Laser Eye Surgery - Late postoperative complications

* The incidence of epithelial ingrowth has been estimated at 0.1%.

* Glare is another commonly reported complication of those who have had LASIK.

* 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. 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.

* Dry eye or in severe cases Chronic Dry eye. Due to nerves that are severed during the Lasik operation (around 70% of corneal nerves are severed), the lubrication system of the eye is affected and nerves may never recover to pre-operative condition. This may leave the patient with potential permanent dry eyes.
