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 opthalmological laser treatment device comprising:
a treatment 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; and an evaluating unit which is programmed to:
determine an area of an optical zone of the eye based on a recorded image and determine an area of the predetermined surgical structure; anddetermine a degree of an instantaneous overlap between the optical zone of the eye and the predetermined surgical structure based on the recorded image,wherein the evaluating unit is programmed to determine an area of a pupil based on the recorded image and the area of the predetermined surgical structure and an intersection between the two areas.
