Method and system for the eyes of observation and – therapy, in particular apparatus for laser-assisted cataract surgery

摘要

Various aspects for a system for the eyes of observation or - therapy is described, which are individually or jointly a user in the case of a sequence of operations in ophthalmology, in particular a cataract operations and their preparation support. According to the first aspect, a two-part scanner comprising a rapid short-stroke and a slow long-stroke part via a 4 - f - optical system combined. According to the second aspect, the radiation between the scanners and a lens by means of an articulated arm is transmitted, with 4 - f - optical systems in the articulated arm, are used for. According to the third aspect, a main objective with certain focal width features, in order to obtain a large working distance, and thus the user to give freedom with respect to its working sequence. According to the fourth aspect, a particularly precise and quick referencing between a diagnostic biometry image and a current image during the instantaneous observation or of the following engagement. According to the fifth aspect, a preferred coupling an observation camera, the spatially in the region of the patient''s eye particularly little affected.
