Intraocular Lens Selection in Cataract Surgery

Today, there are many different options such as multifocal lenses called smart lenses, mono-focal lenses, astigmatism-correcting toric lenses, and EDOF lenses. Among these options, choosing the most suitable one for the patient is very important for a successful, trouble-free, clear vision in the long term, and most importantly, for a surgery where the patient's expectations are fully met.

After the lens selection is made, the day of surgery is determined, the drops to be used before the surgery are explained to the patient, the diabetes drugs used by the patient are evaluated, and if necessary, blood thinners are stopped for a day or two. It is recommended that the patient apply to the hospital at the specified time on the day of surgery.

What kind of lenses are used in cataract surgeries?

The artificial lens to be replaced by the eye lens, which is removed from the eye due to cataracts, provides a clear image by focusing the image on the retina, that is, the retina.

The more precisely the power of the lens placed in the eye is determined, the less likely the need for glasses will arise after the surgery. For this purpose, Professor Akman prefers the Zeiss IOLMaster 700, for which he has published research papers internationally. We can divide the modern intraocular lenses used today into four groups.

1- In the first group, there are single-focal lenses called standard lenses. When these lenses are adjusted in a far-focused way, they can show the distance clearly without glasses, but for near vision, that is, the reading distance, the patient must wear glasses.

2- In the second group, there are toric or astigmatism correcting single focus lenses. Unlike the standard lenses above, these lenses also correct the patient's distant astigmatism. Patients with single-focal toric lenses, even if they get rid of their distance astigmatism, have to wear near glasses to see up close.

3- Trifocal lenses, also called smart lenses, are in the third group. These lenses can be thought of as three lenses joined together. The first lens focuses on the distance, the second lens focuses on the computer phone distance, and the third lens focuses on the reading distance. In this way, patients with smart trifocal lenses have the chance to see clearly without using glasses at a distance, at a distance from the computer, and nearby.

4- In the fourth group, there are toric models of smart trifocal lenses, which are fitted to patients with astigmatism in their eyes. In patients with astigmatism, these lenses both correct astigmatism and provide vision without glasses at near, middle, and far distances.

Professor Akman is one of the most experienced surgeons, especially in astigmatic lenses, smart lenses, and astigmatic smart lenses. In addition to applying such lenses frequently and being experienced in this regard, there are scientific lectures given by Professor Akman about the correct usage of these lenses at national and international levels and training given to other ophthalmologists.
