As we go through life, signs of aging are inevitable. One of those signs is a decrease in vision. A common reason for decreased vision is a cataract. A cataract is the “clouding” of the natural lens in the eye. While a cataract is considered a normal part of aging, the decrease in vision that often occurs a cataract can be improved with advances in medicine.. Early symptoms of a cataract can often be remedied with a change of eyeglasses or with better lighting. As the cataract progresses these options become unsatisfactory andundergoing cataract surgery can restore vision.
Cataract surgery involves removing the cloudy lens from the eye and replacing it with an artificial lens implant which then does the focusing.
Prior to recent advances, individuals who had astigmatism would generally need glasses to see clearly after cataract surgery. Astigmatism is a condition where the corneal surface of the eye is shaped like the side of a football as opposed to the regular rounded shape of the side of a basketball. Today, with the availability of astigmatism correcting intraocular lens implants, patients with astigmatism may be able to see clearly in the distance without the assistance of glasses. Likewise, there are “multifocal” intraocular lens implants. These can provide patients with reasonable vision for both reading and driving distances without so much dependence on glasses at either distance.
For patients who have both cataract and glaucoma, it is possible to implant a device at the time of cataract surgery to help control eye pressure. The iStent® is a small implantable device that is inserted at the time of cataract surgery and can reduce the need for glaucoma drops.
