Refractive Lens Exchange
Refractive Lens Exchange (RLE) is a vision correction lens surgery designed to reduce or eliminate the need for glasses and/or contact lenses for people over the age of 40.
What is Refractive Lens Exchange?
Unlike LASIK, SMILE, or PRK, which reshape the cornea and don’t alter any other structure of an eye, RLE involves the same steps as the cataract surgery. The only difference is there is no visually significant cataract. After age 40, most people notice difficulty focusing at near. This is because a natural crystallin lens gradually loses its elasticity, its ability to focus at various distances, over a lifetime. This loss of elasticity becomes noticeable in early 40s. In RLE, the relatively clear natural lens is replaced with the advanced artificial intraocular lens (IOL), which enables simultaneous vision at far, intermediate, and near objects without glasses or contacts. Both eyes have to undergo RLE to substantially reduce the need for glasses and/or contact lenses.
As with any invasive surgery, there are several risks to consider. The following list of RLE complications is not comprehensive, but it includes most serious and most common complications.

Bottom line: the benefits and risks of RLE depend on the unique features of your eyes, and a more individualized estimate of your risk requires a thorough eye exam and a battery of diagnostic measurements.
