Abstract:
The program has demonstrated that the image degradation from a human cataract is caused primarily by random phase variations within and on the surface of the cataract. The cataract may be considered to be a quiescent, random phase distorting medium. The technique of phase aberration balancing was used to cancel the aberrations of an excised cataract. This procedure consists of forming a hologram of the excised cataract and subsequently using the hologram as a filter in conjunction with the cataract itself to correct what would otherwise be highly distorted imagery.
