It is used to treat cataracts that are characterized by opacities in intra-ocular lens and impairs visual acuity.It is used to treat cataracts and allows safer cataract surgery.After the eye is measured precisely at micron level, all procedures of a cataract surgery are carried out with laser. Laser beams are used to prepare the location, where intra-ocular lens is to be placed, and to fragment the cloudy native lens.Since corneal incision is made with laser beam rather than blades, damage to surrounding tissues is minimized and moreover, astigmatism can be corrected. It eliminates the risk of decentralized intra-ocular lens used in cataract surgery. This eye surgery is performed quickly.
