Op. Dr. Lütfi Seyrek, an Ophthalmologist, stated that multifocal intraocular lenses have now replaced single-focus intraocular lenses, and as a result, there is no longer a need for distance or near glasses.

Dr. Lütfi Seyrek from Medicana Healthcare Group stated that single-focus intraocular lenses were used in the past for the treatment of cataract patients, and these patients had to use distance or near glasses after the surgery. However, nowadays, multifocal intraocular lenses are used, which eliminates the need for glasses. Dr. Seyrek explained that the new generation of intraocular lenses, such as multifocal (multiple focus), trifocal (three focus), or edof (enhanced depth of focus) lenses, are commonly referred to as "smart lenses" because of their special design that enables patients to read distant, intermediate, and near objects comfortably without glasses after the surgery. This technology is currently the most advanced lens technology available and can significantly improve the quality of life for cataract patients.

Dr. Lütfi Seyrek emphasized that the most important application area for smart lenses is cataract disease. He explained that during cataract surgery, the natural lens of the eye, which has lost its transparency, is removed and replaced with a lens that can remain in the eye for a lifetime. Additionally, smart lenses can be used in cases where the functional capacity of the lens inside the eye is compromised even before the formation of cataracts. This technique is particularly effective for patients over 40 years of age who have distance refractive errors such as myopia, astigmatism, and hyperopia, which can lead to near-vision problems. The surgery enables patients to get rid of distance and near glasses for a lifetime. The rings or enhanced depth of focus on smart lenses bend the light that enters the eye from distant, intermediate, and close distances and focus it onto a single focal point on the retina. This enables the lens to focus simultaneously on objects at near, intermediate, and far distances with a single lens.

According to Lütfi Seyrek, the main reason for changes in vision after the age of 40 is related to the eye's natural lens. He explains that with the surgery, the natural lens that causes the change vision is removed and an artificial lens is implanted, so no changes in vision are expected after the surgery. The smart lens surgery is performed with the eye being numbed with drops, and the procedure usually takes around 10-15 minutes for one eye. The surgery for both eyes is typically done at a one-day interval. After the procedure, if you feel well, there is no need to stay in the hospital and you can be discharged immediately. Within one day after the operation, your vision will significantly improve, and you can return to your work.
