Advantages of same-day cataract surgery on both eyes include fewer office visits, faster recovery of binocular vision for driving and other critical tasks, and a quicker return to normal living. Simultaneous bilateral cataract surgery may be particularly helpful for people with cataracts in both eyes who are very nearsighted or very farsighted. These patients sometimes are unhappy when the cataract procedures are performed on separate days because they feel visually unbalanced after the first surgery.
