Refractive Lens Exchange

Understanding Refractive Lens Exchange (RLE)

What is RLE?

Refractive lens exchange (RLE) is a surgical procedure that involves replacing the eye’s natural lens with an artificial intraocular lens (IOL) to correct refractive errors. It’s similar to cataract surgery but is performed on individuals without cataracts who want to reduce their dependence on glasses or contact lenses.

Who is a Candidate?

  • Individuals with high refractive errors (myopia, hyperopia, astigmatism)
  • Those seeking an alternative to LASIK or PRK
  • Patients over 40 experiencing presbyopia (difficulty focusing on near objects)

The Procedure

  • Pre-operative Assessment: A thorough eye examination to determine candidacy and lens type.
  • Anesthesia: Local anesthesia with mild sedation to ensure comfort.
  • Lens Removal and Replacement: The natural lens is broken up and gently removed using ultrasound (phacoemulsification), followed by the insertion of the customized artificial IOL.
  • Recovery: Patients typically experience improved vision within days and can return to normal activities quickly with a few small adjustments.

Benefits of RLE:

  • Reduces or eliminates the need for glasses/contact lenses.
  • Corrects presbyopia, allowing for improved near vision.
  • Can be tailored and customized for specific vision needs (multifocal, toric, etc.).

Post-Operative Care:

  • Follow-up appointments to monitor healing.
  • Use of prescribed eye drops to prevent infection and reduce inflammation.
  • Avoid strenuous activities for a brief period.
  • Many are able to drive the next day after surgery.
