LASEK
is a relatively new refractive procedure that is similar
to LASIK. It combines elements of PRK and LASIK to treat
low to high levels of nearsightedness, farsightedness and
astigmatism, and may offer some advantages over both. LASEK,
PRK, and LASIK are performed in our Cincinnati offices.

LASEK
is best suited for risk adverse patients. With LASEK,
no microkeratome is used and only the very top layer
of the cornea (epithelium) is used to make a protective
corneal flap. Unlike in PRK, the epithelium is not
removed in LASEK. The surgeon uses the excimer
laser to reshape the cornea and correct your refractive
error. Your surgeon may decide that LASEK is
a better option for you, especially if your eyes are
be too dry or your corneas that are too thin for LASIK.
Based on the individual situation, your eye surgeon
at Halpin Eye Center will recommend the surgery option
that best suits your needs. |

LASEK
is for those who:
• want to reduce or eliminate their dependence
on glasses or contacts
• are over 18 years of age
• are nearsighted, farsighted or have astigmatism
• have had a stable eye prescription for at
least one year
• have no health issues affecting their eyes
• have wide pupils
• have corneas too thin for LASIK
• who do not want LASIK because it requires
a microkeratome
What to Expect on Surgery Day
You will arrive at the laser center about an hour prior
to your procedure. Once you have been checked-in and settled
comfortably, you will be prepared for surgery. The area
around your eyes will be cleaned and a sterile drape will
be applied. You may be given a sedative to help you relax.
Eye drops will be used to numb your eyes; no injections
or needles are used. When your eye is completely numb, an
eyelid holder will be placed between your eyelids to keep
you from blinking. Next, a specially designed instrument
will be placed on your eye around the area that will have
the laser applied. Then a diluted alcohol solution will
be placed in the instrument, which loosens the epithelium
from the surface of the cornea. The epithelium is then pushed
to the side.
You will be asked to look directly at a target light while
the laser reshapes your cornea. The laser will be programmed
with the information gathered in your pre-operative exam.
The laser treatment will be completed in less than a minute
or two, depending on the amount of correction needed. To
finish the procedure, the surgeon will smooth the flap back
into place. A temporary bandage contact lens will be used
to keep the epithelium in place and reduce post-operative
discomfort. |
Expectations
after LASEK
Following your procedure, your eye(s) may be shielded
for protection. Your vision will probably be a little
blurry at first, so someone will need to drive you
home. You should relax for the rest of the day. You
may experience mild to moderate discomfort for two
or three days. You will be given instructions on how
to manage this discomfort before you leave. Most patients
resume normal activities within two to three days.
Vision can fluctuate for up to six months.

After
LASEK, you may experience some visual side effects. These
visual side effects are usually mild and most often diminish
over a few days to a few weeks. But there is a slight chance
that some of these side effects won't go away completely,
such as feelings of dryness, glare and halos. |
