The precautions are fairly simple and would be similar to all irrespective of LASIK done. Patients can typically return to normal activity with a couple of days. The fear is of catching an eye infection. The first week after LASIK you will be on eye drops which are antibiotics so that aspect is anyways taken care of. However, some general and basic rules of hygiene such as not rubbing your eyes with unclean hands, carrying a hand sanitizer to keep the hands clean etc helps. We ask you to wear a pair of good UV protecting sunglasses when outdoors to protect your eyes from dust, strong sunlight and allergens. Only swimming underwater is to be avoided for at least one week. No eye makeup should be worn for at least one week. Light sensitivity may be increased, so a pair of comfortable sunglasses may be required.
