Ophthalmological Laser Treatment Device

摘要

An evaluating unit which is adapted to determine a degree of an instantaneous overlap between an optical zone of the eye and the structure, or at least a part of the structure effecting refractive correction, based on a recorded image. By determining the degree of overlap between the instantaneous optical zone and the structure to be introduced, it is possible to control the superposition of the optical zone with the tissue volume which is specifically altered by means of the laser cutting and, accordingly, to enable a maximum coverage.

主权项

1. An ophthalmological laser treatment device comprising:
a femtosecond laser configured to introduce energy into a portion of an eye of a patient according to a predetermined surgical structure; a light source configured to illuminate at least the portion of the eye; a detection device configured to record an image of at least the portion of the eye; an evaluating unit which is configured to determine a degree of an instantaneous overlap between an optical zone of the eye and the predetermined surgical structure or at least a part of the predetermined surgical structure effecting refractive correction based on a recorded image; and a contact element for mechanically fixating the eye.
