Los Angeles Lasik Surgeon
Laser vision correction uses pulses of invisible, ultraviolet light
to remove a microscopic layer from the front surface of the eye,
changing the curvature of the cornea ever so slightly. To correct
nearsightedness, the curvature of the cornea must be decreased --
the cornea must be made flatter. To correct farsightedness, the
curvature of the central cornea must be increased, which is
accomplished by removing a donut shaped ring of tissue. To correct
astigmatism, the curvature must be altered in one specific
direction.
Only a very small amount of material is removed, usually less than
the thickness of a hair. Low amounts of nearsightedness,
farsightedness, or astigmatisim will require
smaller amounts of tissue removal, and larger corrections will
require greater amounts. The total treatment usually takes less than
one minute of actual laser time.
For patients with extremely dry eyes, thin corneas, large pupils,
very high corrections or a combination of these, Lasik without a
flap may be the best treatment. Rather than making a protective
flap, the laser treatment is applied directly under the soft
material (known as the epithelium) that covers the front surface of
the eye. There are many minor variations in how the soft material is
handled: if the soft material is completely removed, then the
procedure is called PRK (photorefractive keratectomy); if it is
replaced, the technique is called Lasek; if the soft material is
loosened with a machine, then it is called Epi-Lasik. In any of
these methods, the soft material heals in 5-7 days, during which
time the vision is blurry and a protective contact lens must be
worn. Sometimes both eyes are treated at the same time, though
sometimes the eyes are treated 2-4 weeks apart.

Maloney Vision Institute
During LASIK, a thin layer of tissue is folded back from the surface
of the cornea. After the laser reshapes the cornea, the tissue is
folded back into place, where it bonds quickly. At the Maloney
Vision Institute, we use a state-of-the-art, VISX S4 eye-tracking
laser-flying spot laser that produces an exceptionally smooth
treatment. This three-minute procedure requires no needles and no
stitches.
These procedures are similar to LASIK, except that a tissue flap is
not created. The laser treatment is done on the surface of the eye
after removing the outer layer of cells. LASEK and PRK are suitable
for people whose corneas are too thin or too curved to be good
candidates for standard LASIK. With LASEK and PRK, healing time is
slightly longer than with LASIK, and good vision is achieved in four
to seven days.
Dr. Maloney has had many years of clinical experience correcting the
vision of thousands of patients using a variety of techniques, and
has personally performed over 45,000 LASIK procedures.
Dr. Devgan has more than 10 years of experience in performing the
full spectrum of eye surgery, including LASIK, Cataract Surgery, and
Implantable Contact Lenses.

Laser In-Situ Keratomileusis (LASIK) LADARVision® CustomCornea®
system or the VISX Laser system or the Wavelight Alegretto laser
involves creating a precise thin
superficial flap with the Intralase femtosecond laser. The flap is
raised, and an ablation is performed to reshape the cornea with the
aid of an eye tracker with the excimer
laser, centered on the pupillary area. The flap is then replaced
without sutures. The entire procedure is performed under topical
anesthesia as an outpatient procedure.
The Intralase system creates a corneal flap of a precise thickness
and diameter with a lower suction level than a standard
microkeratome without using a blade. this makes
creating a flap safer than standard microkeratomes using higher
suction and blades.
Intralase presents proprietary femtosecond laser technology that
will enable patients to choose vision correction surgery with
confidence. The Intralase Pulsion™ FS Laser
offers refractive surgeons and incomparable safety platform, optimal
precision and total control as the only All-Laser alternative to the
mechanical microkeratome.
Wavefront based treatment measures not only the patient's glasses
prescription (lower order aberration) but also measures other
aberrations (higher order aberrations) which are present to varying
degrees in all eyes, even the 20'20 eyes of pilots.
The wavefront provides a unique "finger print" of the eye which is
different for each patient even if they have the same glasses
prescription. Conventional laser vision
correction often significantly increases these higher order
aberrations which can affect the quality of night vision and
contrast sensitivity. Wavefront based treatments attempt
to reduce or minimize any increase in higher order aberrations by
inputting the wavefront measurements into the laser to be used for
the laser vision correction. In
conventional laser vision surgery, only the patient's prescription
is entered into the laser.
