Cataracts result from the natural aging of the eye. The lens inside the eye gradually turns hard over time, often making vision appear dull and yellow. As cataracts continue to harden, a person has more difficulty seeing. When cataracts make daily tasks, such as reading, more difficult, an eye doctor may recommend cataract surgery.
Blurry Vision During Healing
Once the eye heals after cataract surgery, vision often appears much clearer and brighter. However, while the eye heals, vision will likely seem blurry or cloudy, says the National Eye Institute. Doctors don't prescribe eyeglasses during this time because the healing process continuously alters the vision prescription needs. Though healing time varies, most people find vision improvement within a few weeks. Some people expect cataract surgery to resolve all vision problems. If a person has other eye conditions that result in vision loss, such as macular degeneration, cataract surgery cannot return lost vision.
You May Still Need Glasses
Many people expect that cataract surgery will allow them to see well without the need for glasses. Though true that some people don't require prescription glasses for distance vision after surgery, many people need glasses for good vision. A number of people find that they need glasses for driving but don't have to wear them constantly throughout the day. Most people find it necessary to wear glasses for reading.
Post-Surgery Care
After cataract surgery, you must make time to care for your eyes. Most doctors prescribe two or three different eye drops to use after surgery, and, usually in the first two weeks, you must use these drops four times a day. After a specified time, the doctor gradually decreases the number of drops used each day. Though necessary, the eye drops take time and effort, Because many people have a difficult time putting the drops in on their own. Doctors also require follow-up appointments. The first appointment usually occurs the day after surgery, a week later, and then four to six weeks after surgery, says MayoClinic.com.
Risks of Complications
Cataract surgery has risks of complications. Infection or bleeding may occur in some people, says The Foundation of the American Academy of Ophthalmology. Vision loss or decreased vision may occur, as well as an increased risk for retinal detachments. Doctors can treat most complications successfully, though if you experience any symptoms or unusual changes, contact an eye doctor immediately.
