Refractive Lens Exchange is a surgical procedure that exchanges the natural lens of the eye with an artificial lens. The surgery is also known as lens replacement surgery and clear lens extraction procedure.
The procedure is recommended for people who are not a good candidate for LASIK or interocular ILO. The procedure is particularly effective for patients suffering from farsightedness. While the procedure could also correct nearsightedness, the doctors generally recommend LASIK or similar procedures that are far more effective in the treatment of nearsightedness.
An interesting fact about Refractive Lens Exchange is that the procedure is virtually similar to cataract surgery. The only difference is the health of the lens removed during the procedure. In the case of cataracts, the clouded lens is removed while in the case of Refractive Lens Exchange, the clear lens is removed. In both cases, an artificial lens is substituted.
There is no one-size-fits-all approach in the case of lens implant. The surgeon takes careful measurements of the eye and establishes the size and placement of the artificial lens.
Usually, the doctors prefer to do the procedure for both the eyes so that the patient could get rid of prescription eye glasses or contact lenses. The operations are spaced 7 to 10 days apart so that the previous operation could heal a bit. The procedure itself takes half an hour and is usually done on outpatient basis. The eye under the procedure is numbed through the application of drops.
