Refractive Lens Exchange, RLE for short, is a surgical procedure to remove the eye’s lens and replace it with and artificial lens, called an IOL. RLE is very similar to cataract surgery except it is not done to remove a lens with a cataract, but simply to correct for vision issues that would otherwise require glasses.

Many cataract surgeons will not do Refractive Lens Exchange as that there are other measures (LASIK etc) that can be done that are less invasive and have the same sorts of outcomes. Other cataract surgeons do not feel that surgery of this type is appropriate for people simply looking to eliminate their need for glasses.

In Refractive Lens Exchange, they types of IOL’s used are called Premium IOL’s or LifeStyle IOL’s. These lenses, unlike there predecessors, can correct for both near and far vision issues. Of the various types of lifestyle IOL’s there are two main categories, Multifocal and Accommodating Lenses.

Multifocal lenses are lenses that have various regions to view through. They allow people to see at multiple distances. Accommodating lenses are lenses that “accommodate”, or change shape to allow for near, far, and intermediate vision.

While these lenses are very popular for use in cataract surgery, some surgeons have issues with their being used for anything but cataract surgery. This argument holds that unless the lens must be removed, due to a cataract, it is often unwise to remove it just so the patient doesn’t have to wear glasses or contacts. This is a decision each surgeon makes individually, but patients should always be very aware of the special risks before having this type of surgery.
