What Are The Advantages And Types Of Smart Lenses
(Multifocal-Linsen)?

The multifocal lens is characterized by the special feature of enabling both near and far vision at the same time and defines itself as a special intraocular lens.

Advantages Of Multifocal Lenses

  • Until recently, 2 separate glasses were used for eye problems, both for distance vision (myopia) and for near vision (hypermetropia). Later, attempts were made to solve this situation with a single pair of glasses that allows both distance and near vision. However, thanks to advancing technology, multifocal lenses - the smart lenses - have made a significant positive contribution both in terms of vision and personal comfort.
  • Thanks to the rings in the intraocular lens, there is an opportunity to see both near and far. Multifocal lenses reduce or eliminate the need for glasses or contact lenses.
  • One of the most important features of these lenses is that patients who need cataract surgery get rid of the cataract while providing a solution to the problem of distance and near vision. This is an enormous advantage for the patient being treated.
  • ​To address the subject of cataracts with a brief explanation: with age, the lens loses transparency and causes cataracts to form. The cataract is surgically removed by melting and replaced with an artificial lens.
  • The procedure for the intraocular lens is the same as the standard cataract procedure.
  • For treatment with the multifocal lens method, important details such as the pupil size or other existing eye diseases are of great importance.
  • After all the necessary tests and controls, the treating expert makes the ideal choice of lenses for the patient. The lens remains in the eye for life.
  • The smart lenses simplify and shorten the operation, which is designed in such a way that the patient can return to everyday life immediately after the procedure.

What Are The Types and Functions Of Intraocular Lenses?

Monofocal lenses: as the name suggests, these are single-focal lenses that are used for long-distance vision, but glasses are required for close-up vision.

Bifocal lenses: This allows both near and far vision without glasses, but the distance between 40 cm and 2 meters cannot be seen.

Trifocal Lenses: Offer precise solutions as these are triple focused lenses. It is possible to see without distance limitations (40cm - 2 meters).

Another distinctive feature of these lenses is their ability to protect the eye from the sun's harmful rays and age-related diseases. Trifocal lenses are used in people aged 50 and older who have cataracts. In exceptional cases, laser treatments such as Lasik are not suitable for some patients over 40 years of age. If they do not want to use near and far vision glasses, cataract surgery can be performed if near vision deteriorates before a cataract forms.
