Some patients experience glare, halos, dry eyes, and at times, a mild fluctuation of vision. This can occur during the first few days or even weeks after a LASIK surgery. However, most of these side effects will subside and resolve with time. Severe side effects such as corneal flap complications and corneal infections are very rare. If you experience any eye redness, pain, or vision loss after LASIK surgery, please inform your doctor immediately.
