Abstract:
An ophthalmic instrument comprising:(a) a retinal imager, said imager including optics for illuminating and imaging the retina of the eye;(b) means for generating a reference beam, said generating means being optically coupled to said imager optics to form a reference spot on said retina;(c) a wavefront sensor optically coupled to said imager optics for measuring the wavefront produced by optical aberrations within said eye and said imager optics;(d) first wavefront compensation means optically coupled to said imager optics for correcting large, low order aberrations in said wavefront;(e) a high resolution detector optically coupled to said imager optics and said first wavefront compensation means; and(f) computer means, said computer means connected to(i) said wavefront sensor,(ii) said first wavefront compensation means, and(iii) said high resolution camera,said computer means including second wavefront compensation means for correcting, small, high order aberrations.
