One of the leading causes of blindness in the world, the cataract is a disease characterized by the loss of transparency of the lens, a natural lens whose function is to focus the vision at different distances. As the age progresses, the fibers of the lens increase in thickness and diameter, leading in principle to presbyopia, the popular tired sight. This is why most people over the age of 45 must wear glbades to see up close.
And it's as if cataract was the next phase of this process – the natural lens, in addition to losing its elasticity, becomes opaque A gradually blurred vision grows until it is dark. individual only sees lumens and lights, and blindness can occur.
Cataracts progress slowly, but there are rare cases where they are conbad – babies are born with vision altered by the influence of DNA. In other situations, the child is reached because the mother had rubella, syphilis or toxoplasmosis during the first three months of pregnancy

The operation is performed under local anesthesia and consists of replacing the lens with an artificial lens, made to measure and according to the curvature of the cornea. The patient returns home the same day, with a recommendation to avoid shaking and tilting the head.
