Intraocular Lens Options
Modern cataract surgery has seen many advances during the last few years. An intraocular lens, which is placed at the time of cataract surgery, can now offer correction of astigmatism, nearsightedness and farsightedness. There are also special lenses which can correct both near and distance vision.
The astigmatism correcting lenses are called Toric intraocular lenses. Astigmatism means the eye has different radii of curvature in the vertical and horizontal axes, as would a football lying on the ground. In the past, these patients would require glasses to correct the astigmatism after their cataract surgery. Now they can have good distance vision without glasses in most cases.
Another really exciting new development is the advent of lenses which correct for both distance and near. There are two types of lenses in this category, Multifocal lenses and Accomodating lenses. Multifocal lenses have rings which allow the patient to have two focal points, one for far and one for near. Accomodating lenses allow some movement of the intraocular lens to adjust for various lengths of focus. There are lots of considerations that might make a patient a better candidate for one lens rather than another. These will be discussed with you at the time of your appointment after it has been determined that cataract surgery would be helpful.
All three of our cataract surgeons, Drs. Feinberg, Gabianelli, and Khator utilize these new exciting categories of intraocular lens implants. Be sure and ask about these during your next appointment!
