The human
eye works very much like a camera. The cornea and internal lens focus or
refract light toward the retina, which is like film in the camera.
Oftentimes the refracting or focusing power of the cornea and lens is
not properly coordinated with the length of the eye. This is the usual
reason for astigmatism, myopia (nearsightedness), and hyperopia
(farsightedness).
Glasses and contact lenses had been the
traditional solution for refractive errors until refractive surgery
became popular in the early 1980s. LASIK is one option available to
treat low to high levels of nearsightedness, farsightedness, and
astigmatism. Millions of people worldwide have been treated, thus
reducing or eliminating their dependence on glasses and contact lenses.
In fact, more than 94 percent see well enough to drive without glasses.
People can more freely pursue their hobbies, sports activities, or
career options.
LASIK (IntraLase or iLASIK) surgery consists of
two steps. During step one the physician creates a corneal flap. The
femtosecond laser creates the flap by accurate application of energy
within the cornea. NASA astronauts and U.S. pilots can have laser vision
correction surgery today because of the exclusive, validated safety and
precision performance of the IntraLase Method. With the latest
femtosecond laser, the iFS laser, patients experience faster visual
recovery, fewer dry eye symptoms, and maximum flap stability. During
step two, the flap is folded back and a second laser, the excimer laser,
applies a cool beam of invisible light which precisely vaporizes tissue
and alters the shape of the cornea. The flap is then laid back in place
and adheres by natural means. Eye drop medications are used in the
first postoperative week, and lubricants may be necessary in the first
few months. The procedure takes 5–15 minutes and most people resume
their normal activities the next day.
If you are over the age of
18, are nearsighted, farsighted or have astigmatism and have stable
vision, you may be a candidate for this state-of-the-art procedure.
However, only a physician may make that final determination. Many
factors must be taken into consideration such as: degree of
nearsightedness, farsightedness, or astigmatism; your age, and your
overall health. As with any type of surgery, risks are involved. It is
important to discuss any concerns with your surgeon and weigh the risks
and potential benefits.
Each patient’s vision is different and
different treatment options are available in order to give the best
possible results. So, if you would like to reduce or eliminate your need
for glasses or contacts, take advantage of a free consultation and find
out if LASIK is right for you.
The *IntraLase FS* and *iFS* Laser
Systems are ophthalmic surgical lasers indicated for use in patients
undergoing surgery or treatment requiring the initial lamellar resection
of the cornea. Contraindications may include corneal edema, glaucoma,
and keratoconus. Risks and complications may include corneal pain, flap
tearing, and epithelial ingrowth. Patients are requested to consult with
their eye care professional for a complete listing of contraindications
and risks. Results may vary for each individual patient. U.S. Federal
Law restricts this device to sale, distribution and use by or on the
order of a physician or other licensed eye care professional.
