What are IOL's that i read about in articles from time to time?
Are they only used for cataract surgery or could they be used on someone post lasik to get a good correction rather than doing enhancement surgery?

An IOL is an Intraocular Lens. IOLs are artificial lenses that replace the natural crystalline lens within the eye. The most common use of an IOL is for cataract surgery. Cataracts means that the natural lens has become cloudy. This is a naturally occurring part of the aging process.

Cataract surgery is the process of removing the natural lens and replacing it with an artificial lens; an IOL.

In recent years the idea of cataract surgery for purely refractive purposes has become more popular. Called Refractive Lens Exchange (RLE),it is exactly the same procedure as cataract surgery, but with a different purpose. Cataract surgery is to remove a cloudly lens. RLE is to replace the natural lens with an IOL that changes the focus of light entering the eye to reduce the need for glasses or contacts.

For the most part, RLE is only appropriate for someone well past age 40 and/or fully presbyopic.
