The invention relates to a centering device (12) for determining a centering of a visual axis of an eye (14) to a beam path, wherein the centering device (12) comprises at least two color sources (16, 18), a control device (20) and a capturing device (22), wherein the color sources (16, 18) are arranged in the beam path of the centering device (12), wherein a respective color signal (17, 19) in a visible spectral range can be output by the color sources (16, 18) to an eye interface (26) via the beam path, wherein a wavelength of the respective color signals (17, 19) differs, and wherein the control device (20) is formed to control the capturing device (22) for ascertaining an eye orientation upon presence of a superposition criterion, by which a superposition of the color signals (17, 19) on the visual axis is indicated.
LASER SYSTEM AND METHOD FOR CORRECTION OF INDUCED ASTIGMATISM
There is provided a system, apparatus and methods for developing laser systems that can create precise predetermined clear corneal incisions that are capable of reducing induced astigmatism. The systems, apparatus and methods further provide laser systems that can provide these incisions at or below Bowman's membrane.
Integrated surgical system and method for treatment in the irido-corneal angle of the eye
Intraocular pressure in an eye is reduced by delivering each of a high resolution optical coherence tomography (OCT) beam and a high resolution laser beam through the cornea, and the anterior chamber into the irido-corneal angle along an angled beam path. The OCT beam provides OCT imaging for diagnostic purposes and surgery planning and monitoring, while the laser beam is configured to modify tissue. A volume of ocular tissue within an outflow pathway in the irido-corneal angle is modified to reduce a pathway resistance present in one or more of the trabecular meshwork, the Schlemm's canal, and the one or more collector channels by applying the laser beam to ocular tissue defining the volume to thereby cause photo-disruptive interaction with the ocular tissue to reduce the pathway resistance or create a new outflow pathway.
MODULAR LASER THERAPEUTIC DEVICE
The invention relates to a modular Modular Laser Therapy Device (MLTD) to be used by ophthalmologists for eye surgery that integrates three most frequently used therapeutic devices into a single, compact unit enabling the treatment with capsulotomy, vitreolysis and iridotomy, with selective laser trabeculoplasty and with photocoagulation. While providing such modular laser device a method is provided for optomechanically coupling different ophthalmic modules into the single unit using two laser sources.
METHOD FOR PROVIDING CONTROL DATA FOR AN OPHTHALMOLOGICAL LASER FOR PROVIDING A TRANSITION ZONE BETWEEN INTERFACES
The invention relates to a method for providing control data for an ophthalmological laser (12) of a treatment apparatus (10). As steps, the method includes determining an anterior (14) and a posterior (16) interface in a cornea (17) of a human or animal eye; determining a transition zone, in which the interfaces (14, 16) are connected to each other, wherein transition positions (24) are determined on the anterior interface (14), from which an incision progression of the anterior interface (14) is changed towards the posterior interface (16), and wherein transition positions (26) are determined on the posterior interface (16), at which an incision progression of the posterior interface (16) is changed towards the anterior interface (14), such that the respective incision progressions of the interfaces (14, 16) converge and connect to each other in the transition zone; and providing control data for controlling the ophthalmological laser (12), which includes the interfaces (14, 16) and the incision progression of the transition zone.
DUAL PORT LASER VITREOUS DISINTEGRATION DEVICE
A vitreous disintegration device with multiple intake ports and a laser for vitreous disintegrating. The probe includes a needle to accommodate the ports for a more continuous and fluidic uptake of vitreous from an eye of a patient. Additionally, the use of a laser may be employed to disintegrate the vitreous in a manner that avoids blocking of ports and thus, further promoting the fluidic uptake. The laser may reach the ports at the channel at substantially the same time or in succussion. Further, the use of a laser for the disintegrating means that cutter vibrations may be reduced.
Method for controlling an eye surgical laser and treatment device
The invention relates to a method for controlling an eye surgical laser for the separation of a volume body with a predefined posterior interface and a predefined anterior interface from a cornea, comprising controlling the laser by means of a control device such that it emits pulsed laser pulses in a shot sequence in a predefined pattern into the cornea, wherein the interfaces of the volume body to be separated are defined by the predefined pattern and the interfaces are generated by means of an interaction of the individual laser pulses with the cornea by the generation of a plurality of cavitation bubbles generated by photodisruption, wherein the predefined pattern is generated by means of a mesh-like guidance of the emitted laser pulses and the control device controls the shot sequence of the laser such that a common overlap area of the cavitation bubbles is generated between adjacent cavitation bubbles. Further, the invention relates to a treatment device, to a computer program as well as to a computer-readable medium.
