Embodiment Construction

[0045] figure 1 A therapeutic apparatus for ophthalmic surgical treatment methods similar to those described in EP 1159986A1 and US 5549632 is shown. figure 1 The therapeutic device 1 is used for correcting visual defects of a patient's eye 2 according to the known femtosecond LASIK method. For this purpose, the treatment device 1 has a laser 3 which emits pulsed laser radiation. In this case, the pulse duration is, for example, in the femtosecond range, and the laser acts in the cornea in the initially described manner by means of nonlinear optical effects. The treatment beam 4 emitted by the laser 3 along the optical axis 1 is incident here on a beam splitter 5 which directs the treatment beam 4 to a scanning unit 6 . The scanning unit 6 has scanning mirrors 7 and 8 which are rotatable about mutually orthogonal axes, so that the scanning unit 6 deflects the treatment beam 4 two-dimensionally. The adjustable projection optics 9 focuses the treatment beam 4 onto or into the...

Abstract

The invention relates to a system composed of auxiliary parts and medical instruments, wherein the instruments have a transmission / read unit, and the auxiliary parts have a radio frequency identification chip with a storage identification code. The auxiliary parts and the medical instruments conduct radio communication to exchange data. The transmission / read unit reads the identification code when the auxiliary parts are in used, and influences the operation of the medical instruments depending on the identification code. The transmission / read unit modifies or erases the identification code, thereby the auxiliary parts are of limit use.

Description

[0001] This application is a divisional application of an invention patent application entitled "Contact Lenses for Ophthalmic Surgery" with an application date of August 25, 2006 and a national application number of 200680030782.7 (PCT application number PCT / EP2006 / 008360). technical field [0002] The invention relates to a system consisting of accessory parts and medical instruments. [0003] The invention relates to a contact lens for ophthalmic surgery, the glass comprising a lens front surface designed for placement on the eye and a device for fixing the contact lens by negative pressure on the eye. Background technique [0004] Such a contact lens is described in WO 2005 / 048895 A1, which also relates to the fastening of the contact lens on a laser treatment device. [0005] Contact lenses in ophthalmic surgery are examples of adapters that mechanically couple a laser treatment device to an object. Such coupling is required because the accuracy of the positioning of t...
