A: Potential undesirable side effects include dry eyes, problems with night vision and halos or ghosting of vision. Most of these symptoms will clear in weeks or months and some patients say that the night vision or halos are no worse than they experienced with their contact lenses. For reasons that are not completely understood, the eyes are drier than normal for up to six months after LASIK. This is, of course, more of a problem in our high and dry climate, requiring frequent use of lubricating drops and sometimes temporary plugs to keep the eyes better lubricated. Other less common side effects are explained during our preoperative patient education.
