The cause of dry eye after eye surgery

Performing laser eye surgery usually causes changes in the level of the cornea. Usually, these changes can disrupt the functioning of the cornea and cause dry eye. It’s best to know that a person is more likely to have eye dryness than other eye surgery procedures after performing LASIK. In fact, in the LASIK operation, the lining of the cornea is thin, the specific nerves at the cornea are temporarily cut off, which reduces the sense of the cornea and thus leads to dry eyes. Under normal conditions, this damaged nerve is restored and the cornea is restored again. However, it may take more time for some people who have a dry eye condition.
