## Abstract

A laser system for performing ophthalmologic procedures comprising a pulsed laser for emitting laser pulses, a focusing optics for generating at least one focal point in the anterior region of a patient's eye, a deflection device for varying the position of the focal point in the anterior region of the patient's eye, and a control unit for controlling the deflection device. The pulsed laser has a pulse duration in the range of nanoseconds, and the laser system is designed as a handheld device.

## Claims

### Claim 1

A laser system for performing an ophthalmologic procedure, the laser system comprising:
a pulsed laser for emitting laser pulses, the pulsed laser having a pulse duration in a range of nanoseconds,
a focusing optics for generating at least one focal point in an anterior region of a patient's eye,
a deflection device for varying a position of the focal point in the anterior region of the patient's eye, and
a control unit for controlling the deflection device,
wherein the laser system is configured in a housing of the laser system in order to form a handheld device, the housing comprising handles and support points, wherein the support points are configured to rest on a face and on nose of the patient during the ophthalmologic procedure.

### Claim 2 (depends on 1)

A laser system according to claim 1, wherein the laser system is designed for performing an anterior capsulotomy or a posterior capsulotomy on the freely movable eye.

### Claim 3 (depends on 2)

A laser system according to claim 2, wherein the pulsed laser comprises a device which is designed for varying a frequency of the laser pulses in order to perform operations on the posterior region of the eye.

### Claim 4 (depends on 1)

A laser system according to claim 1, wherein the laser system is designed for a fragmentation of a lens of the eye.

### Claim 5 (depends on 1)

A laser system according to claim 1, wherein that the laser system comprises a touchscreen.

### Claim 6 (depends on 1)

A laser system according to claim 1, wherein the laser system has at least one lighting means designed for illuminating the eye during the ophthalmologic procedure.

### Claim 7 (depends on 1)

A laser system according to claim 1, wherein the laser system has a cable for power supply, via which the laser system can be plugged into a power socket.
