Subjective adaptive correction of the aberrations of the human eye

We designed and built an experimental setup for subjective (manually controlled) correction of up to 12 orthogonal terms (excluding tilts and defocus) of the aberration of the human eye. In our experiments, the subject was looking through an adaptive optical system at the USAF resolution chart. By using the arrow keys of the computer keyboard, the subject was able to control the amplitudes of up to 12 orthogonal aberration terms, introduced by a deformable mirror, optically conjugated to the pupil of the eye. Preliminary statistical analysis on a group of 12 participants with 6 correction attempts per participant, demonstrated satisfactory correlation of aberration coefficients obtained by the same person in different correction attempts. The majority of the participants were able to improve the visual acuity by subjective optimization of the figure of the deformable mirror
