Some vision changes can't be corrected with a laser, but they can be corrected by replacing the lens itself.
What Is Refractive Lens Exchange?
RLE removes the eye's natural lens and replaces it with an artificial intraocular lens, or IOL, permanently correcting your prescription. It's essentially the same procedure as cataract surgery, with one key difference: it's performed before a cataract has formed, purely to correct a refractive error rather than to treat clouded vision.
Because the natural lens is removed, patients who undergo RLE will never develop a cataract in that eye later in life.
