Problems solved by technology

Also, a slight misalignment of the registration laser 35 is similarly inconsequential, since the misalignment will result in a fixed offset from the center point of the pulsed beam

Embodiment Construction

[0031] attached figure 2 A block diagram of a preferred embodiment of an eye surgery system 100 according to the present invention is shown. The system includes an excimer laser device 110 , a scanning device 120 , a personal computer 150 and an eye tracking device 200 in the form of independent modules. The scanning device 120 includes a scanning control module 122 connected to a first interface 124 for receiving information from the eye tracking device and a second interface 126 for sending data to the eye tracking device. In a preferred embodiment, this interface is implemented by SPDIEF (Siemens Philips Data Interface). Eye tracking device 200 includes first and second interfaces 224 and 226, which are also preferably implemented by SPDIEF. The first interface 224 of the eye tracking device is connected to the first interface 124 of the scanning device through a first data communication line 225 . The second interface 126 of the scanning device is connected to the secon...

Abstract

The invention relates to a system and a method for the treatment of a patient's eye. The system comprises a laser apparatus, a scanning apparatus and an eye tracking apparatus for determining the actual position of the patient's eye and for generating alignment data of the patient's eye relative to a reference position of the patient's eye to the laser, said eye tracking apparatus being provided with a desired treatment shot file. Said scanning apparatus is connected via a first bidirectional bus to the eye tracking apparatus, said laser apparatus is connected via a second bidirectional bus to the eye tracking apparatus. The eye tracking apparatus adjusts the position data for each shot based on said alignment data of the patient's eye and provides aiming control signals representative ofthe target position data to the scanning apparatus for said shot via said first bidirectional bus.; The eye tracking apparatus comprises a comparator for comparing the target position data with the actual position data provided by the scanning apparatus for the shot to be fired. Moreover, said eye tracking apparatus is sending a command signal to the laser apparatus via said second bidirectional bus for firing the shot when the target position data is equal to the actual position data of the scanning apparatus for the shot to be fired.

Description

technical field [0001] The present invention relates to a high speed operating system and method for treating the eye of a patient, and more particularly to a system and method using a refractive laser system. Background technique [0002] WO / 95 / 27453A relates to an excimer laser eye surgery system using an optical aiming system, which is schematically shown in FIG. 1 . The excimer laser eye surgery system 10 is used to non-invasively reshape the surface of the eye 44 by delivering irradiation from the excimer laser 20 to desired locations in the region of the eye determined to be treated. Using a typical excimer laser, the pulsed beam 22 is set with a typical repetition rate of 60-100 pulses per second, a typical pulse length of 10-30 ns and has a pulse energy of about 200 mJ / pulse. The aiming laser 32 provides an aiming beam spot that coincides with the central axis of the laser irradiation of the pulsed beam. A registration laser 35 provides a registration beam aligned ...
