Refractive Lensectomy

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 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.

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.

Refractive Lensectomy is for those who:

• want to reduce or eliminate their dependence on glasses or contacts
• may not be a good candidate for laser vision correction
• are 18+ years of age

Cataracts are a part of the normal aging process and if a person lives long enough chances are they will develop cataracts. People who have refractive lensectomy now, will not have to have cataract surgery in the future.

What to expect on surgery day:

The refractive lensectomy procedure is performed on an outpatient basis. Only one eye will be treated at a time. After the eye is completely numbed with topical or local anesthesia, the eye's natural lens will be gently removed through a tiny incision, about one eighth of an inch wide.

Next, the new, intra-ocular lens will be folded and inserted through the same micro-incision. It will then be unfolded and placed into the "capsular bag" that originally surrounded the natural lens. This incision is "self-sealing" and usually requires no stitches. It remains tightly closed by the natural outward pressure within the eye. This type of incision heals fast and provides a much more comfortable recuperation.

If your eye has pre-existing astigmatism, your surgeon may elect to make micro-incisions in the cornea to reduce your astigmatism. These are called LRIs or limbal relaxing incisions.

You will go home soon after the surgery and relax for the rest of the day. Everyone heals somewhat differently but many patients report improvement in their vision almost immediately after the procedure. Most patients return to their normal activities within a day or two. Several visits with your surgeon or doctor of optometry will be required.
