Deciding whether to have cataract surgery
Immediate removal of a cataract is rarely necessary. Instead, the decision of when to have the surgery almost always rests with the patient. The decision is based on the cataract's interference with day-to-day activities like reading and driving, the balance between the operation's benefits and risks, and the presence of other health conditions that might affect the outcome. In some cases, people with another major vision disorder, such as advanced glaucoma or age-related macular degeneration, may be discouraged from having cataract surgery because it may not improve their vision. On the other hand, cataract removal might benefit people with certain types of retinal damage.
