Since your eyes are still recovering and are vulnerable to radioactive beams. Typically, it will take more than half a year before you are good to go, based on doctor's counseling.
Technically, you can do some computer work, watching TV, showering or bathing within a few hours of your surgery. But, your are actually not recommend to use computers in a short time after cataract surgery. You need give your eyes some time to heal. Personally, you'd better not use computer at least till two weeks latter. Take care.
