Lens-based Refractive Surgery

Many patients are interested in eliminating or reducing their dependence on glasses or contact lenses. Laser vision correction (LASIK, PRK or other vision correction surgery) is the most common way to achieve this. There are also intraocular lens (IOL)-based solutions that may work better for some people. For example, if you have been told you are not a good candidate for LASIK, one of these lOL-based procedures may work for you.

People who are extremely farsighted may be candidates for clear lens exchange (also known as refractive lens exchange). The technique is the same one we use in cataract surgery, one of the most common procedures in the world. However, it is done before you have a cataract that affects your vision. This surgery can reduce or eliminate your need for glasses.

People between 21 and 45 years old who are extremely nearsighted may be candidates for the Visian Intraocular Collamer Lens. This lens is placed in the eye behind the iris, in front of the eye's natural lens. It may be a good option for patients who are too nearsighted for LASIK or whose corneas are too thin or irregular for LASIK.
