Executive Summary
Visx has received US FDA 510(k) clearance for a device that will allow doctors to instantly measure refractive aberrations during laser vision corrective surgery. The WaveScan wavefront system uses optics that project light into the eye and then analyse the returning wavefront using a Hartmann-Shack sensor, which contains thousands of tiny lenslets. The system will produce a WavePrint, similar to a "fingerprint" of the eye, which illustrates an accurate assessment of the patient's refractive errors, said the Santa Clara, California-based company.
