LASIK Eye Surgery
In the 1980s, IBM pioneered the precise excimer laser technology to
improve semiconductor capacity. An unexpected benefit was that the
specific ultraviolet wavelength emitted by the excimer laser was
ideal for reshaping corneal tissue with submicron precision.
By changing the shape of the corneal surface, the excimer laser is
used to correct refractive errors such as nearsightedness,
farsightedness, and astigmatism. Excimer lasers first entered FDA
clinical trials in the late 1980s. In the original clinical trials,
the lasers were only used on the surface of the eye in a procedure
called PRK. While PRK had excellent results and is still performed
today, removal of the surface cells of the cornea creates discomfort
and several days of blurry vision. In subsequent trials, the excimer
lasers were used to perform LASIK eye surgery, in which the corneal
laser treatment was placed beneath a corneal flap. Since the surface
of the eye is not disturbed, the speed of recovery is much more
rapid with minimal discomfort.
A prevalent myth regarding lasik surgery is that it is not a viable
alternative to contact lenses and glasses for people who possess
some level of refractive error. This could not be any further from
the truth. In other words, people who have conditions of
nearsightedness, farsightedness and astigmatism are often found to
be great candidates for refractive procedures as a means to clarify
their vision. In nearsightedness (myopia), the light rays of the eye
are bent too much. Lasik surgery flattens the cornea of the eye,
allowing the light rays to focus onto the retina. Farsightedness (hyperopia),
occurs when the light rays of your eye are bent too much. In
treating farsightedness with lasik surgery, the cornea is
“steepened” allowing for the light rays to pass through to the
retina. Astigmatism occurs when the light rays are not bent
simultaneously, providing for cloudy vision. Lasik surgery
alleviates astigmatism by making the cornea more round-like in shape
and allowing the light rays to pass in a uniform fashion.
Eye Doctors of Washington has the unique distinction of providing
the most advanced technologies in an academically oriented private
practice setting. Our research grants allow us to have the most
advanced diagnostic equipment including WaveScan™ aberrometers,
optic nerve analyzers, and specular microscopes. We provide a wide
spectrum of eye care, ranging from comprehensive general eye
examinations to highly specialized ophthalmologic care including
laser vision correction and other eye surgery treatments at our
Virginia, Maryland, and Washington, DC, area offices. Our locations
were chosen to be easily accessible by car, metro, or bus. We have
carefully designed our offices to make your visit both comfortable
and efficient.

Laser Vision Correction
At our vision correction practice in Columbia, Missouri, Dr. H. Kell
Yang offers CustomVue® LASIK eye surgery using the latest
technology. CustomVue® LASIK is a variation on the LASIK procedure
in which the ophthalmologic surgeon uses a state-of-the-art piece of
equipment called a WaveScan® Analyzer to create a detailed map of
the cornea. Using this map, the surgeon is able to more precisely
customize LASIK treatment to the unique visual aberrations of each
patient. LASIK is an outpatient procedure designed to reduce an
individual's dependence on glasses or contact lenses. After having
LASIK eye surgery, our patients often report feeling a sense of
freedom in being able to wake up every day to clearer vision.
LASEK, or laser assisted sub-epithelial keratomileusis, is similar
to PRK and LASIK eye surgery in that it involves reshaping the
cornea to correct refractive errors responsible for poor vision.
Unlike PRK, LASEK involves the creation of an epithelial flap. That
is, the surgeon creates a flap in the outer layer of the eye in
order to access the corneal tissue beneath. In this way, the
procedure is somewhat similar to LASIK; however, the LASEK flap is
much thinner than the LASIK flap and is produced using an alcohol
solution rather than a microkeratome or a laser. The creation of a
thinner flap reduces the risk of flap-related complications.
Dr. Yang is a native of Philadelphia, Pennsylvania, and has been
serving the mid-Missouri area as a board-certified ophthalmologist
for over 25 years. His specialties include cataract and refractive
surgery. Since 1980, Dr. Yang has performed thousands of
small-incision cataract surgeries (phacoemulsification). He first
performed refractive surgery in the early 1990s and LASIK when it
gained FDA approval, and he has since performed thousands of vision
correction procedures. At our practice in Columbia, Missouri,
patients benefit from Dr. Yang's extensive medical training and
personal approach to vision correction.

LASIK or Laser in Situ Keratomileusis is a procedure that offers
many advantages over other forms of laser vision correction because
it is performed under the corneal layer. As a result, there is less
surface area to heal, less post operative discomfort, less risk of
corneal haze, and vision returns more rapidly, usually within one
day or so.
The results of the Glaucoma Laser Trial (GLT) are encouraging
regarding the usefulness of Laser Trabeculoplasty (LT) as an initial
treatment for POAG. It appears that LT is at least as good if not
better than starting with medications, because in the short term, LT
provides good pressure control and has the advantage of postponing
and/or reducing the inconvenience, nuisance, and side effects
associated with taking medications.
The pressure-lowering effects of laser trabeculoplasty in Glaucoma
Laser Trial (GLT) patients with high Intraocular Pressure (IOP) and
not controlled by medicines encourages more frequent use of laser
trabeculoplasty.
Dr. Bogart received his medical training at Baylor College of
Medicine. He did his Internship at Tripler Army Medical Center in
Honolulu, Hawaii. His Residency in Ophthalmology was in Washington
D.C. at Walter Reed Army Medical Center.
Dr. Bogart has served his country in both the Army and the Air
Force. During the Vietnam Conflict he was a Helicopter Pilot. After
medical school he served as both a General Medical Officer (prior to
his residency training) and as Chief Ophthalmologist at Ft. Jackson,
South Carolina. He currently serves as a flight surgeon, & Lt. Col.
with the 169 Medical Squadron out of McEntire with the South
Carolina National Guard.
