PRELEX Explained


Your cornea (the outside part of the eye) and the eye’s natural lens (inside your eye) work together to focus light that comes into your eye on to the retina which is like a photographic film of a traditional camera. The lens, which is flexible when you are younger, becomes increasingly inflexible as you mature, often after you’ve passed the age of forty. Consequently, you have a difficult time focusing on objects. This condition is known as presbyopia.

The onset of presbyopia has traditionally meant that you are relegated to using reading glasses or cheaters for clear vision. And here’s a secret, even those individuals who’ve received laser vision correction will eventually become presbyopic and need glasses or contacts to restore their full range of sight.

Beverly Hills PRELEX offers a solution. Unlike procedures that focus on changing the shape of the cornea, PRELEX works on the dysfunctional lens inside the eye. Consequently, your vision after the procedure will be stable and unlikely to change over time. In addition, cataract surgery will not be necessary later in life. The presbyopic lens that is used to replace your eye’s natural lens will provide you with clearer vision at all distances, giving you little or no dependence on traditional or progressive bifocal glasses.

How is the PRELEX procedure performed?

Dr.Khanna  removes the eye’s dysfunctional lens using pressure waves and replaces it with a small plastic presbyopic lens. It is then unfolded and placed into permanent position. Patients go home soon after the procedure to relax for the rest of the day. Many patients report improvement in their vision almost immediately Some patients have gone to work the same day. Everyone heals somewhat differently, and most return to their normal activities within a day or two. PRELEX is usually performed on the second eye a week to two after the first procedure.

PRELEX vs. LASIK?

Although Los Angeles LASIK surgery may reduce the need for glasses or contacts, it cannot correct presbyopia and restore the eye’s full range of motion. An additional advantage to PRELEX surgery is that once you have had the procedure, you will not require cataract surgery later in life.
