Patent Images

1. A wavefront sensor for determining the wave aberrations of the living eye, said wavefront sensor receiving a reflected point source image of the retina of said eye, comprising:

  • a plurality of lenslets which form a lenslet array for receiving said reflected point source image of said retina and for creating an aerial image of the retinal point source;

    said lenslet array being configured such that it is capable of providing resolution for at least fifth order aberrations;

    a camera located adjacent to said lenslet array for viewing said aerial image of the retinal point source formed on each of said plurality of lenslets of said lenslet array; and

    a digital data processor connected to receive video output signals from said camera and for converting said video output signals to digital signals representative of said retinal point source aerial images, said digital data processor further calculating the wave aberrations of said eye so as to include at least fifth order modes, using said representative digital signals.
