Wavefront LASIK - The Revolution of Laser Vision Correction
Wavefront LASIK describes the most modern way to perform LASIK and is integral in iLASIK or bladeless custom LASIK. In LASIK, a superficial flap is made in the cornea. Intralase, a blade-free laser currently makes the most advanced and safest flap available. Intralase employs use of a laser to gently and precisely create a thin flap. The flap is then lifted and the area under the flap is reshaped in order to correct vision. After the flap is created, the most important goal is to correct the vision as perfectly as possible.
In the past, the laser vision correction part of the LASIK procedure was less refined. Surgeons were able to correct the prescription in your glasses and that is it. Non-custom LASIK was effective, but there were issues with visual side effects in a small percentage of patients. Dr. Jeffrey Martin offers Wavescan by VISX, a custom LASIK system that uses small lenses that give information from the front of the eye to the back of the eye. Each small lens collects information from the cornea back to the retina. Therefore, the vision correction is based on the entire visual system, not just the lower aberration orders of visual blur, nearsightedness, farsightedness, and astigmatism. By using wavefront LASIK, each laser vision correction ablation corrects more information including trefoil, comma, and spherical aberration. These are more fine tuned levels of visual blur that are not corrected with glasses or contact lenses. When Intralase and wavefront LASIK are combined, it is known as iLASIK.
