By using th e 27f phase wrapping method t he range of t he wavefront deformation to be corrected can be greatly enha nced. In a simulat ion, t he foil mirror and t he multi-micromirror system were compared for a comp ensation of ast igmatism of 1 diopter (D) (Fig. 17). On t he left hand side of Fig. 17 t he simulate d vision chart blurred by an ast igmat ism of 1 D is shown. In t he midd le t he vision after correction with a 37-element membran e mirror is depicted. 3 D yields considerable blur of t he smaller Snellen let ters.

Though t he acuity test is effective for assessing norm al hum an eyes, it is often inadequate in t he clinical dia gnosis of eyes with abnormal vision . Fi rst , when an eye cannot see 20/20 with t he best correction lenses, th e acuity test cannot specify t he opt ical defects such as th e high order aberrations. Second , if an eye can see 20/20 or better, th e acuity test cannot account for visual symptoms such as ghost images and halos. Wavefront optomet ers can be a powerful to ols for vision diagnosis.
