There is no clear restriction on how long you can go out after cataract surgery, it is mainly recommended to stay in the ward for observation for one day after surgery, and go out after the bandage is removed. As most of the cataracts, except for some cases of trauma, are operated by cataract ultrasonic emulsification combined with IOL implantation, which has the characteristics of small surgical wounds, less trauma during the operation, and faster recovery after the operation, there is no strict restriction on going out after the operation, but it is suggested to stay in the hospital room one day after the operation for observation, and to deal with the problems in time. After cataract surgery, the eyes are in a more fragile state, so there should be some restrictions on the environment of outdoor activities, avoiding activities in dusty environments, and at the same time, follow the doctor’s instructions to use antibiotics and other drugs to prevent infection. It is recommended that patients go to the ophthalmology department of a regular hospital for consultation and treatment as prescribed by the doctor.
