METHODS FOR CONTROLLING A LASER OF A PROCESSING APPARATUS AND PERFORMING A SURGICAL PROCEDURE FOR THE SEPARATION OF A VOLUME BODY, A PROCESSING APPARATUS, A COMPUTER PROGRAM AND A COMPUTER-READABLE MEDIUM
The invention relates to a method for controlling a laser (18) for the separation of a volume body (12) with an anterior interface (16) and with a posterior interface (14): determining a depth relief (48) of the volume body (12) to be generated between the anterior interface (16) and the posterior interface (14); determining a reference point (52) of an axis of symmetry of the determined depth relief (48) or of a respective interface (14, 16) by means of the control device (20); controlling the laser (18) starting from the determined reference point (52) in tracks circle-like at least in certain areas such that it emits pulsed laser pulses in a shot sequence in a predefined pattern into the material, wherein the interfaces are generated by means of an interaction of the individual laser pulses with the cornea (44) by the generation of a plurality of cavitation bubbles (40) along the circle-like tracks. Further, the invention relates to a processing apparatus, to a computer program as well as to a computer-readable medium.
SYSTEM AND METHOD FOR NOMOGRAM-BASED REFRACTIVE LASER SURGERY
The present disclosure provides a refractive laser surgery system including a processor having access to memory media storing instructions or sets of instructions executable by the processor to identify a surgical parameter; correct the surgical parameter based on a nomogram specific for the refractive laser surgery system to provide a nomogram-based corrected surgical parameter; store the surgical parameter and the nomogram-based corrected surgical parameter in the memory media as data for a patient or for one or both eyes of the patient; and compare the surgical parameter and nomogram-based corrected surgical parameter to generate a graphical representation of the surgical parameter, a target outcome parameter associated with the surgical parameter, or both, and the nomogram-based corrected surgical parameter, to generate a warning based on a comparison of the nomogram-based corrected surgical parameter to the surgical parameter or an absolute value, or both. Methods of using the system are also provided.
METHOD FOR ADAPTING TREATMENT COORDINATES FOR A TREATMENT WITH AN OPHTHALMOLOGICAL LASER
A method is disclosed for adapting treatment coordinates for a treatment of an eye with an ophthalmological laser of a treatment apparatus. The treatment apparatus includes a contact element for fixing the eye. The method includes acquiring at least a first image of the eye, before the eye is fixed by the contact element, and determining treatment coordinates of the eye by means of the first image, determining orientation points of the eye and the position thereof in the first image; acquiring a second image of the eye, after the eye has been fixed by the contact element, wherein the position of the respective orientation points is determined in the second image. The method also includes determining a transformation matrix based on the respectively determined positions of related orientation points in the first and the second image, and adapting (S18) the treatment coordinates by the determined transformation matrix.
Angle-opening glaucoma treatment methods and apparatus
An iridocorneal angle of the eye can be opened with a plurality of treatment locations at least about 2 mm radially outward from a limbus of the eye. The opening on the angle can be beneficial for treating both narrow angle glaucoma and open angle glaucoma. The plurality of treatment locations located away from the limbus can decrease invasiveness and complexity of the procedure. The plurality of treatment locations at least about 2 mm away from the limbus can provide tensioning to zonules coupled to the lens of the eye to flatten the lens of the eye, which can allow the iris to move posteriorly so as to open the iridocorneal angle. The plurality of treatment locations may comprise scleral locations, in which shrinkage of scleral tissue at the plurality of treatment locations provides tensioning to the zonules.
SPATIAL LIGHT MODULATION TARGETING OF THERAPEUTIC LASERS FOR TREATMENT OF OPHTHALMOLOGICAL CONDITIONS
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 the treatment of eye conditions
Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.
Patient interface for ophthalmologic diagnostic and interventional procedures
Configurations are described for conducting ophthalmic procedures to address cataract-related clinical challenges. In one embodiment, a one-piece patient contact interface may be utilized to couple a diagnostic and/or interventional system to a cornea of a patient; in another embodiment, a two-part configuration may be utilized; in another embodiment, a liquid interface two-part embodiment may be utilized.
Patient interface for ophthalmologic diagnostic and interventional procedures
One embodiment is directed to a patient interface system for ophthalmic intervention on an eye of a patient, comprising: a housing; an optical lens coupled to the housing and having a focal axis; a eye surface engagement assembly coupled to the housing and comprising an inner seal having an inner seal diameter and being configured to circumferentially engage the eye, an outer seal having an outer seal diameter and being configured to circumferentially engage the eye, and a tissue migration bolster structure configured to be positioned circumferentially between the inner and outer circumferential seals and to prevent migration of tissue of the eye toward the eye surface engagement assembly when a vacuum load is applied within the assembly to cause vacuum engagement of the inner and outer seals against the eye.
SYSTEMS AND METHODS FOR AFFECTING THE BIOMECHANICAL PROPERTIES OF CONNECTIVE TISSUE
A device for delivering ablative medical treatments to improve biomechanics comprising a laser for generating a beam of laser radiation used in ablative medical treatments to improve biomechanics, a housing, a controller within the housing, in communication with the laser and operable to control dosimetry of the beam of laser radiation in application to a target material, a lens operable to focus the beam of laser radiation onto a target material, and a power source operable to provide power to the laser and controller.
Delivery system and method of use for the eye
An apparatus having an inserter device with a shaft disposed in an interior space and an intraocular implant adapted to self-retain to an inner wall of Schlemm's canal. The intraocular implant has a proximal portion sized and shaped to reside within an anterior chamber of the eye, the proximal portion having a proximal opening; a distal portion sized and shaped to reside within Schlemm's canal of the eye, the distal portion having a distal opening, and a passageway extending in a straight line from the proximal opening to the distal opening to conduct fluid from the anterior chamber to Schlemm's canal. The shaft of the inserter device is adapted to advance the intraocular implant out of the interior space and through an inner wall of Schlemm's canal.
