Avoid rubbing your eyes for at least the first week after LASIK surgery. The corneal flap cut out during the surgery requires substantial time to heal. Unnecessary rubbing may inadvertently aggravate the wound. You should also take extreme caution to avoid soap, hair spray or shaving lotion from entering your eyes. The eye surgeon will typically provide you with a postoperative kit, which may include a set of eye shields/goggles. Wear them while you are sleeping, at least for the first three nights after surgery.
For at least a week after LASIK, prevent water from entering your eyes, since water hinders the natural clotting mechanism, and therefore might delay the healing process of the cornea. You must also cancel any swimming plans for a minimum of 10 days following LASIK. You must not wear eye makeup for at least one week after LASIK.
Contact sports are to be avoided for at least a week or so following surgery. Furthermore, it is advised that you wear some kind of protection gear for your eyes for a period of a month, even after resuming exercise and other sporting activities. Bright sunlight may lead to scarring, and therefore, sunglasses are recommended on bright days until the cornea heals.
To summarize, though you will able to resume your usual lifestyle within a week or so after LASIK surgery, it is crucial that you protect your eyes to prevent injury or infection. And since the corneal flap does not heal instantly after surgery, you must prevent washing your eyes for at least a few days after surgery.
