What is LASIK?
LASIK is a laser procedure that reshapes the cornea to correct myopia, astigmatism, and hyperopia to reduce or eliminate the need for glasses or contact lenses. After the eye is “numbed,” an ultrathin flap is created with the Intralase FS150; a preprogrammed laser than ablates/reshapes the cornea beneath the flap (we use VISX Star 4 Custom Wavefront with iris registration); and the flap is put back into position. LASIK eye surgery takes about 20 minutes to do both eyes. Discomfort is minimal and visual recovery is quick: commonly 20/20 the next day.
iLASIK describes the use of our Intralase FS 150kHz femtosecond laser to make the LASIK flap and the VISX excimer laser to vaporize or ”ablate” the corneal tissue necessary for correction of myopia, astigmatism, and hyperopia. Our Intralase FS 150kHz femtosecond laser uses bladeless laser technology for performing the first step of LASIK and is the safest and most accurate method for corneal flap creation available today. This laser uses an infrared beam of light to precisely separate tissue through a process called photodisruption.
In this process, the focused laser pulses of the Intralase divide material at the molecular level with the transfer of heat or impact ot the surrounding tissue. After the corneal flap is made, it is lifted and the excimer laser (VISX Star 4 with Custom Wavefront) is used to ablate or vaporize the precise amount of cornea necessary to correct the patient’s refractive error. The flap is then put back into position, and corneal healing quickly occurs (patients typically go back to work the next day).
VISX Custom Wavefront
The VISX Custom Wavefront procedure tailors a distinct correction for each individual – in fact, each treatment is "designed” by the unique characteristics of the individual’s eyes. WaveScan technology captures unique imperfections in each individual’s vision and programs the excimer laser to correct for these during the LASIK procedure in order to minimize any imperfections or higher order aberrations at the conclusion of the procedure and thus, particularly improves low light and night vision.
