Refractive Lens Exchange (RLE) is identical to modern cataract surgery. The operation involves replacing the natural lens with an artificial lens implant. RLE is usually carried out to reduce the need for glasses or contact lenses.
Almost any level of myopia (short sight) or hyperopia (long sight) can be corrected by RLE. Astigmatism correction is also available.
The most important decision you will have to make before RLE is which type of lens you will choose to replace your eyes natural lens. Monofocal lenses allow you to see clearly in one distance. Most people aim to see well for distance (driving) vision but will require glasses for close up tasks like reading. If you would like to reduce your spectacle reliance further, trifocal lenses may be a good option for you. As their name suggests, trifocal lenses allow you to see well across all three focal distances (far, medium and close up).
A toric lens will correct astigmatism. Monofocal and trifocal lenses can also have toric properties.
