“Are there any side effects after laser eye surgery?”

Dry eye. Glare. Decreased night vision. And may need cataract surgery earlier like late 50s

You don't specify what kind of laser eye surgery you are referring to so I would assume you are talking about LASIK to correct your vision problem. Laser eye surgery is surgery so there are entire books written on the subject including possible complications, so there is not enough space here for a complete discussion.

common is laser vision surgery patients.
