Adaptive optics, as used with telescopes, comprise a closed-loop control system where the distortions (caused by the atmosphere) are measured and the deformable mirror is adjusted to compensate many times (hundreds/thousands) per second, since the atmosphere is constantly in motion. If the distortions of the eye are of a more static nature (which I suspect they are) then the closed loop control system wouldn't really be needed but instead a lens could be fashioned which corrected for all the measured distortions. I think we are close to having machines which could produce a lens having any arbitrary figure - see: http://www.opticam.rochester.edu/content/contents. htm
