Smart lens (trifocal IOL) technology is revolutionizing cataract treatment. Patients are no longer only freed from cataracts; they also gain the comfort of seeing near, intermediate, and far distances without glasses.
What Is a Smart Lens (Smart IOL)?
Known in the medical world as a trifocal (three-focus) intraocular lens, this technology consists of specially designed lenses that can refract light to three different focal points (near, intermediate, and far). While standard monofocal lenses usually only sharpen distance vision, smart lenses also eliminate the need for reading glasses. These lenses placed inside the eye are permanent.
Who Is Suitable for Smart Lenses?
- Patients diagnosed with cataracts who need surgery
- Individuals over 40–45 who do not want to wear glasses (presbyopia)
- Those with a suitable eye structure (regular cornea, healthy retina)
- Patients whose cornea is too thin or prescription too high for laser surgery
Smart Lens Surgery Process
It is the same as standard cataract surgery (phacoemulsification / phaco method). Under topical anesthesia, the clouded natural lens is fragmented and removed with ultrasonic waves. The smart lens is placed into the emptied lens capsule with a special injector. It takes 10–15 minutes per eye, and the patient can return home the same day.
Who Should Not Receive a Smart Lens?
Smart lens implantation is generally not recommended for patients with macular degeneration, advanced diabetic retinal bleeding, or irregular corneal structure. For full performance, the retinal layer must be healthy.
Frequently Asked Questions
Smart lens surgery is not difficult and is painless. The implanted lens is permanent, does not deteriorate, and does not change in prescription. Cataracts do not recur after surgery.
Frequently Asked Questions
How much do smart lenses cost?
Prices vary depending on the brand of the lens used, the hospital's technological equipment, and the surgeon's experience. For the most current price, information should be obtained from the hospital after a detailed examination.
Do I still need glasses after a smart lens?
Most patients no longer need glasses, but depending on individual eye structure, thin glasses may be recommended for some activities.
Are both eyes operated on at the same time?
Usually not. The two eyes are operated on a few days apart so that the most accurate lens calculation can be made for the second eye while the first eye heals.
