Refractive Lens Exchange (RLE)
With refractive lens exchange, also called lens replacement eye surgery, a clear lens is implanted to replace your eye’s natural lens to correct your vision. The procedure is often used for pre-cataract patients, as a preventative vision correction solution.
-
Nearsightedness
Myopia, also known as nearsightedness, is a common type of refractive error where close objects appear clearly, but distant objects appear blurry.
-
Astigmatism
Astigmatism causes your vision to be blurred at both near and far distances. It occurs when your cornea is shaped more like a football than a basketball.
-
Farsightedness
Hyperopia, also known as farsightedness, affects nearly one in four people. Those with hyperopia can see distant objects very well but have difficulty focusing on objects that are close.
-
Presbyopia
People with presbyopia often notice they need more light to read, and have to hold reading material at arm’s length to focus.
-
What conditions does refractive lens exchange treat?
If you have nearsightedness, farsightedness or astigmatism, even extreme prescriptions, and are over 40 years of age experiencing some degree of presbyopia, RLE could be your best course of treatment.
-
When should I consider refractive lens exchange?
You should consider RLE:
- If you are dependent on reading glasses or bifocals for your near tasks
- If you have a high level of farsightedness
- If you have been diagnosed with early lens changes and feel that the quality of your vision has declined, but, do not as yet have a cataract
-
How soon will I be able to resume normal activities?
Although you will need a ride home from the procedure, you will be able to resume most normal activities within a few days—with most patients able to resume driving as well.
-
What does the lens feel like when it’s implanted?
Patients are unable to feel the IOL, and intraocular lens implants have been performed for more than 50 years.
