distances – less need for glasses Corrects refractive errors and treats cataract at the same time Improves comfort and daily life without glasses Disadvantages / Risks: Not suitable for all eyes; some ocular conditions prevent implantation Possible visual effects such as halos and glare Some lens types (especially EDOF) have limitations for very close work Smart Lens Cost / Price Cost depends on the lens type (monofocal, trifocal, EDOF, toric) The surgical technique (e.g. femto-laser-assisted procedure) affects price The hospital, surgeon’s experience, and equipment also influence cost In Which Eye Diseases Is It Unsuitable? Macular (retina) disorders: smart lenses are not recommended Corneal abnormalities (irregularities or thinning) increase risk Lazy eye (amblyopia): results may be limited Advanced retinal diseases: reduce suitability Certain professions (pilots, drivers) require careful evaluation before surgery Differences Between EDOF, Trifocal, and Other Lens Types Trifocal lenses: provide three focal points – near, intermediate, and far vision EDOF lenses: increase depth of focus and offer smoother transitions, with less halo effect EDOF lenses may be less strong for very near vision The most appropriate lens type is chosen according to individual visual needs How Is Clear Vision Achieved at Different Distances? Trifocal lenses are designed to provide sharp vision at all three distances. EDOF lenses excel for intermediate and distance vision but may be less effective for very close tasks such as reading tiny print. The lens type is selected based on the patient’s visual priorities and lifestyle. Halos, Glare, and Dysphotopsia Halos and glare around lights are common after surgery. These symptoms usually lessen as the brain adapts to the new visual system. In rare cases, they may persist but are generally mild. Lens Lifespan / Durability Smart lenses are designed for lifetime use – they do not need replacement. After implantation, vision remains stable, and cataract cannot recur since the natural lens has been removed. Can the Lens Be Removed or Replaced? Replacement or removal is rarely required. Smart lens surgery is a permanent solution and not intended to be reversed. If persistent problems occur, a specialist examines possible causes such as lens decentration or retinal issues. Interaction with Other Eye Diseases / Special Conditions In cases of diabetic retinopathy or macular degeneration, suitability for a smart lens decreases Corneal conditions such as keratoconus can reduce lens performance Lifestyle and profession (e.g. night drivers, pilots) should be considered when deciding on surgery Need More Information?
