The only current treatment for cataracts is the removal of the clouded lens and replacing it with a clear intraocular lens of your eye required optical power. To remove the opaque lens, the surgeon uses a technique called phacoemulsification. This technique starts with a microscopic incision that will close by itself and through which instruments are introduced to break softly the cataract and afterwards suck the tiny fragments. Once the surgeon has removed the contents of the crystalline lens respecting its curvature (lens capsule), introduces a foldable intraocular lens placed within the capsular bag that previously housed the crystalline lens.
 
 Crystalline lens surgery, phacoemulsification, is currently a technique:

1. Very quick and painless.
2. Doesn't need general anesthesia. A few drops of anesthetic eye drops are enough.
3. With a fast visual recovery.
 
Current technology in the design and manufacture of intraocular lenses allows, in selected cases, implantation of multifocal lenses i / or toric lenses taking advantadge of the lens extraction surgery.  The Toric Multifocal Intraocular Lenses are designed to allow a vision without glasses both far and near. They are now regarded as one of the safest, most precise and predictable surgery techniques for the treatment of presbyopia or tired eyes. Your ophthalmologist will tell you if they are indicated in your case.
