Epi-LASIK, (Epithelial Laser In Situ Keratomileusis) is an advanced type of corneal surface ablation to correct nearsightedness, farsightedness and astigmatism. Like the other Laser Eye Surgery surface ablation procedures such as PRK and LASEK, it attempts to merge the desirable features of LASIK, PRK and LASEK.
In this procedure, a specially designed microkeratome like
instrument is used to create a thin flap of corneal epithelium.
It achieves this by gently separating the epithelium from the
underlying corneal layer without cutting. In Epi LASIK, no
alcohol solution is applied to loosen and remove the surface of
the epithelium as in LASEK.
for Patient Information Booklets
Advanced Epi-LASIK may be your best choice if you have
thin corneas or have certain conditions of the cornea.
Which procedure is best for you, will be ascertained
from your consultation.
Epi-LASIK is similar to LASEK in that it is a
LASIK Eye Surgery procedure that can be used for patients who
have thin corneas and might not otherwise be good candidates for
ordinary LASIK. Once the epithelial layer has been removed, the
Excimer Laser is then applied and reshapes the cornea to correct
your prescription, as in LASIK, PRK and LASIK. Upon completion
of the Excimer Laser application, the epithelial flap is then
returned to its original position.
Epi-LASIK has a relative advantage in that it
avoids any of the potential complications encountered while
making a conventional LASIK flap and during the flap healing
process. Compared to LASEK and PRK it is believed that Epi-LASIK
can allow a more rapid visual recovery, perhaps 3-4 days versus
a 7 days or more with PRK and 5-7 days with LASEK.
