Rotating pairs of Zernike phase plates for compensating for the higher-order aberrations of the human eye

We present a method of using pairs of rotating Zernike phase plates as a precompensation unit to correct the higher-order aberrations (typically coma and trefoil) in the human eye. The rotational properties of the Zernike polynomials allow compensation of variable higher-order aberrations of the human eye with a small number of specially designed Zernike phase plates.
