A cataract occurs when the normally clear lens of the eye becomes cloudy. As the cataract develops, the cloudiness no longer allows the lens to properly focus light on the back of the eye. This unfocused light causes vision to appear blurry or hazy. Development of cataracts has been associated with exposure to ultraviolet radiation. They are particularly prevalent in persons who spend a lot of time in the sun, such as fisherman. There is no known way to prevent the formation of cataracts.

There are three types of  intraocular lenses (IOL’s) available today:

Standard Monofocal Intraocular Lens -This type of lens provides clear vision at a single fixed focus, usually distance vision. Patients with this type of IOL may still require glasses for the correction of their near vision, intermediate vision, or in many instances both. Examples of these lenses include ReZoom by AMO and ReStor by Alcon.

Multifocal Intraocular Lens - These lenses are designed to provide excellent distance vision and functional vision for near tasks without the need for glasses.

Toric™ Lenses - Can reliably correct a large range of astigmatism and provide superior distance vision relative to the traditional IOLs.
