Can glare and halos and be prevented?
There is very little risk associated with laser vision correction. Some patients may experience temporary symptoms, but only a small percentage will have long-term side effects. The most common side effects are problems with night vision, including halos and glare. There are several possible causes for halos and glare following laser eye surgery: If your refractive error was not completely corrected during your first laser eye surgery, you may still have low levels of nearsightedness, farsightedness, or astigmatism. This can be remedied with a revisional “touch-up” surgery to further correct the shape of your cornea. When pupils dilate beyond the perimeter of the treatment area during laser eye surgery, this sometimes results in compromised vision in low light conditions (when the pupils are completely dilated). In order to prevent this from occurring, our LASIK surgeons measure pupil size at full dilation prior to laser eye surgery. This allows us to determine whether or not we can tr
