Your vision will be blurry for the first 6 hours. Most patients are able to resume most daily activities the very next day. We recommend rest of 1-2 days before returning to work.
It is not unusual for some patients to be able to drive or work on the computer on the day after LASIK. Looking at the computer and reading are unlikely to affect the healing of your vision. The most important things are to instill the eye drops as prescribed by the doctor and not to rub the eyes for the first month.
