OPHTHALMOLOGIC LASER SYSTEM AND OPERATING METHOD

摘要

1. The invention relates to an ophthalmologic laser system and to an operating method. 2.1. Following refractive laser correction to the eye, secondary treatment can be required. The invention enables laser-supported secondary treatment of the cornea with high accuracy. 2.2. In addition to a laser (4) for light, a scanner unit (7) and a focusing lens (8), an ophthalmologic laser system (1) comprises a beam splitter (5) that directs radiation that reaches the beam splitter (5) from the direction of the area of examination through a confocal aperture orifice (11) onto a detector (12), and comprises a control unit with which a cornea (2) arranged in the examination area can be irradiated by means of the laser (4) at a lighting laser power and detection light can be registered by means of the detector (12). The cornea (2) is scanned in three dimensions, in that the cornea is irradiated at multiple points and detection light is registered from there. Based on the detection light, a laser cut (C) in the cornea (2) is identified and the form and/or position of the laser cut (C) calculated. 2.3. The invention further relates to refractive laser surgery.
