What Is PRELEX Surgery?

Many problems can arise as your eyes age, including eye aging and a defective natural lens. Over time, these issues worsen, causing your vision to become impaired. This process begins with a gradual loss of close focus vision, chronic eye strain, and headaches, resulting in glasses required. As your natural lens becomes cloudier, prescription lenses become necessary.

PRELEX stands for PREsbyopic Lens EXchange. It is a surgical treatment that substitutes your natural lens with a multifocal intraocular lens or IOL. PRELEX corrects your vision at all distances, removing or minimizing the need for glasses.

PRELEX is a similar technique to cataract surgery. Cataract surgery usually occurs later in life when your natural lens has become cloudy, a natural sign of aging, making your vision blurry.


Who Needs This Surgical Procedure?

PRELEX could be an effective treatment for:

  • People with presbyopia; a condition that impairs the ability to see nearby objects.
  • People over the age of 40 who want to ditch their glasses or bifocals.
  • People with developing cataracts.


The Advantages of PRELEX surgery are:

  • Eliminating the need for glasses
  • Correction for farsightedness and nearsightedness
  • Safe, science-proven, and out-patient (no hospitalization required) procedure
  • Fast and painless procedure
  • Quick recovery plus immediate results
  • Prevention of cataracts


A thorough examination is required to fully understand all of the alternatives available to repair your vision.
