The eye’s crystalline lens takes care of focusing images on the retina and as time goes by it loses its transparency and cataracts appear.
The aim of cataract surgery is to extract the clouded crystalline lens and replace it with a clear intraocular lens of suitable refraction for near vision.
The procedure consists of the extraction of the crystalline through a tiny incision in the cornea. Using the technique of laser phacoemulsification, the crystalline lens is destroyed and suctioned out and the new intraocular lens is implanted. This lens will carry out the work of the transparent crystalline lens.
Laser cataract surgery is a painless procedure that does not require injections since a topical anaesthetic is used. At the same time as cataract correction is carried out, presbyopia can be treated, eliminating the patient’s need for spectacles. The only requirement is that the implanted lens should be doubly adapted to resolve crystalline cloudiness and accommodate for near vision as well.
