What is Refractive Lens Exchange (RLE)?

Refractive Lens Exchange is another lasting way we can correct vision. In this procedure, we are changing the prescription by replacing the lens inside of the eye as opposed to changing the cornea in the front of the eye, like we do in LASIK. In our 20s and 30s, our lenses are still flexible, which allows for us to focus and see things from far away all the way to up close. When we get into our 40s and 50s, we lose that flexibility which makes things difficult to see things up close, leading to the need for readers. The reason for this difficulty, is as we get older, proteins start to build up on the lens, which diminishes the quality of vision. Additionally, this build up stiffens the lens, which makes it harder for the lens to flex and change their focus from distance to near. That is why we typically notice ourselves holding things farther away from us to see them.

With RLE, we are easily able to correct this by replacing the old, hardened lens with a new, clear lens. This isn’t a new procedure as lens replacements have been performed for over 50 years. There are some distinct advantages to Refractive Lens Exchange. In RLE, we are replacing the lens with a permanent lens that you can use the rest of your life. Furthermore, cataracts usually develop in our 50s on the natural lens but by replacing this lens with a new, clear lens, you will never develop cataracts or need to have cataract surgery. You will be able to enjoy the use of these lenses the rest of your life.

Who is a Candidate for RLE?

• Over the age of 45, with nearsightedness, farsightedness, and/or astigmatism
• Noticeable worsening vision quality due to the following:
  • Presbyopia (loss of near vision)
  • Dysfunctional Lens Syndrome
  • Early signs of cataracts
• Not a good candidate for LASIK but want the freedom from the pains of contacts and glasses, including readers.
