About 20% of Dr. Andrew Holzman's patients are better PRK candidates than they are LASIK candidates. Generally, a patient will be deemed a PRK candidate at any of the TLC facilities in Virginia, Maryland, or Washington D.C. if they have thin corneas or if they are engaging in physical contact in their daily routine.
Some patients are only candidates for PRK. When we look at our patient
base, approximately 20% of the patients we see are candidates for PRK, and
the other 80% of the patients that we operate on are Lasik patients.
There are a variety of reasons why someone might be a better candidate for
PRK. The most important reason is usually corneal thickness. If the cornea
is not thick enough for us to make a Lasik flap, then we're going to opt
for PRK because it is a safer procedure for that particular patient. Also,
if the cornea has a curve in it that we deem to be less safe for us to make
that flap, again, in Lasik, then we will opt for PRK. Lastly, if the
cornea has a surface abnormality, we may also opt for PRK.
There are also certain occupations and hobbies, such as martial arts, which
lend themselves better for PRK. We do a lot of law enforcement with PRK,
and it's usually because of the fear of getting involved in a fight where
the face or the eyes may get hit or banged in the early post-operative
period, thereby causing some damage to the flap. For this reason, we opt
for PRK in these patients as well.
