Cataract Surgery-Indications, Techniques, and Intraocular Lens Selection.

Deutsches Ärzteblatt International, 2023
BACKGROUND Opacification of the lens of the eye (cataract) is usually due to aging. It is a painless, progressive condition that affects contrast and color perception and alters refraction, leading to visual loss that may be total.
