PRELEX (Presbyopic Lens Exchange)

Serving Los Angeles, California and Surrounding Communities

Presbyopic Lens Exchange (PRELEX) 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.

PRELEX corrects this problem by replacing the old 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).

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

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
