Laser In-Situ Keratomileusis (LASIK) can be used to treat low to severe levels of nearsightedness and moderate amounts of farsightedness and astigmatism.
LASIK combines the computer-controlled precision of the Excimer laser with the faster healing benefits of another type of refractive surgery called Lamellar Keratoplasty. While PRK treats the surface of the cornea, LASIK treats the inner tissue of the cornea. First, an instrument known as a microkeratome makes a flap in the outer layer of the cornea, at about 25 percent of its depth from the surface.
The flap, which remains attached on one side, is then folded back. Next, the Excimer laser sculpts the internal corneal tissue to the desired shape. The corneal flap is laid back in its original position, where it is allowed to dry for a few minutes. Due to the cornea's extraordinary natural bonding qualities, stitches are usually not required. LASIK results are usually realized sooner than with PRK.
There's a new standard for laser vision correction that's making things easy for physicians (just ask for AMO) and patients (just ask for the iLASIK™ procedure). The iLASIK solution is an advanced platform, yielding clinical benefits at every step ...
WaveScan™ TechnologyWaveScan technology captures unique imperfections in each individual's eye that could not have been measured before using standard methods for glasses and contact lenses
- This new level of measurement provides 25 times more precision than phoropter-driven prescriptions
- Provides the physician a new level of information to measure and correct unique imperfections in each individual's eye
IntraLase technology gives you the capability to precision-design your patient's intracorneal architecture in terms of diameter, depth, edge angle and morphology — creating the optimal stromal bed for the refractive procedure.
IntraLase technology delivers many of the essential components of the ideal LASIK flap, including:
- Stronger flaps through improved wound healing, preservation of Bowman's layer and flap edge healing results in corneal strength comparable to PRK1
- Enhanced safety through less ectasia, reduced epithelial ingrowth and folds, and less risk of infectious keratitis than PRK3
VISX™ TechnologyAdvanced CustomVue™ treatment can deliver Personal Best Vision™ that:
- Can potentially produce better vision than is possible with glasses and contact lenses4
- Is approved to treat the broadest range of individuals, even those with astigmatism
To treat nearsightedness, the cornea must be made flatter. This is accomplished by removing tissue from the center of the cornea.
To treat farsightedness, the central cornea must be made steeper. This is accomplished by directing the laser beam to remove tissue from around this area.
To treat astigmatism, the cornea must be made more spherical. By changing the pattern of the beam, more tissue is removed in one direction than the other.
