Possible risks

3% of patients report slight blurring. 10% see haloes around light sources. In most cases these symptoms disappear after 6 months.

In rare cases, abnormal corneal scarring (haze) may develop, affecting visual acuity and generating troublesome reflections. This area may be re-treated but not earlier than 6 months following the initial surgery. In less than 1% of cases the scar re-forms, remains resistant to all correction and permanently affects the vision.
