Cataract is one of the most common among eye diseases. The most important symptom of Cataract is the loss of vision, even if it is not completely, but in a way that harms the quality of vision.
Definition of Cataract in the medical literatüre is the visual impairment caused by the loss of transparency of the transparent lens located behind the pupil.
After the cataract is cleared from the anterior capsule of the eye, an artificial silicone lens is injected into it, and this lens remains in the eye for lifelong.
These lenses differ in brand and feature:
Monofocal: It is a lens that only shows far and requires the use of eyeglasses for near.
Trifocal (Smart lens): They are 3D lenses that provide images without glasses with far and medium distances.
