The Aberrometer System is a big help to surgeons in that it lets them see perfectly into these refractive fractions through rotating 3D images. But one may wonder about how the Aberrometer can do this. First, the Aberrometer releases a laser light with just a minimal energy right into the eye. Next, the eye then bounces back this light into the retina and then goes through the lens and cornea and exits as a wavefront. Then the Aberrometer gets hold of this wavefront and measures it to find out both lower and higher order aberrations of the entire optical system. Lastly, once the aberrations are determined, they are projected on-screen in exact 3D images.

From the measurements provided by the Aberrometer, the customized corneal ablation comes in next. The surgeons interface that data digitally with the Excimer Laser Eye Surgery System. It uses a high-speed computerized eye-tracking method that assists Laser Eye surgeons to boost the treatment process.

Since the eyes are making jumping movements constantly and very fast whether we like it or not, the eye-tracking system helps the surgeon scan the eye at a wicked speed of thousands of times per second. It therefore creates a very accurate display of the laser beam for the customized ablation surface. And by manipulating the system through the computer, micro-adjustments can be made to adjust the pinpoint laser beam in between pulses of light, making it possible to trace even the minutest movement your eye makes during the treatment process.

Besides the said facts, the Excimer Laser Eye Surgery also uses another type of laser, another minute beam of laser less than a millimeter wide, so minute that it’s even smaller that the width of a strand of human hair. By controlling it with the high-speed computer, the Excimer Laser Eye Surgery System moves this almost microscopic beam of light on the surface of the cornea in random, very fast and very tiny movements, and in an overlapping pattern. This way the surgeon gets to create an effective customized corneal shape which is unique to the patient’s prescription enabling his speedy visual recovery.
