What Is Refractive Lens Exchange (RLE)?
Refractive Lens Exchange (RLE), also called clear lens exchange or lens replacement surgery, replaces the eye’s natural lens with an artificial lens to help correct your vision.
The surgical technique is similar to modern cataract surgery. The major difference is why the procedure is performed. Cataract surgery removes the cloudy natural lens, while RLE can be performed before a significant cataract develops to address refractive errors and age-related changes in the eye’s ability to focus. When the natural lens is removed during RLE, it cannot develop a cataract later.
