Cataract surgery becomes necessary when the vision is impacted because the lens in the eye becomes foggy. While there are times when the cataract can be removed without removing the lens, in most cases, the lens in the eye is replaced with an artificial one. When this is the case, the lens that is implanted can often be one that corrects other vision problems that were not related to the cataract. The implanted lens serves a similar function as a contact lens, only it is permanent and is not removed and replaced the way a contact lens is. The new artificial lens is called an intraocular lens (IOL).
To help patients gain the most from the surgery, our doctors can install either a monofocal IOL or a multifocal IOL. The purpose of a multifocal IOL is to help improve vision at various distances in order to do away with or reduce the need to rely on glasses. It may be that only reading glasses are necessary, or no glasses at all may be needed.
TECNIS® multifocal lenses have been available since 2009. They are designed to give high-quality vision at all distances and lighting levels. These lenses also work equally well regardless of the size of the pupil. Almost 90 percent of patients who receive TECNIS® multifocal lenses during their surgery are able to eliminate their glasses.
Sometimes, in order to get the maximum benefit from the new lenses following surgery, our doctor may recommend two different types of lenses in each eye. This may be two different multifocal lenses or a multifocal in one eye and a monofocal lens in the other.
The person’s lifestyle plays a big part in determining which lens combination is best. A person who spends a lot of time reading or using a computer may have different needs than someone who spends most of the time in activities that require distance vision. Our surgeon can help guide the individual through the process of deciding which is best. The doctor can also evaluate the overall eye condition to see if there are other issues that, after the removal of the cataracts, would interfere with getting the most from a multifocal IOL.
