The time between surgeries depends on the results of the first eye and varies from surgeon to surgeon. If endophthalmitis is to occur, it will most likely do so in the first two weeks. Therefore, I usually do not recommend surgery on the second eye until at least two weeks after the first eye surgery is performed. If small incision phacoemulsification cataract surgery is performed, it is usually reasonable to operate on the second eye two to six weeks after the first. However, there are some occasions where bilateral cataract surgery may be the better choice.
Most patients see well enough to drive without glasses after surgery.
However, there is no guarantee that glasses will not be necessary after cataract surgery. It is more likely that you will need reading glasses than glasses for the distance. If glasses are required, they are usually very thin, not thick like the cataract glasses used before IOLs became available. Some patients have other factors that may limit the surgeon's abilities or options to provide distance vision without glasses. Patients who do not drive or who are not very active may desire reading ability without glasses instead of good distance vision without glasses.
