Abstract
An opthalmological apparatus for the refractive correction of an eye comprises a light projector for projecting laser pulses on to a focal point in the interior of the eye in order to break down eye tissue. The apparatus further comprises a positioning module for positioning the focal point (F) at different starting points, and a scanning module for moving the focal point (F) starting from, in each case, one of the starting points in accordance with a scanning pattern for a treatment subarea (a), the scanning pattern and the starting points being defined such that in a number of treatment subareas (a) separated from one another by tissue bridges, the eye tissue is broken down. Through the formation of a multiplicity of separate, disconnected treatment subareas (a) with broken down eye tissue, it is possible not simply to flatten off the curvature of the cornea () in order to correct a myopia but to change the curvature of the cornea () at virtually any desired locations and, in particular, also to change it asymmetrically for a refractive correction.
