A gradual curving of the flexible housing tube may be configured to gradually curve the optic fiber. An actuation of the actuation mechanism control may be configured to gradually straighten the flexible housing tube. A gradual straightening of the flexible housing tube may be configured to gradually straighten the optic fiber.
Laser treatment apparatus
Operations of a laser treatment apparatus are facilitated. A laser treatment apparatus of an embodiment includes an illumination system, observation system, irradiation system, illumination-area changing part, irradiation-condition setting part and controller. The illumination system illuminates an eye fundus. The observation system is used for observing the fundus illuminated. The irradiation system irradiates aiming light of a preset pattern and treatment light consisting of laser light of a pattern determined based on the preset pattern onto the fundus. The illumination-area changing part is used for changing an illumination area of the fundus by the illumination system. The irradiation-condition setting part sets irradiation condition of the aiming light and/or treatment light from the irradiation system. The controller controls the illumination-area changing part based on the set irradiation condition to change the illumination area.
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.
Method and device for combined temperature-controlled laser therapy by means of a multifunctional therapy laser
A laser therapy device includes a solid-state laser configured for a CW operation and including a pump source, and a controller configured to generate at least one first pulse of the laser in a first-pulse operation. The controller is configured to switch on the pump source to a pump power level S1 at least once during the first-pulse operation. A rise time E, after which the pump power level S1 of the pump source is attainable and starting from the time the pump source is switched on, is in a range of 50 ns to 350 ns.
SYSTEM AND PROCESS FOR PREVENTION OF MYOPIA
A process for preventing or treating myopia includes applying a pulsed energy, such as a pulsed light beam, to tissue of an eye having myopia or a risk of having myopia. The source of pulsed energy has energy parameters including wavelength or frequency, duty cycle and pulse train duration, which are selected so as to raise an eye tissue temperature to achieve therapeutic or prophylactic effect, such as stimulating heat shock protein activation in the eye tissue. The average temperature rise of the eye tissue over several minutes is maintained at or below a predetermined level so as not to permanently damage the eye tissue.
Scanning laser ophthalmic treatment system and method of operation
An ophthalmic laser treatment delivers patterned laser energy to an eye of a patient. A pattern-scanning laser device of the laser treatment system includes a laser module, a scanning module and delivery optics. The laser module generates laser energy (e.g. via a green laser diode), which is directed to the scanning module via a fiber optic cable. The scanning module produces the patterned laser energy by reflecting the laser energy into the delivery optics at different angles via a dielectric MEMS scanning mirror. The delivery optics includes an F-theta lens, a motorized and wirelessly-controlled spot-size selector module, and a focusing lens. A mobile computing device receives parameter information via a graphical user interface or voice control and sends the parameter information to the pattern-scanning laser device. In response to receiving activation signals from an activation unit, the pattern-scanning laser device emits the patterned laser energy based on the parameter 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.
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, and inner bore of the handle, an actuation lever of the handle, a housing tube, and an optic fiber disposed within the inner bore of the handle and the housing tube. The housing tube may have a first housing tube portion having a first stiffness and a second housing tube portion having a second stiffness. The second stiffness may be greater than the first stiffness.
