Semi-automated ophthalmic photocoagulation method and apparatus
An ophthalmic treatment system and method for performing therapy on target tissue in a patient's eye. A delivery system delivers treatment light to the patient's eye and a camera captures a live image of the patient's eye. Control electronics control the delivery system, register a pre-treatment image of the patient's eye to the camera's live image (where the pre-treatment image includes a treatment template that identifies target tissue within the patient's eye), and verify whether or not the delivery system is aligned to the target tissue defined by the treatment template. The control electronics control the delivery system to project the treatment light onto the patient's eye in response to both an activation of a trigger device and the verification that the delivery system is aligned to the target tissue, as well as adjust delivery system alignment to track eye movement.
INTRAOCULAR CYCLOPHOTOCOAGULATION DEVICE AND METHODS OF USE
An intraocular cyclophotocoagulation device having a proximal, reusable portion and a distal, disposable portion. The reusable portion includes laser treatment assembly comprising a laser diode and a collimating lens positioned a distance distal to the laser diode and configured to collimate light from the laser diode into a collimated laser beam and direct the collimated laser beam towards a distal end region of the proximal housing portion; and an imaging assembly. The disposable portion includes a laser guide extending through an elongate shaft and an aspheric lens positioned within the distal housing portion to receive the collimated laser beam from the proximal reusable portion and direct the collimated laser beam toward a proximal end of a fiberoptic of the laser guide and an illumination light guide and an illumination source positioned within the distal housing portion. Related devices, systems, and methods are provided.
METHOD FOR SUPPRESSING STRAY LIGHT, LASER-SURGICAL APPARATUS, OPTICAL OBSERVATION DEVICE, AND COMPUTER PROGRAM
A laser-surgical apparatus includes a laser emitting laser light with a narrowband wavelength distribution, a digital image sensor or a plurality of digital image sensors that separately record(s) different color channels that represent mutually different spectral wavelength distributions with in each case one maximum corresponding to a specific spectral color and produce(s) separate pieces of image information for the individual color channels, and a graphics module for combining the separate pieces of image information into one color image. In addition, it includes a manipulation module for suppressing the laser light in the color image, which makes it possible to electronically manipulate the pieces of image information of the color channel the spectral wavelength distribution of which has the largest overlap with the narrowband wavelength distribution of the laser light before the separate pieces of image information are combined or during the combining of the separate pieces of image information.
Steerable laser probe
A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an actuation lever of the handle, a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end, and an optic fiber disposed within an inner bore of the handle and the flexible housing tube. An actuation of the actuation lever may gradually curve the flexible housing tube and the optic fiber. An actuation of the actuation lever may gradually straighten the flexible housing tube and the optic fiber.
Selective photocoagulation
A method of scanning a laser beam across a set of cells includes during a first interval, scanning a laser beam across a set of cells; and during a second interval, deflecting the laser beam away from the set of cells. The first interval is selected to cause microcavitation in at least a portion of the cells from the set of cells.
SINGLE FIBER ILLUMINATED LASER PROBE WITH HIGH-ANGLE ILLUMINATION OUTPUT
The present disclosure relates to a fiber and a laser probe assembly with a probe tip that houses the fiber. In certain aspects, the fiber includes a core, an outer cladding surrounding the core, and an end face at a proximal and/or distal end of the fiber. The core is configured to transmit a laser light beam while the core and the outer cladding are both configured to transmit an illumination light. In certain aspects, a surface area of the end face corresponding to a cross-section of at least the outer cladding is treated with a roughening or polishing process to modulate an illumination light output angle of the fiber. Using a fiber that is configured to transmit a laser light beam as well as a wide-angle illumination light allows for a more compact fiber and probe tip, allowing for medical procedures that require a narrower probe.
Laser scanner apparatus and method
An apparatus for ophthalmic procedures contains a source of aiming and treatment laser beams, folded mirrors and lens arrays to cause the formation of a static pupil on a delivery mirror for observation and treatment by an operator of the apparatus.
OPHTHALMIC LASER TREATMENT DEVICE, OPHTHALMIC LASER TREATMENT SYSTEM, AND LASER IRRADIATION PROGRAM
An ophthalmic laser treatment device includes an irradiation unit that irradiates a patient's eye with laser treatment light and a control unit that controls the irradiation unit. The control unit acquires a motion contrast acquired by an OCT unit that detects an OCT signal of measurement light reflected from the patients eye and reference light corresponding to the measurement light, acquires irradiation target information based on the motion contrast, and controls the irradiation unit so as to irradiate the patient's eye with the laser light, based on the irradiation target information.
MULTI-CORE FIBER FOR A MULTI-SPOT LASER PROBE
The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.
OPHTHALMIC TREATMENT DEVICE AND CONTROL METHOD THEREFOR
The present invention relates to an ophthalmic treatment apparatus and a control method therefor, and provides an ophthalmic treatment apparatus and a control method therefor, the ophthalmic treatment apparatus comprising: a setting unit formed so as to set a treatment mode; a therapeutic light emission unit emitting therapeutic light at a target position of an eyeground multiple times so as to perform treatment; a monitoring unit for monitoring information on the state of the target position by the therapeutic light during the emission of the therapeutic light; and a control unit for determining whether a treatment intensity according to the treatment mode has been reached, by using the information monitored by the monitoring unit, and for controlling an operation of the therapeutic light emission unit on the basis of the determination.
