Benefits of technology

[0023] It is particularly preferred to recheck the eye correction state shortly before the oper

Problems solved by technology

Therefore, this can result in an incorrect association between the data set of the correction and the specific eye under operation.
This may be due to the system software used for maintaining

Embodiment Construction

[0029]FIG. 1 a schematic representation of an exemplary embodiment of the method according to the present invention in which, in a first step I, an eye 5 having a representative unique characteristic 10 is scanned using a reading or identification unit 40, determining the unique data 10 or the characteristic, here, for example, the pattern of the iris. Using a shot data acquisition unit 30, the existing defects of eye 5 or the intended basis for the shot data for correcting eye are determined as a data set. These two results are combined in a mixer stage M so that the unique data or the characteristic is added to the shot data set. Furthermore, it is possible to include the acquisition of patient data, which can also be added to the data set using a further input unit (not shown). This complete data set is then stored in storage device 45.

[0030] Later, in a second step II, the specific eye 5′ which is present for the operation and has the unique characteristic 10′ of the iris patte...

Abstract

A method for identifying the site of an operation during an operation, in particular using a laser system, with the help of unique data about the operation site. A first copy of the unique data is stored in a laser system, the unique data being located in the vicinity of the operation site and/or directly at said operation site. Before the start of the operation, the first copy and the unique data are compared to verify if they are identical and the result of said verification is forwarded to the laser system. In addition, a device for identifying an operation site during an operation includes a laser system having a storage unit for storing data and a reading unit configured to determine unique data about the operation site and to provide a first copy of the unique data to the storage unit. The device also includes a comparator device operably connected to the storage device and configured to compare the first copy and the unique data for identity.

Description

CROSS REFERENCE TO PRIOR APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 399,440, filed Apr. 17, 2003, which is a U.S. National Phase Application under 35 U.S.C. §371 of International Application No. PCT / EP01 / 12171, filed Oct. 22, 2001, which claims the benefit of German Patent Application No. 100 52 201.7, filed Oct. 20, 2000, all of which are incorporated by reference herein in their entirety.BACKGROUND [0002] The present invention relates to a method and a device for identifying an operation site to be treated, in particular an eye, in laser operations. [0003] In laser operations, in particular of an eye, data allowing individual treatment of an eye is required for controlling the laser. This data is usually acquired or determined as patient data; methods such as eyesight testing, refractometer, measuring the topography, for example, of the cornea or of the lens, as well as the aberration of the eye being used for this purpose. This d...
