Abstract: Provided herein are a method and device for a wave front measurement in a human eye with respect to its objectively determined visual axis where the visual axis is determined prior to measuring the wave front. The visual axis is defined as a direction to the voveola of the bisectrix of two orthogonal laser beam doblets hitting the foveola in the points of equal depths of the foveola slopes. The wave front is measured by probing the eye with a laser beam oriented along the visual axis at a set of points in the pupil. Backscattered radiation is detected, the coordinates of the laser spots on the retina are measured, and the wave front is reconstructed from the refraction distribution over the pupil.
