Trifocal lenses, called smart lenses, have been used by specialists for a long term in cataract surgeries. Intraocular lenses are divided into two groups as monofocal and multifocal. The trifocal (smart) lenses, have 3 focuses. After this operation, patients can read books, use computers and watch television without glasses.
3 focused lenses, which are referred to as smart lenses, have become one of the most frequently used methods in our country for approximately 3-4 years. Multifocal lenses were generally used before trifocal lenses. However, when the problems related to the intermediate distance occurred in these lenses, the transition was made to trifocal lenses. The main advantage of these lenses is that they clearly show the intermediate distance that other lenses do not. This feature, which was not present in the previous lenses, was realized with trifocal lenses.
FOR WHAT ARE THEY BEING USED?
Trifocal lenses provide good vision in the distance and near, as well as good visibility in the intermediate distance. In order to apply this lens, patients must have cataracts. However, the fact that the patients are not suitable for laser treatment enables the use of this method. Trifocal lens treatment is performed for a maximum of 10 minutes per eye. During this process, the patient does not feel any pain. The cataract lens is removed during the surgery and smart lenses called trifocal are replaced. The patient can resume his / her normal life after this operation. However, it is still necessary to avoid heavy activities for up to 20 days. Trifocal lenses remain in the eye for a lifetime. These lenses can be applied successfully in all patients with near and far vision problems.
