As we age, the lens inside our eye loses its ability to focus both near and far. Most vision correction procedures attempt to change the focusing power of the cornea. Refractive Lensectomy, on the other hand, corrects nearsightedness or farsightedness by replacing the eye's natural lens, which has the wrong power, with an artificial intra-ocular lens (IOL) implant that has the correct power for the eye.
Refractive Lensectomy, or refractive lens exchange, is a surgical procedure that uses the same successful techniques of modern cataract surgery. These surgical techniques have evolved and improved dramatically over the last 20 years. Cataract surgery is now the most common surgical procedure performed in medicine today. However, Refractive lens exchange may be an option for you if you are not a good candidate for either LASIK or cataract surgery.
The main difference between standard cataract surgery and Refractive Lensectomy is that cataract surgery is primarily performed to remove a patient's cataract that is obstructing and clouding their vision, while Refractive Lensectomy is performed to reduce a person's dependence on glasses or contact lenses. Refractive Lensectomy can be combined with other procedures that treat astigmatism such as LRIs and AK. Some modern implants can even give great distance vision while improving the ability to see up close without glasses. We hear the phrase a lot: "too old for LASIK, too young for cataract surgery!"
