Refractive Lens Exchange (RLE) is a surgical procedure that involves replacing the eye’s natural lens with an artificial intraocular lens (IOL). This is done to correct refractive errors such as nearsightedness, farsightedness, and presbyopia. Unlike LASIK or PRK, which reshape the cornea, RLE addresses vision issues by targeting the lens itself. The procedure is similar to cataract surgery but is performed to improve vision before cataracts develop. RLE is particularly suitable for individuals over 40 who want to reduce their dependence on glasses or contacts.
