Refractive lens exchange (RLE) is a type of surgery that is used to correct refractive errors-errors in the way the eye processes light-that can cause blurry vision.
RLE is performed by removing the natural lens of the eye and replacing it with an artificial lens. RLE can be used to treat nearsightedness, farsightedness, and astigmatism, and it can be performed on both eyes at the same time or on one eye at a time.
The average age of a RLE patient is around 66 years old. However, RLE surgery can be performed on patients of all ages.
