PRK is an abbreviation for Photorefractive Keratectomy. PRK is a vision
correction procedure which uses a laser to reshape the cornea. PRK takes
just a few minutes and is done under topical anesthesia.
Who is a candidate for PRK?
Patients whose corneas are too thin for LASIK.
Athletes who may have a possibility for eye trauma.
Patients who may have a physically active lifestyle.
Patients with certain corneal diseases.
Patients with a certain degree of dry eyes.
Patients concerned about a corneal flap.
Patients with large pupils.
Patients with thin corneas.
Patients who had previous eye surgery, such as RK, LASEK or
What is the difference between PRK, LASEK and LASIK?
LASIK, LASEK and PRK treat nearsightedness,
farsightedness, and astigmatism, but if you have have larger pupils or
thin corneas, PRK may be the best procedure for you.
Will I need reading glasses after my surgery?
Generally, patients under the age of 40 still read
well without the use of glasses following the surgery. Patients over the
age of 40 may need reading glasses for small print. Presbyopia is a
term that refers to the natural weakening of the muscles that occurs in
our early to mid 40s, causing us to need reading glasses. LASIK does not
correct or prevent presbyopia. Should you fall into this age category,
we will be happy to discuss monovision with you at your consultation.
This is an option that allows many patients the convenience of near and
distance vision without the use of reading glasses.

Once your vision allows, you can resume all activities. You
should however, avoid intense or direct strong sunlight and
dirty or dusty environments for as long as possible after
How soon can I drive after PRK?
We will require that you have someone drive you home
following your procedure. However, you may drive when you
feel comfortable enough to drive safely, possibly the next
Do I have to avoid all activities post-operatively?
No. We typically demonstrate to the patients that they can
bend over immediately after surgery, pick up 20-30 pounds,
and shower, provided they don't get water into their
operative eye. We do ask that they wear an eye shield at
bedtime for the first few weeks after surgery so they do not
inadvertently rub the eye during sleep. Typical follow-up
evaluations are scheduled at 1 day, 1 week, 3 weeks, and 6
weeks, with glasses being prescribed between the 3rd and 6th
Why cant I wear my contact lens wear before my preoperative exam?
Contact lenses can change the shape of your cornea
similar to how a watchband can make an imprint on your wrist. If you
have your eyes examined too soon after removing your contact lenses,
several of the eye tests could give inaccurate results and negatively
influence your surgical outcome. Discontinue wearing soft contact lenses
the doctor's recommendation prior to the preoperative measurements
and surgery. Rigid gas permeable (RGP) contact lens wearers may require a
more protracted amount of time out of lens wear.
Our Doctor will advise you if your corneas have not returned to
their natural shape after removing your contact lenses.
Will I still need glasses or contact lenses?
You may need glasses or other corrective lenses after the
procedure on a temporary or permanent basis.
What if I had a
previous corneal transplant or radial keratotomy?
has shown that PRK can be successfully performed after
a corneal transplant or previous radial keratotomy (RK)
refractive surgery. However, the decision depends on
many factors. See us for a
pre-operative consultation and exam to see if you are a
