LASIK Surgery For Bifocal Wearers

Lasik Bifocals Think you can't get LASIK surgery just because you need bifocals? Think again. Technology is changing day-to-day. Recent advances in laser surgery have produced a new type of multi-focal LASIK procedure that may help patients with presbyopia and other patient's requiring bifocal lenses.

This new but also experimental form of LASIK surgery changes the corneal shape in different zones allowing for multi-focal correction.

Presbyopia and Surgery
Presbyopia is a condition that often occurs later in life. It produces blurring vision when patient's attempt to see things closely, in part resulting from the natural stiffening of the eye's lens as it ages. This condition usually hits people in their 40s, and makes common tasks including reading or working at a computer difficult for patients.

More than 90 million people suffer from presbyopia every year. More and more researchers are looking for new ways to treat this increasingly common condition.

How do you know if you have this condition? You may find you need to hold objects at an arm's length to get a good look at them. You may suffer from frequent eyestrain or fatigue.

In the past, patients with presbyopia were offered progressive lenses or bifocal lenses. This type of multi-focal lens allowed the eye to focus on two points. Eyeglasses with bifocal lenses contained a prescription for nearsightedness and farsightedness. Progressive lenses work in much the same way, but offer a more gradual change between the near and farsighted lens, so no visible line existed between the lenses.

The New Presby Procedure
The new LASIK procedure being developed for patients with presbyopia is often termed "presby lasik." Some also refer to this procedure as multifocal LASIK because it works much like multifocal lenses do. It can provide vision correction for patients with near and farsighted problems.

How does it work? The laser used in presby LASIK reshapes the eyes surface in "zones" so the eye refracts light differently in these different zones. That way the LASIK procedure can address problems with both near and distance vision.

This surgery is still in experimental stages however. Researchers are still working to decide how the eye can be best manipulated to provide optimal results and optimal vision correction.

Researchers are finding that near vision problems may be best corrected by addressing the central parts of the cornea, while other researchers are finding some patients may benefit from corrections made to the peripheral area of the eye. At this point researchers are convinced the procedure works most effectively for farsighted people with a moderate need for visual correction for near vision. When the procedure is fully developed, it will be important surgeons screen patients carefully to ensure they are good candidates for the new procedure. So far studies prove very promising. So all the people out their wearing multifocal lenses have hope. Technology will provide answers sooner than you may think.

Is "presby lasik" still in the experimental stages? I would be interested in getting the surgery done since I am a sufferer of presbyopia. However, I want to be reassured that procedure is OK to get.
