Dr. Bartels Reviews Lens Options for Cataract Surgery - The Medical Eye Center

During cataract surgery, the cloudy lens is removed and replaced with a new, clear intraocular lens that improves the vision. Intraocular lenses are most commonly made of acrylic. There are several different types of intraocular lenses that provide different functions. The most common type of lens is called a monofocal or standard lens. This lens has one focusing distance. It can be set for either close or far vision. Most people choose to have clearer distance vision and will then wear reading glasses for close tasks. With a monofocal lens, you may still need glasses for distance as well, depending on whether you have astigmatism. Some patients have pre-existing astigmatism, which means that there is some refractive error caused by the curvature in the lens or the cornea. The Toric lens is designed to correct the astigmatism, allowing you to see well without glasses for one focal point (either distance or close up). Finally, there are lenses that help reduce your dependence on glasses for all distances. Multifocal lenses have different zones in the lens set at different powers so you are able to see well at distance, intermediate and near. Multifocal lenses tend to have a higher incidence of side effects such as glare and halos. Extended depth of focus lenses have a more blended zone of powers, so you have clear distance and intermediate vision, with some functional near vision. Extended depth of focus lenses have less incidence of side effects, but you may still need reading glasses for very fine print. During your cataract consultation, your surgeon will review the measurements of your eyes and present the lens options for which you are a good candidate. Then, depending on your lifestyle and vision goals, you can make an informed decision on which intraocular lens is best for you.
