An apparatus for laser eye surgery comprises a laser module, which is equipped to emit pulsed, focused laser radiation of a variable pulse repetition rate, and a processor-based control unit, which is equipped to receive at least one user input pertaining to a selection of one of several predefined pulse repetition rates over a user input and to control the laser module in accordance with the selected pulse repetition rate. In certain specific embodiments, the user interface enables input of two user entries, each of which relates to a selection of one of several predefined pulse repetition rates. The control unit controls the laser module for a first phase of a laser treatment in accordance with one input, and for a second phase of the laser treatment, it controls the laser module in accordance with the other input.

Apparatus for eye laser surgery and method for performing a transepithelial photorefractive keratectomy

The invention relates to an apparatus for a laser-assisted eye-surgery treatment system, comprising a first image-acquisition unit that is designed to acquire a first image () of an eye to be treated. The apparatus further comprises a computer arrangement which is designed to detect at least one first feature (') of the eye by means of image processing of the first image, and to determine a position and an orientation of the first feature in a coordinate system (S&#x2032;) of the treatment system. The computer arrangement is also designed to determine a position and an orientation of an incision (&#x2032;) to be produced in the eye in the coordinate system (S&#x2032;) of the treatment system as a function of the determined position and orientation of the first feature (&#x2032;) in the coordinate system and as a function of a previously determined relative position and orientation of at least one second feature (&#x2032;) of the eye with respect to the first feature (&#x2032;).

Device and method for a laser-assisted eye-surgery treatment system

A device () for ophthalmic radiation is provided. The device comprises a radiation interface (), an optical branch coupler (), and a plurality of ophthalmic units (). The radiation interface is adapted to at least one of output and capture radiation on an optical path (). The optical path is directable towards a patient's eye. The optical branch coupler is adapted to couple output radiation from a plurality of optical branches () into the optical path and to couple captured radiation from the optical path into the optical branches. The captured radiation is spectrally split by the optical branch coupler into the optical branches. Each of the optical branches has a different spectral range. Each of the plurality of ophthalmic units is arranged to couple to one of the optical branches.

Integrated device for ophthalmology

A test device to calibrate the pulse energy of a laser device which provides pulsed laser radiation includes a measuring head with multiple measuring probes. The test device is used in such a way that by means of the laser radiation, multiple test ablations are made on a test surface, in an arrangement corresponding to the relative spatial arrangement of the measuring probes, and the depths of the test ablations are then measured, with simultaneous use of the multiple measuring probes of the measuring head.

Test device for calibrating a laser device

A method and system for performing biomechanical diagnosis of eye disease may include a Brillouin light source to generate a Brillouin sample beam, and a second harmonic generation (SHG) light source to generate an SHG sample beam. Both the Brillouin sample beam and the SHG sample beam may be coincidentally directed to a biological tissue sample in a confocal manner to a focus position. Brillouin scattering resulting from the Brillouin sample beam may be detected to determine an elastomechanical property and a viscoelastic property of the sample. SHG scattering resulting from the SHG sample beam may be detected to determine an indication of a morphological structure of the sample. The sample may be an in vivo human cornea.

Optical instrument for biomechanical diagnosis of eye disease

There is provided an apparatus for recording a depth profile of a biological tissue, in particular a frontal eye section of a human eye, according to the principle of optical coherence tomography, comprising a light source adapted to generate a bundle of light rays, an interferometer arrangement having a beam splitter device adapted to spatially separate the bundle of light rays into a reference beam and a measurement beam directed toward the tissue, a reference beam deflection device adapted to deflect the reference beam, a beam superpositioning device adapted to spatially superimpose the deflected reference beam onto the measurement beam deflected by the tissue into a superpositioned beam, and a detector arrangement for detecting information in the superpositioned beam associated with the difference of the optical path length of the reference beam and the measurement beam.
