Lens replacement surgery, sometimes referred to as clear lens replacement, is another alternative to LASIK. CLR surgery replaces the natural lens and is a good option for those with thin corneas and farsightedness. The natural lens of the eye is replaced with an artificial intraocular lens during this procedure. Sharper vision is made possible by the improved lens. It’s possible for patients to stop using their reading glasses altogether. The procedure is comparable to cataract surgery except the natural lens is clear instead of clouded, as it is when a patient has cataracts.
