  • Refractive Lens Exchange is a procedure that allows patients to restore their near, intermediate, and far vision with an implantable lens that replaces the eye’s crystalline lens.
  • It is especially suited for patients over 45 who are not LASIK candidates but have not yet developed cataracts.
  • Since the eye’s natural lens is replaced, Refractive Lens Exchange patients will never develop cataracts.

What is Refractive Lens Exchange?


If you’re not a candidate for LASIK and cataracts aren’t an issue, you may still be able to eliminate your need for reading glasses with Refractive Lens Exchange.

Refractive Lens Exchange allows patients to restore their near, intermediate, and far vision with an implantable, multi-focal lens that replaces the eye’s crystalline lens. This procedure is especially suited for patients over 45 who haven’t yet developed cataracts, but are far-sighted and dependent on bi-focals or tri-focals.

Most Refractive Lens Exchange patients have a condition called presbyopia, a common part of the aging process in which the eye’s crystalline lens loses flexibility and the muscles that focus the lens weaken. If treated with LASIK, presbyopic patients would still need reading glasses for all close-up vision, such as reading books or dialing a phone. Refractive Lens Exchange takes care of that problem.  Even better? Since the eye’s natural lens is replaced, Refractive Lens Exchange patients will never develop cataracts.

How We Perform It


The Refractive Lens Exchange procedure takes about 15 minutes.  The eye’s natural lens is removed using gentle ultrasound energy, and is replaced with an artificial lens called an Intraocular Lens Implant (IOL). Most patients see improvement in their vision immediately after the procedure, and experience continued improvement for the next three to six months.

Refractive Lens Exchange is performed one eye at a time on separate visits. Surgery in the second eye can usually be performed as soon as one to two weeks later. Following the procedure, discomfort is typically mild with no need for pain medication. Postoperative care includes follow-up visits and restriction of activities involving heavy lifting.
