LASIK is performed utilizing the excimer laser, however, unlike PRK,
the surface skin cells are not removed. Instead, a thin flap is
created and retracted out of the way during the laser portion of the
surgery. Once the excimer laser has reshaped the cornea, the flap is
repositioned and naturally stays in place. Because the surface cells
have not been removed, there is typically little, if any,
post-operative pain as compared to PRK and vision tends to improve
relatively quickly. The convenience of LASIK (due to the quicker
visual recovery and lack of post-operative pain) is what has made it
a popular option for many patients. The need to create a corneal
flap, however, adds a slightly increased risk to the surgery, and
therefore some patients may be better served with PRK as opposed to
LASIK.
There are a number of factors that doctors must evaluate before they
can determine who is eligible for LASIK. Some doctors deem certain
pre-existing conditions to be contraindications to the procedure and
will not perform surgery if you possess them. Other conditions may
complicate the surgery and increase your risk of having
post-operative problems. Patients with these conditions need to have
a thorough conversation with their doctors regarding eligibility and
expectation levels.
The procedures are not painful during the surgery itself. A vast
majority of patients experience little, if any, pain following LASIK
surgery. The response following PRK varies with every patient. Some
feel a mild irritation similar to an eyelash in the eye, while
others feel that the pain is more significant and require pain
medication for 1 to 2 days following the surgery. PRK tends to
provide a slower visual recovery as compared to LASIK. Following PRK
the vision will be blurred for two to four days and will slowly
improve for the next one to two weeks before reaching a stable
endpoint.
LASIK improves the uncorrected vision-one's visual capacity while
not wearing corrective lenses-in most patients who have the
procedure. Over 90% of patients with low to moderate myopia achieve
20/40 or better vision (the level most states and provinces require
for driving without glasses or contact lenses). Many patients can
also expect to see better than 20/40 uncorrected. Some studies show
that approximately 70% of patients may achieve 20/25 or better
uncorrected visual acuity following surgery.Remember, however, that
there are no guarantees that you will have perfect vision, and
patients with high myopia (more than -7D) and high hyperopia (more
than +4D) should have lower expectations. People who are most
satisfied with the results of laser correction clearly understand
the potential risks and complications of the surgery and possess
realistic expectations of what their vision will be like following
surgery.

LASIK or Laser in-Situ Keratornileusis treats refractive errors by
removing corneal tissue beneath the surface of the cornea. This
procedure combines the accuracy of the excimer laser with the
benefits of Lamellar Keratoplasty (LK). LK has been performed on a
limited basis since 1949 to correct higher levels of nearsightedness
and moderate amounts of farsightedness. More recently, LK was
refined by technological advancements of an instrument called a
microkeratome or more recently a laser (IntraLase) that allows the
surgeon to fold back a thin corneal layer of cornea. A second pass
of the microkeratome was required to remove tissue from the inner
cornea. However, the quality and accuracy of this second pass could
not always be achieved.
Boston PRK is performed by Dr Ernest Kornmehl, a refractive surgery
specialist. On this webpage, Dr Kornmehl provides information about
PRK refractive surgery and how it has improved the vision of many of
his patients. PRK or Photo-Refractive Keratectomy treats refractive
errors by removing tissue from the surface of the cornea. First,
your eye is numbed using a topical eye drop anesthesia. Then, the
surgeon removes the epithelium, a thin layer of protective skin that
covers the cornea. This may be done with either a blade, a brush or
even the excimer laser. During the actual procedure, the patient
stares at a fixation light. In less than a minute, the laser removes
the proper amount of tissue while it reshapes the surface of the
cornea.

Boston LASIK Eye Surgery
LASIK is the most frequently performed procedure used today to
reduce or eliminate the use of glasses or contact lenses. LASIK
(Laser In-situ Keratomileusis) involves using an excimer laser to
reshape the cornea and help restore vision compromised by
nearsightedness, farsightedness, and astigmatism. For clear vision
to occur, light rays must pass through several structures, including
the cornea, and focus directly on the retina. If the cornea is too
steep or too flat in relation to the length of the eye, light rays
will focus in front of the retina (myopia) or behind the retina (hyperopia).
If the cornea is curved unevenly, there will be two or more focal
points, resulting in blurred vision (astigmatism).
During the LASIK procedure, a flap is created in the outer layers of
the cornea, using either the IntraLase FS Laser or a microsurgical
instrument called a microkeratome. The reshaping of the cornea with
the excimer laser is performed under this protective layer of
corneal tissue. Once this flap is created, the flap is gently folded
back, exposing the underlying cornea. The cool beam of the excimer
laser is then used to remove microscopic layers of tissue and
precisely sculpt the exposed cornea to correct your refractive
error.
The Allegretto Wave is the fastest excimer laser system available in
the United States today. The Allegretto Wave incorporates wavefront
principles into each procedure, while adjusting the treatment to
your unique corneal curvature. The Allegretto Wave’s wavefront
optimized treatment profile specifically addresses spherical
distortions to improve the quality of night vision, depth
perception, and contrast sensitivity. "Perfect Pulse Technology"
accurately controls the energy level and exact placement of every
laser pulse as it reaches the eye. The high speed active eye-tracker
follows even the fastest eye movements during treatment. The
Allegretto Wave provides superior clinical results.
Dr. Violin has been the subject of many news articles concerning his
expertise in the areas of laser vision correction and cataract
surgery. He has been featured, and has appeared as a guest speaker,
on numerous local television and radio broadcasts, where he has
discussed state of the art technologies in both of these areas.
Graduated from Columbia University College of Physicians and
Surgeons in 1967 and completed his ophthalmic residency at
Massachusetts Eye and Ear Infirmary. He was one of the pioneers in
small incision cataract and implant surgery in Massachusetts and has
had experience in this area for almost a quarter of a century.

Laser in-situ keratomileusis (LASIK) is the most popular of all the
refractive surgery procedures today. A device called a microkeratome
creates a flap in the cornea. Once the flap is lifted, an excimer
laser reshapes the cornea. Dr. Keamy uses the VISX S4 laser with an
eye tracker. Afterwards the flap is placed back into position. The
LASIK technique has a relatively quick recovery with functional
vision within only a few days. It is relatively painless. Most
patients are quite happy with their results however the surgery is
not without risk nor are the results guaranteed. Sometimes an
enhancement or second surgery must be done to achieve optimal
results. The procedure is approved for low to high myopia, low to
moderate hyperopia, and astigmatism.
LASIK is performed on an outpatient basis in Dr. Keamy's office and
takes only a few minutes. You will remain awake during the procedure
and the only anesthetic you will need is eye drops. Afterwards you
will use both steroid and antibiotic drops for one week. Anticipate
being in our office about one hour on the day of the procedure. Most
patients experience improved vision the same day and are able to
return to work the very next day.
CK is an exciting new advancement in vision correction because it
uses radiofrequency (RF) energy instead of a laser to reshape your
cornea. CK can change how the eye focuses light by reshaping the
surface of your eye (cornea). When the shape is changed, light can
be refocused on the correct part of your eye (retina). To produce
this reshaping, CK uses the controlled release of RF energy to heat
and shrink corneal tissue. This steepens the cornea and allows light
to properly focus on the retina again.
Dr. Jean E. Keamy’s medical degree was the final chapter in a number
of extensive academic achievements. After graduating with a B.A. in
Molecular Biology from Princeton University, Dr. Keamy pursued
graduate studies at the M.I.T. Sloan School of Management and then
completed her M.B.A at the New York University Leonard N. Stern
School of Business Administration. After working several years on
Madison Avenue, Dr. Keamy felt that her management job had no impact
on helping people.
