The CustomVue procedure tailors a unique correction for each individual. It employs the VISX Wavescan and Waveprint system, a new diagnostic system that captures a “fingerprint” of the eye which is 25 times more precise than what was previously measurable by standard methods. Wavescan evaluates more than nearsightedness, farsightedness, and astigmatism; it captures other, more specific imperfections in each individual’s vision. The data is then used to generate an individualized treatment for a CustomVue procedure.
