LASIK.
Late postoperative complications
The incidence of epithelial ingrowth has been estimated at 0.1%.
Glare is another commonly reportedly 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.
Newer equipment is available to properly treat those with large pupils,
and responsible physicians will check for them during examination.
