LASIK
LASIK corrects vision problems like nearsightedness, farsightedness,
and astigmatism by changing the shape of the outer layer of
your eye (the cornea). Changing the shape of the cornea allows
light entering the eye to be properly focused so that you
see more clearly.
Including prep time, you will only spend about an hour in
our office on the day of your LASIK eye surgery. If you are
nervous, we may give you a sedative medicine to help put you
at ease. Your eye is then numbed with anesthetic eye drops,
and a special device called a speculum is used to hold your
eye open. A suction ring is then placed over your eye.
To begin your LASIK laser eye surgery, we then use a special
instrument called a microkeratome to create a thin flap in
your cornea. After the flap is made, the suction ring is taken
off your eye and you are asked to stare at one place while
the laser works. The laser removes tissue from beneath the
flap so that the shape of the eye is changed. Once your cornea
achieves the proper curvature, the flap is laid carefully
back over your eye. It heals there without stitches. We will
give you an eye shield and allow you to go home. After your
LASIK laser eye surgery you will return for a check-up within
twenty-four hours and at prescribed intervals thereafter.
Description of Laser Technology:
Bausch and Lomb
Many lasers only treat an area of 6-8 mm with virtually no
smoothing of the edges. This can result in vision difficulties
at night or under other low light conditions when the pupil
can grow to as much as twice its normal size. The pupil will
extend beyond the treatment zone, resulting in glare and haloes.
The Bausch
and Lomb laser eliminates this problem by offering the
widest treatment zone available for LASIK. In addition, the
laser creates a blend zone that allows the doctor to smooth
the corrected area into the rest of the cornea, maintaining
a spherical shape.
Many excimer lasers use a broad beam that leaves the outer
edges of the corrected area too angular, creating the likelihood
of glare and haloes. This LASIK technology can be refined
by splitting the single broad beam into seven smaller beams
that rotate around the treatment area, much like a showerhead
splits a single water stream into smaller streams. However,
even these smaller beams may not achieve smooth, well-rounded
edges.
The Bausch and Lomb laser beam moves across the cornea carefully
correcting and blending the treatment area. The LASIK laser
eye surgeon uses the laser's rapid pattern to create the desired
correction, blending the treated area smoothly into the surrounding
cornea for an unmatched final result. Safely. Comfortably.
The final result is a very smooth surface with no steep angles
or edges. This helps maintain the cornea's natural shape and
reduces the risk of post op visual glare and haloes. (Poor
night vision results such as glare and haloes have been reported
by some patients after the LASIK procedure. The Bausch and
Lomb laser can reduce the potential for glare and haloes under
low light conditions.)
Bausch and Lomb. The company long known and recognized for
leadership in quality of vision and innovation provides the
leading technology used in the field of laser eye surgery,
including the worldwide gold standard ORBSCAN corneal mapping
system, Hansatome microkeratome, — all available at
I-Surgeons.
Nidek
Nidek's Excimer Laser EC-5000 is designed to reshape the cornea
for PRK, PRK of moderate myopia with astigmatism (consecutive
correction of myopia and astigmatism), PTK and LASIK.
Key Features
- Dynamic Rotating and Overlapping
Delivery System —
Designed to perform refractive and therapeutic treatments
over a large ablation area.
- Easy and Effective Alignment System
—
3D motorized joystick along with improved illumination and
aiming beams provide precise control of laser beam delivery
arm.
- Computerized Performance —
Laser delivery parameters are automatically calculated by
entering the basic data.
During the ablation procedure, the computer monitors the
system parameters continuously.
Visx
The VISX offers variable spot beam technology — it adjusts
the laser beam size according to the treatment, minimizing
corneal tissue removal. This also allows for quicker treatment
times that are typically between 10 to 40 seconds.
It also provides a larger treatment, or ablation, zone. Scanning
technology adds a blend zone that allows the treatment on
the cornea to be extended to 8 mm which may help reduce the
risk of night vision symptoms such as glare and haloes.
The VISX removes the least amount of corneal tissue of any
laser available, making it the laser of choice for LASIK laser
eye surgery patients with thinner corneas.
PRK
The precursor to LASIK, PRK first appeared in 1987. Like LASIK,
PRK uses an Excimer laser to reshape the cornea. However,
PRK works directly on the outer surface of the cornea. PRK
can correct myopia, astigmatism and, to a lesser degree, hyperopia.
ENHANCEMENTS
Some patients may require additional surgery at a later date.
This may be due to the development of an additional refractive
error over time. Our surgeons will let you know if another
treatment is required during your post-surgical follow-ups.
