What are cataracts?
Cataracts are the opacification of these natural lens-optics of the optical system.

Causes of cataracts
Cataracts can appear by age.

Cataracts have to be treated by a specialist in Ophthalmology. The technique used to remove the opaque lens is called phacoemulsification. This technique consists of making a small incision that will serve as an opening to eliminate the cataract slowly. Once removed, the surgeon will introduce an intraocular lens where the lens was.The results of cataract surgery are very satisfactory, patients who opt for tri-focal or multifocal intraocular lenses achieve excellent vision after surgery and do not have to wear glasses from near or far.
