Late postoperative complications

The incidence of epithelial ingrowth has been estimated at 0.1%.[23]Glare is another commonly reported complication of those who have had LASIK.[27]Halos or starbursts around bright lights at night are caused by the irregularity between the lasered part and the untouched part. It is not practical to perform the surgery so that it covers the width of the pupil at full dilation at night, and the pupil may expand so that light passes through the edge of the flap into the pupil.[28] In daytime, the pupil is smaller than the edge. Modern equipment is better suited to treat those with large pupils, and responsible physicians will check for them during examination.Late traumatic flap dislocations have been reported 1–7 years post-LASIK
