The third complication is
in the flap-bed interface following LASIK. Sometimes, there can
be inflammation in the interface, leading to a drop in vision. Sometimes,
cells from the top surface of the flap (epithelium) migrate to the
interface and grow there. Most times, lifting the flap and washing,
can solve these problems. In rare cases, the flap may need to be
cut away (in which case, it becomes a PRK like procedure). In extremely
rare cases, a corneal transplant may become necessary.
Another complication of LASIK is kerastecsia, or a bulging forward
of the cornea due to excessive thinning. While we take care not
to excessively thin the cornea, in rare cases, it can be spontaneous.
This condition may lead to a severe drop in vision, and may be helped
by wearing hard contact lenses or a corneal transplant.
Another complications of LASIK include undercorrection or overcorrection
(which may require an enhancement procedure), glare or haloes around
lights, especially at night, dry eyes, and an increased sensitivity
to pain.
In rare cases, the flap may shear off due to trauma suffered even
several years after the procedure.

in our informed consent form, which you will be required to sign
before you undergo the procedure.
