What is PRELEX?

Serving Orange County, California and Surrounding Communities

PRELEX is an acronym for presbyopic refractive lens exchange. The term was coined by Dr. Kevin Waltz. This new and exciting technology provides patients with a range of clearer vision at distance, near and everything in between. It is similar but better than the traditional bifocal or progressive lenses. This procedure is a viable option for those who wish to eliminate their dependence on glasses, or those who may not be ideal candidates for LASIK. PRELEX is a surgical procedure that is performed on an outpatient basis and takes only around 7-12 minutes. Prelex is a culmination of the development of ultrasmall incision cataract surgery, the development of advanced lasers and as we shall see the discovery of pressure waves to dissolve the lens.

Presbyopia – Inability to See Near Objects

If you’re age 40 or older, you’re probably finding it increasingly difficult to put near things into focus. As you grow older the hands don’t stretch far enough to bring things into focus. It’s a little harder to clearly see the face of your wristwatch, make out those road signs on the highway before you pass your exit, or even read the fine print on your TV, without glasses. This condition is known as presbyopia. And it continues to progress as we age.

In recent years, laser vision correction has made it possible for millions of individuals who are nearsighted and farsighted to eliminate, or greatly reduce, their need for glasses and contacts. Although laser vision correction can treat these conditions, it cannot yet correct presbyopia or restore the eye’s full range of vision in people above 45 to 50.

Enter PRELEX. This revolutionary procedure can improve your vision and provide clearer focus at all distances – near, far, and in between.

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.

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.
