The time to undergo cataract removal is based on several factors. When a cataract starts to limit the activities and normal activities of a patient, it is time to start talking about correcting the cataract. For some individuals, such as airline pilots, even the slightest decrease in vision may indicate time for surgical intervention. Others can safely wait for further progression before undergoing surgery. Typically, vision less than 20/40 will cause significant challenges to most activities of daily living. Safety must always be considered. Many states have strict legal driving guidelines, and when a person’s vision falls below these limits due to cataracts, it is time for cataract surgery. During your yearly eye exam, your ophthalmologist should be able to help you decide if cataract surgery is right for your current condition.
