Abstract:
A system for precompensating the refractive properties of an eye, the eye having, in order, a cornea, a pupil, a lens and a retina, said system comprising:an optical means for generating a reflection from the retina of the eye;a lenslet array for separating the reflection from the retina into a plurality of individual beams with each said individual beam having a unique optical path length;a computer means for using said plurality of individual beams to create a digitized acuity map of the eye and to generate a signal, said digitized acuity map being indicative of the optical path lengths of said individual beams reflected from the retina, and said signal being indicative of a reverse of said acuity map; andan active mirror, said active mirror being programmed with said signal for precompensating light from a stimulus by reflecting the incoming light from said active mirror to make said optical path lengths of said individual beams appear to be substantially equal to each other.
