Abstract

These are exciting times for people interested in noninvasive assessment of the eye for clinical applications. Aberrations of the eye are now routinely measured and are able to be corrected with adaptive optics. These possibilities bring up a number of issues that I'll discuss.

  1. Aberrations are most severe at night. We still need a good test for assessing night vision. What are the requirements for such a test?

  2. It is desirable to augment the Zernike expansion with shape descriptors specific to ocular anomalies. For refractive surgery the anomaly is a sharp steepening of the wavefront near the ablation perimeter. The new element to be discussed is how to make the shape descriptor terms orthogonal to the Zernike terms.

  3. This meeting has traditionally been a forum for discussions of standards for specifying wavefronts and for testing wavefront instruments. I'll continue that tradition.

  4. Fundus cameras with unprecedented resolution in x, y and z will soon be in the clinic. Their operation will be discussed.
