Lens implantation: In the past, in the treatment of cataract patients, one of the monofocal, or single-vision lenses, designed to see clearly near or far was used instead of removing the natural lens. In this case, it became obligatory for patients to wear glasses after treatment. For a long time, multifocal intraocular lenses have been used in place of single-focus lenses. Because these lenses allow to correct vision disorders from all angles, making vision as natural as possible.
Multifocal lenses are designed in two different ways. These are two or three focus lenses. When smart lenses are used in eye treatment of patients, there is no need to use glasses after treatment. These people can read books without glasses. However, they can easily see distant writing. Trifocal lenses are the most advanced intraocular lens technology today. It positively affects the quality of life as it provides an uninterrupted and clear vision for near, medium, and long distances.
Smart lenses are used when the natural lens in the eye loses its clarity for various reasons or cannot function functionally. The most important area of use is cataract discomfort. Cataract treatment is based on the principle of removing the lost clarity eye lens from its capsule and replacing it with an artificial lens. There are three types of smart lenses: monofocal, multifocal, and trifocal lenses.
Monofocal Lenses are lenses that are implanted through a small incision at the edge of the cornea (minimally invasive) that allows you to see clearly at a distance. And monofocal Smart Lenses also allow you to see a certain distance clearly without glasses, as they correct ametropia (myopia).
Multifocal contact lenses contain multiple degrees in a single lens. There is one degree for very close objects, one degree for normal objects seen from a distance, and one degree for objects in an intermediate distance.
Trifocal lenses are intraocular lenses that provide clear vision without glasses at far, medium, and near distances. While single-vision lenses that only clarify distance vision require the use of close glasses, these lenses are trifocal and eliminate the need for glasses thanks to these foci. Thus, patients can do their remote (watching TV, seeing the stage in the cinema and theater, driving), medium (using a computer or tablet, cooking, seeing the speed chart while driving, reading barcodes in markets) and close distance (using a phone, doing handicrafts) activities without glasses.
Eye drops are applied to you before and after the operation. In addition, intraocular needle treatments may need to be applied during surgery. Female patients should not wear make-up when coming to the operation. If you are taking blood thinners, you should definitely stop taking these medications a week or ten days in advance. However, you should also do this under the control of a doctor. If you have a chronic illness, inform your doctor about it.
Treating problems such as dry eye and eyelid inflammation in the preoperative examination reduces patient complaints after surgery and increases patient satisfaction by providing clearer vision. If there are other problems such as pterygium on the eye surface other than cataracts, surgery is performed first. Then the decision is made again with a detailed examination for the planning of the smart intraocular lens.
Very rarely after surgery, there may be a need for glasses to see more clearly from far or near. Blurred vision caused by fogging behind the smart intraocular lens can be corrected in seconds with a laser.
Although very rare, there may be unexpected errors in the calculation of intraocular lens strength (Biometrics) before surgery. These errors, which are due to millimetric or smaller differences in eye structure and measurement values between people, have been greatly reduced with high-tech measurement (Biometrics) devices. If it is necessary to use the near or far glasses due to unexpected measurement error after surgery, the problem can be solved by resetting the glasses number with a laser or changing the intraocular lens.
The most important disadvantage of multifocal smart intraocular lenses compared to normal lenses is that they scatter light more often and glare. In fact, this rare complaint has been greatly reduced in the new model smart lenses and already improves over time enough not to disturb the patient. Nevertheless, the patient’s profession and daily needs and some of the features determined in the detailed examination are guiding which patient will be suitable for the smart lens before surgery.

You can return to your country after the lens implantation. But it would be better to stay here for two or three days to reduce the risk of developing a complication. After a day, if everything is in order, you can return to your country.
You need to be here on the day of the operation. You do not need to arrive a few days before the operation. But if you have planned a tour here, you can arrive earlier.
These lenses can stay in your eye throughout your life. It is applied very often because it is already a permanent treatment.
Lens replacement surgery allows patients to return to normal life within a few days. However, it is considered one of the safest medical procedures. Although it has some small risks that can be eliminated with additional treatment, such as redness and itching in the eye, it is a safe procedure.
You will not feel pain during lens implantation. Surgery is usually done with relaxing medications. This is generally local anesthesia.
Some side effects of lenses can include: corneal edema, leakage, increased intraocular pressure, retinal detachment, and IOL power miscalculation.
During the first few days, you need to avoid activities that are strenuous to your eyes, such as driving. At the same time, be careful not to rub or wet your eyes. Follow your doctor’s advice.
The recovery time for this operation is about two weeks. You will need to use anti-inflammatory and antibiotic eye drops to help with recovery. You will be freed from lens changes. At the same time, a few days of mild discomfort and glare or blurred vision are completely normal while your eye calms down.
UV rays are one of the leading causes of cataracts. For this reason, you should protect your eyes from UV rays. If you don’t, you may even cause your cataracts to return. That’s why you should wear sunglasses outside for the first year after your surgery.
It takes a while for patients to fully recover their sharpest vision after cataract surgery. It takes them about four weeks to see clearly. However, this period varies from person to person.
What you should avoid after a cataract operation is generally as follows: You should not drive for less than 24 hours after the operation. Do not wear makeup until your first check-up. Continue light activities for a while. Do not be in environments that you think are dirty. And don’t forget to light your sunglasses. Do not rub your eyes.
It takes about 8 to 12 weeks for your eyes to fully heal after the operation. During this time, protect your eyes with sunglasses. At the same time, sleep at night with your eye shield.
