People who have severe farsightedness (hyperopia), nearsightedness (myopia), presbyopia and astigmatism have an option to correct their eye conditions through an alternative to LASIK known as Refractive Lens Exchange (RLE). Since some patients with higher levels of correction may not be candidates for LASIK or PRK, RLE may be an alternative.
What is Refractive Lens Exchange?
Refractive Lens Exchange, also known as Clear lens extraction, is a procedure where the eye’s lens is removed and is replaced with an artificial lens to correct refractive errors. The lens is one of the parts of your eye that functions to focus light rays on the retina. In patients with hyperopia or myopia, the light rays are not focused exactly on the retina, causing blurred vision and the need for eyeglasses or contact lenses. In RLE, the artificial intraocular lens implant will allow your eye to focus the light rays in a precise area in the retina for vision correction.
RLE is commonly performed in middle-aged patients who have levels of hyperopia or myopia that cannot be corrected using LASIK or PRK, and who may also have presbyopia and very early signs of cataract formation. Astigmatism can also be corrected by RLE if needed.
