What is Smart Lens Surgery?
Smart lenses are a type of treatment that offers solutions to multiple vision problems at near, medium, and far distances, rather than at a single focal point, which is what we call Trifocal lenses. Smart Lens Treatment is an option for patients who want to get rid of their glasses but are not suitable for laser treatment. It is a treatment method that eliminates refractive errors such as myopia, hyperopia, astigmatism, and presbyopia, as well as disorders such as cataracts. The eye number of the patients to whom this treatment is applied does not progress again, and cataract formation is prevented in the following years.
Our natural lens inside our eye starts to decrease its ability to focus near and far at the age of 40-45. These lenses inside the eye are transparent and elastic in structure. Thanks to their elastic structure, the lenses change shape and provide focusing during far and near vision, allowing for a clear image both far and near. Over time, lenses may lose their elasticity due to both age-related and genetic reasons. They cannot change their shape when looking at the near distance and cannot focus on the near, or they lose their transparency with the advancement of age and may cause cataract formation. In both cases, the quality of vision of the person decreases, preparing the ground for an uncomfortable social life. By cleaning the lens that has lost this focusing ability with the phaco method and replacing it with Trifocal lenses, we can provide clear vision at far, near, and even intermediate distances.
Who Does Not Apply Smart Lens?
- People with yellow spot disease
- Those with diabetic or other vascular damage in the retina
- Untreated glaucoma patients
Smart Lens Operation Details
The procedure takes approximately 10-15 minutes. Both eyes are not operated on the same day, unless the patient prefers it. We can perform a trifocal lens operation on both eyes with an interval of approximately one day. Since the procedure is performed under local anesthesia, the patient can be discharged on the same day.
Eye drops will be prescribed to prevent infection and reduce pressure after the procedure. You will be given instructions on how to use them after the procedure and will be invited for follow-up examinations.
Lens Groups Used in Cataract Surgeries
In the first group, monofocal intraocular lenses, the patient can see far away, but to see things up close, such as when reading books or newspapers, they need to wear reading glasses.
The second group of intraocular lenses are bifocal lenses with two focuses, one for near and one for far. The patient can see both near and far without glasses, but the middle distance, which is between 40 cm and 2 meters, cannot be seen clearly.
Trifocal intraocular lenses, also known as Smart Lenses, are trifocal lenses that solve this problem. When these lenses are worn, the patient can see far, near, and intermediate distances (between 40 cm and 2 meters) clearly without glasses.
What is Astigmatism?
Astigmatism, like myopia and hyperopia, is a refractive error that causes blurred vision both near and far. Every person has some amount of astigmatism. When the amount of astigmatism is small, it does not bother the person. When astigmatism exceeds 1 diopter, people’s complaints increase and astigmatism needs to be corrected with glasses, contact lenses, or laser surgery.
What is Toric Intraocular Lens for Astigmatism?
With new technological developments, it is possible to correct astigmatism during cataract surgery. Toric intraocular lenses are high-tech lenses that are implanted into the eye to correct astigmatism. If the patient’s astigmatism is related to the cornea layer and has a regular structure, toric intraocular lens application is performed during cataract surgery. These lenses can correct high astigmatism, and astigmatism up to number 6 can be corrected with very successful results. There are also lenses available that correct both astigmatism and distance, intermediate, and near distance (trifocal toric lenses), which are preferred for patients who want to see all distances without glasses. However, if the patient has diabetes, glaucoma, or yellow spot disease, monofocal toric lenses that correct astigmatism should be preferred instead of trifocal (multifocal) toric lenses. Therefore, it is essential that patients are evaluated by an ophthalmologist before surgery.
We Plan Eye Surgeries in Istanbul Turkey
Eye laser and smart lens surgeries are performed at a fully equipped eye clinic by specialist ophthalmologists. The average duration of your stay for these surgeries in Istanbul is 3-4 days.
Before scheduling the surgery, our assistants will explain the entire process to you. They will provide details on the procedures to be performed each day, hotel reservations, and airport transfers.
