Cataract surgery involves replacing the altered crystalline material with an artificial lens or intraocular lens.

With age - from the age of 55 or so - the crystalline lens becomes harder and more opaque. This causes that each time between less light and we see the more blurred images. Once the process begins it is irreversible and each time the vision will get worse. The only way to end it is through surgical intervention. There are no alternative methods, or exercises, or drops that can eliminate cataracts.

The intervention lasts about 10 minutes per eye and at the end of the patient can go home on their own. The vision begins to be more than acceptable from the next day.
