Cataracts are a common condition among older adults. A cataract is a cloudy area in the lens of the eye. The lens is a structure that helps you focus on what you see. Cataracts develop for many reasons, including advancing age. Cataracts grow slowly. They may disrupt vision when they become larger. Cataracts do not need to be removed unless vision loss interferes with daily activities. Cataract surgery is very successful for most people.
Cataracts are a common condition in older adults. The tendency to have cataracts may be inherited. Smoking, alcohol use, diabetes, eye injury, radiation, certain medications, and toxic substances may contribute to cataract formation. Babies of mothers with certain risk factors may be born with cataracts or develop them in childhood.
As a cataract grows, you may notice symptoms. A cataract may make it difficult for you to see at night or read. You may experience double vision or multiple images in just one eye. Your eyes may be sensitive to glare. You may see halos around lights. Your vision may be blurred, cloudy, fuzzy, or filmy as a cataract decreases the amount of light that enters your eye. As the lens gradually turns a brown-yellow color, it may be difficult to distinguish blues and purples.
Cataract surgery is one of the most common surgery procedures in the United States. It is a short procedure with minimal pain and minimal risk. The surgery is perfomed on an outpatient basis. You may stay awake for the surgery with anesthesia to numb the area or you may use a general anesthesia to put you to sleep for a short time. You will need to have another person drive you home following your procedure.
Cataract surgery involves surgically removing the lens in the eye and replacing it with an artificial one. There are two main types of cataract surgery. Phacoemulsification, also called phaco or small incision cataract surgery, uses a tiny inserted probe that emits sound waves to break up the lens. The lens is removed with suction. Extracapsular surgery involves removing the cloudy part of the lens in one piece and removing the rest of the lens by suction. The phacoemulsification method is used most frequently. Your doctor will discuss the surgeries in detail and help determine which method is the best for you.
After the cataract is removed, the lens is replaced with an artificial intraocular lens (IOL). The IOL is made of clear plastic or silicone. It is carefully measured and fitted just for you. The IOL is a permanent part of your eye and requires no care. You will not be able to see or feel it. Select people may not be able to receive an IOL because of eye disease or problems from surgery. Instead, they may use a soft contact lens or high magnification glasses.
Initially, you will wear a patch over your eye to protect it. You will need to wear an eye shield or protective glasses as your eye heals. Your doctor may prescribe eye drops to promote healing and reduce the chance of infection. You should avoid bending at the waist, heavy lifting, or heavy chores while your eye heals.
Your surgeon will monitor your healing progress with follow-up appointments. Complete healing usually takes about eight to ten weeks. The majority of people have excellent results with cataract surgery.
Complications are rare but can be serious. Infection in the immediate postoperative period occurs infrequently. If you have pain or a very red eye, you should let your surgeon know. Retinal detachment occurs in about 1-2% of cases and could require additional surgery to repair. A less serious but relatively common complication is a film forming behind the implanted lens. This requires a brief laser treatment to open the film and is performed in the office.
Newer lenses now being used are called multifocal lenses. These allow you to read and see distance as your natural lens allowed.
