Traditional LASIK surgery can provide excellent results in correcting a wide range of common vision problems like nearsightedness, farsightedness and astigmatism. These vision problems are known as lower order aberrations.

CustomCornea® is a new kind of LASIK procedure which takes a similar approach and can help with many of the same visual problems. There are two reasons CustomCornea® is different. CustomCornea® is the first laser vision correction procedure to go beyond reshaping your cornea based on your prescription for eyeglasses or contacts. The procedure is completely customized to your eyes and your eyes alone. Secondly, CustomCornea® can help with other vision problems that could not be detected previously, known as higher order aberrations. Experts believe these aberrations can be responsible for vision problems like glare and halos in low-light conditions and at night.

Higher order aberrations cannot be treated by traditional laser vision correction procedures, or even by wearing glasses or contacts.
CustomCornea® was the first laser vision correction procedure approved by the FDA to address higher order aberrations.
How CustomCornea® Works
There are three steps to every CustomCornea® procedure; Capture, Match and Treat.
In this first step, the
LADARVision® System captures your eyes' unique combination of higher and lower aberrations. The device creates a wavefront map of each eye by shining an eye-safe beam of laser light into the eye and measuring the reflected light waves as they pass through your visual system and exit the eye.
In this second stage, a wavefront map for each eye is input to the laser system, and converted to a guide for the laser. When both patient and doctor are ready for surgery to begin, the map is computer-matched with the eye's exact position so the treatment is extremely precise. Since each eye has its own unique wavefront map, treatment with
CustomCornea® is truly customized.
In this third step, the cornea is precisely reshaped using the
LADARVision® System, guided by the data from the wavefront map. The treatment is designed to correct your unique profile of both lower and higher order aberrations at the same time.

If you're interested in a CustomCornea® procedure, it's important to select a surgeon with this up to date equipment. While many surgeons with many different systems claim to provide customized laser vision correction, only one system has 2 FDA claims and has proven to improve LASIK precision -- The LADARVision® System from Alcon Laboratories.
