The vast majority of patients who have undergone cataract surgery have an artificial intraocular lens (IOL) implanted to replace the clouded lens that is removed during surgery. Rarely, patients may have conditions that dictate against using a replacement lens, or, also rarely, the implant may need to be removed if it dislocates or is displaced by injury. In such cases, the doctor will prescribe eyeglasses or contact lenses to correct postoperative vision.
There have been major advances in surgical options for cataract patients. Many years ago, "traditional" cataract implants only partially corrected vision after surgery. Previously, cataract patients usually had to wear glasses for distance vision and almost always for near vision after having surgery. New "premium" lenses can allow patients to have good distance, intermediate and near vision, reducing dependence on glasses.
