Prelex Lens Exchange to cure Presbyopia

Prelex Lens Exchange (Presbyopic Lens Exchange) or PIE

Serving Los Angeles, California and Surrounding Communities

Prelex Lens Exchange (PRELEX) or PIE is a revolutionary refractive surgery procedure for patients who have presbyopia – a universal eye disorder that occurs as you age. Presbyopia causes the natural lens of your eye to harden and become inflexible, limiting your ability to focus on near objects. If you are under forty you need not worry about this disorder just yet. If you are in mid to late forties you will know what I am talking about. Extending your hands to read better. Requiring extra light to see better. Or you may have succumbed to using reading glasses. They are also called cheaters.

You may have faced problems like forgetting your reading glasses and unable to read the menu at Spurges in Beverly Hills. Some single people have said they feel embarrassed to take out their reading glasses on dates. It gives away their age! They have ended up ordering dishes they hated.

Prolix lens exchange corrects this problem by replacing the old dysfunctional natural lens of your eye with a new artificial lens. It’s the same type of procedure that is performed for cataract surgery patients, who need a new lens because their natural lens has become cloudy and opaque.

Are You a Candidate for PRELEX lens exchange?

PRELEX is primarily designed for presbyopia patients, but it can also correct vision in patients who do not medically qualify for LASIK eye surgery or PRK (Photorefractive Keratectomy). Situations like this can include thin corneas, or corneas suffering from Keratoconus, Keratoglobus or pellucidal marginal degeneration. Dry eyes may also be a factor in choosing Prelex lens surgery or PIE over Lasik eye procedure.

You may be a good candidate for PRELEX if:

  • You have early signs of cataracts
  • You’d like to depend less on bifocals or reading glasses
  • You have moderate to severe myopia or hyperopia

Many different types of refractive lenses can be used in a PRELEX procedure. After carefully examining your eyes, Dr. Khanna will recommend the best lens for your unique needs.

The Advantages of Prelex lens exchange

Almost everyone who undergoes PRELEX lens exchangewill not need glasses for distance vision, and most patients will not need reading glasses either. Another major advantage of PRELEX is that it prevents cataracts, since they cannot form in an artificial lens.

Other benefits of the PRELEX procedure include:

  • Minimal side effects
  • Fast vision stabilization
  • Proven history of success
