What is lens replacement surgery?
In lens replacement surgery, your eye's natural lens is replaced with an artificial intraocular lens (IOL). This is similar to the procedure used to correct cataracts, except the lens being replaced is clear rather than clouded by a cataract. Lens replacement surgery is typically used for people who have extreme farsightedness (presbyopia) and who are not good candidates for LASIK or other forms of refractive surgery. More rarely, it can be used to correct nearsightedness (myopia).
