Viewpoints: What Surgeons Want You
to Know
Before You Choose Laser Eye Surgery...
We ask surgeons what you should consider first.
By Liz Segre
It's like a miracle: one day you're wearing glasses, and
the next day you don't need them anymore! No wonder so many
people are considering refractive surgery to correct their
nearsightedness, farsightedness, and astigmatism.
But just like any surgery, it's serious business. If you're
thinking about it, first consider these important issues
that two eye surgeons shared with us in recent interviews:
Should You Believe the Ads?
One reason that refractive surgery is being talked about
so much is, you can't turn on a radio without hearing an
ad for it. Not that there's anything wrong with advertising.
Most surgeons and medical centers are doing a good job of
educating the public about LASIK, PRK, corneal ring implantation,
and the various lasers and other machines used in the surgery.
Radio and print ads are the first step, but these centers
also have detailed brochures and videos that tell you exactly
how they plan to correct your vision problems.
But don't assume too much from advertising, says Penny
Asbell, M.D., Professor of Ophthalmology at Mount Sinai
School of Medicine and Director of the Cornea Service and
Refractive Surgery Center in New York. "Just because
someone is advertising," she says, "it doesn't
necessarily mean they're more qualified."
Dr. Asbell, who is a refractive surgeon herself, recommends
asking the surgeon if he or she is associated with an academic
medical center, such as a teaching hospital or one that
is well known for advanced technology.
"Those who work in or are at least associated with
academic medical centers are more likely to keep up with
current information," she explains. "They are
more likely to have more constant exposure to new things
and to issues related to new procedures, than if they are
related to an (albeit busy) isolated office setting with
little contact with the academic world."
"A lot of companies make LASIK sound like it's a flap-and-zap
commodity. But the truth is, it's surgery," comments
Dr. Steve Updegraff, medical director of Updegraff Lasik
Vision in Tampa Bay, Fla. He recommends choosing a doctor
who is a Fellow of the American College of Surgeons. "The
credentialing process there is pretty steep; also, that
group is diligent about advancing the field of surgery."
Watch out for misleading advertising claims, Dr. Updegraff
adds. "If someone says he's been using a laser for
15 years, don't accept that - he's probably talking about
another type of laser or procedure, because LASIK hasn't
been around that long."
The Personal Touch
"As with any relationship you have with someone in
the medical profession, it has to be one of trust,"
says Dr. Asbell. "You have to feel that you trust the
person and that they're personally interested in you."
She adds, "If you can't develop that rapport, I would
be concerned. If everything goes well, you probably won't
have to see that person too often, and that's the end of
it. But if for any reason you're not happy with the quality
of the result, or there's any issue with healing that's
going to require more attention, you want to know that you
have someone who is personally connected to you and is working
hard to address your concerns - someone who isn't just running
a mill where they don't even remember who you are."
Dr. Asbell stresses that you should expect complete honesty
from a surgeon, and Dr. Updegraff agrees: "Be very,
very specific as far as what you ask the doctor," he
says. "Be like a good reporter - don't accept vague
information. If a doctor doesn't answer your questions fully,
leave and go somewhere else."
What Could Go Wrong
Inexperienced Surgeons. In laser surgery, says Dr. Updegraff,
"the laser is just a surgical tool. If you don't have
a good surgeon, you can have the most precise laser in the
world and still get poor results. We've seen a plethora
of doctors who are generalists that go through a short training
course and then go home and start cutting." As one
of the early investigators of LASIK, Dr. Updegraff has performed
more than 7,000 procedures. But he says he's still learning
new things.
In the past year, he says, "I've noticed an increase
in complex cases being referred to me. I'm seeing patients
with corneal flaps that were cut irregularly or too thin;
or the cases weren't managed very well, and the patient
may need a corneal transplant in order to see better."
Dr. Updegraff says that when something goes wrong during
the flap-cutting stage of LASIK, some less experienced surgeons
may go ahead and perform the laser ablation (tissue removal)
anyway, instead of stopping surgery and trying again at
a later date. He says this is one reason for poor results.
Patients Who Aren't Ideal Candidates. Another problem has
to do with physiology. "There is a subset of patients
who have weak epithelial attachments [which connect the
outer layer of the cornea to underlying corneal tissue],"
he comments. "They may show no signs of it pre-op,
and you don't discover it until during surgery. If that
happens, you need to stop and maybe do PRK [a laser-only
procedure] at a later time."
Unfamiliarity with Cutting Tool. In LASIK, Dr. Updegraff
believes it's worthwhile to ask if the surgeon owns the
microkeratome that will be used to cut the flap. If a surgeon
uses various microkeratomes, there may be nuances about
the way each one operates or feels in the hand that could
affect performance. He also prefers to use disposable microkeratome
blades just once, because with each use they become duller.
Side Effects. A common side effect of LASIK and PRK is
seeing glare, starbursts, and/or halos for a few days, especially
when looking at lights during nighttime. However, says Dr.
Updegraff, this usually diminishes or disappears altogether.
If it doesn't, surgeons may want to retreat the eye, which
isn't that unusual. "But too much redoing can lead
to hyperopia [farsightedness]," he says.
Glare is more likely to occur in people who have very large
pupils, as well as people who must do exacting work in low
light or at night. "We can look at the pupil with infrared
to see how much it dilates. Many times we screen athletes
who must perform under different lighting conditions, such
as bright stadium lights," says Dr. Updegraff.
Finally, dry eye is a common occurrence. "The corneal
nerves are severed when we make the flap in LASIK,"
says Dr. Updegraff. "The nerves in the cornea sense
dryness, so when that feedback loop is disconnected, patients'
eyes get dry but they don't feel it. The reestablishment
of the tear film and re-enervation of the cornea takes some
time, so patients with dry eye need an aggressive lubricant
program after surgery." In fact, if you have chronically
dry eyes, you may not be a good candidate for refractive
surgery at all, since dryness interferes with healing.
Post-Op Injury. Be very careful not to traumatize the eye
after surgery. Dr. Updegraff has several patients who are
professional athletes, and he recommends that they wear
a face mask or other protection for the first year so they
won't be hit in the eye. And airbags can be especially dangerous
to eyes after surgery.
How Refractive Surgery Can Make
Life Safer
The purpose of this article is not to scare you, but rather
to make you think. Despite their words of warning, Dr. Updegraff
and Dr. Asbell are strong proponents of refractive surgery
- both perform it often and have seen many patients who
are very satisfied with their new vision.
In fact, some of Dr. Updegraff's patients are leading safer
lives after their surgery. "Mark Royals [of the Tampa
Bay Buccaneers] is seeing things in the field that he never
saw before with his contacts, so for him, that's added safety,"
he says. "And [powerboat racer] Michael Allweiss was
very blind without his glasses. He also had contact lenses
blow out of his eyes while racing. So his surgery made all
the difference."
To sum up, the decision to proceed with refractive surgery
should be based on a careful weighing of pros and cons.
As Dr. Updegraff says, "These are your eyes, and you
are your own best advocate."
