The present disclosure provides a system for automated fine adjustment of an ophthalmic surgery support in which an eye tracking system detects a detectable position of an eye. The direction and distance the support must be adjusted for the eye to be centered may be determined based on the detectable position. A control signal is generated and transmitted to a control device that adjusts the position of the support to center the eye. The disclosure further provides a method for automated fine adjustment of a support, which includes detecting a detectable position of an eye, determining whether the eye is centered in relation to the center of the detection field of an eye tracking system based on the detectable position, determining a direction and a distance the detectable position must be adjusted to be centered, and generating and transmitting a control signal to adjust the position of the support.

A therapeutic laser for use in treating ophthalmological conditions can be modulated by a spatial light modulation device in order to focus the therapeutic laser on a plurality of target locations simultaneously.

Systems and methods for removing an epithelial layer disposed over a stromal layer in a cornea irradiate a region of the epithelial layer with a pulsed beam of ablative radiation. The ablative radiation is scanned to vary the location of the beam within the region in accordance with a pulse sequence. The pulse sequence is arranged to enhance optical feedback based on a tissue fluorescence of the epithelial layer. The penetration of the epithelial layer is detected in response to the optical feedback. The use of scanning with the pulse sequence arranged to enhance optical feedback allows large areas of the epithelium to be ablated such penetration of the epithelial layer can be detected.

The present invention relates to a laser surgery apparatus for contact laser surgery and to a method of using the laser surgery apparatus.

The contact laser surgery apparatus further comprises a pulsed laser source (2) adapted to provide pulse durations in the femtosecond, picosecond and/or nanosecond range, and light transmitting means (9) connecting said laser source (2) to said optical fiber (4) of said scalpel (3) for conveying laser radiation from said laser source (2) to said optical fiber (4) such that the conveyed laser light is emitted at said uncoated contact surface of the fiber tip.

An apparatus and a method for cutting or ablating corneal tissue of an eye provide for detection of electromagnetic radiation exiting the eye. A detector is provided and coupled to a computer controlling the cutting or ablating laser radiation so that a two- or three-dimensional image of radiation exiting the eye can be generated.

A system and method: obtain optical coherence tomography (OCT) data for tissue of an eye of a subject; process the OCT data to identify structures such as collector channels in the tissue of the eye; based on the structures identified by processing the OCT data, select one or more target locations in the tissue for laser treatment; and perform the laser treatment on the eye at the one or more selected target locations.

The invention relates to a method for providing control data for an ophthalmological laser (12) of a treatment apparatus (10) for treating a cornea (16) of an eye. Hereto, a control device (18) of the treatment apparatus (10) may ascertain (S10) eye parameters from predetermined examination data; determine (S12) a respective diameter for respective optical zones (OZ) depending on the ascertained eye parameters, wherein a diameter for treating the cornea (16) is selected from the ascertained diameters of the optical zones (OZ); and provide (S14) control data, which includes the selected diameter of the optical zone (OZ).

Method for providing control data for an ophthalmological laser (12) of a treatment apparatus (10) for hyperopia correction of a cornea (16). As steps, the method includes ascertaining (S10) corneal data of the cornea (16) from predetermined examination data; determining (S12) correction parameters of the hyperopia correction and corneal parameters of a virtual cornea, which is assumed for the cornea (16) after treatment with the hyperopia correction, depending on the ascertained corneal data; determining (S14), if a preset limiting criterion is present for at least one correction parameter of the hyperopia correction and/or at least one corneal parameter of the virtual cornea, wherein exceeding at least one parameter limit in the hyperopia correction is examined by the limiting criterion; limiting (S16) at least one preset correction parameter of the hyperopia correction by a limit value if the limiting criterion is present; and providing (S18) the control data, which includes the hyperopia correction with the limited correction parameter.

A steerable laser probe may include a handle, an actuation structure of the handle, a housing tube, a flexible tube, an optic fiber, and a wire having a pre-formed curve. The flexible tube may be disposed within the housing tube wherein a distal end of the flexible tube projects out from a distal end of the housing tube. The optic fiber may be disposed within an inner bore of the handle, the housing tube, and the flexible tube. The wire may be disposed within the housing tube.

An imaging system includes an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The eye interface device interfaces with an eye. The scanning assembly supports the eye interface device and scans a focal point of an electromagnetic radiation beam within the eye. The beam source generates the electromagnetic radiation beam. The free-floating mechanism supports the scanning assembly and accommodates movement of the eye and provides a variable optical path for the electronic radiation beam and a portion of the electronic radiation beam reflected from the focal point location. The variable optical path is disposed between the beam source and the scanner and has an optical path length that varies to accommodate movement of the eye. The detection assembly generates a signal indicative of intensity of a portion of the electromagnetic radiation beam reflected from the focal point location.
