Abstract
Kestrel Corporation has previously demonstrated that the Distorted Grating Wavefront Sensor (DGWFS) can successfully reconstruct wavefronts in severely scintillated conditions, and has an ongoing experiment investigating aberrations in the eye using a DGWFS. Existing aberrometers cannot accurately reconstruct wavefronts when large amounts of scattering or scintillation are present and so cannot be used with subjects who have conditions such as cataracts (opacification of the ocular lens). Consequently a large proportion of the population cannot utilize today's diagnostic aberrometers and so do not benefit from otherwise available treatments. As previously reported, a DGWFS has been integrated into an Shack-Hartmann based aberrometer provided by the International Laser Center, Moscow State University, however several issues became apparent regarding data collection from the human eye. Results from laboratory experiments intended to investigate and resolve these data collection issues will be discussed.
