Refractive lens exchange (RLE) is a surgical procedure used to treat refractive vision problems and cataracts by replacing the natural lens of the eye with an artificial intraocular lens (IOL). RLE is often recommended for patients with presbyopia, severe nearsightedness or farsightedness, or cataracts that have developed.

During the procedure, the natural lens is removed, and a custom IOL is implanted to correct the patient's refractive error and improve vision. RLE can eliminate the need for glasses or contact lenses and can provide improved vision at various distances, depending on the type of IOL chosen.

RLE has become a popular option for older adults, offering a solution for both vision correction and cataract removal.
