An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

SURGICAL SYSTEM AND PROCEDURE FOR TREATMENT OF THE TRABECULAR MESHWORK AND SCHLEMM'S CANAL USING A FEMTOSECOND LASER

A target volume of ocular tissue is treated with a laser having a direction of propagation toward the target volume, where the target volume is characterized by a distal extent, a proximal extent, and a lateral extent. A layer of tissue at an initial depth corresponding to the distal extent of the target volume is initially photodisrupted using a femtosecond laser by scanning the laser in multiple directions defining an initial treatment plane. Tissue at one or more subsequent depths between the distal extent of the target volume and the proximal extent of the target volume is subsequently photodisrupted using a femtosecond laser by moving a focus of the laser in a direction opposite the direction of propagation of the laser and then scanning the laser in multiple directions defining an subsequent treatment plane. Photodisruption is repeated at different subsequent depths until tissue at the proximal extent of the target volume is photodisrupted.

Laser therapy for treatment and prevention of eye diseases

An ab externo automated laser treatment system for treating an eye in a subject, includes a non-contact laser source configured to generate a laser beam having at least one wavelength to treat the eye by directing the laser beam from a location spaced from the eye, wherein the at least one wavelength is a near-infrared wavelength in the range of about 0.5-2.2 μm, a laser scanner optically coupled to the non-contact laser source to receive the laser beam from the non-contact laser source and to scan the laser beam relative to the eye, and a processor, and memory including stored computer-readable instructions that, responsive to execution by the processor, cause the laser treatment system to direct the laser beam to a plurality of trans-scleral treatment locations to be irradiated in a predetermined treatment pattern on an external surface of the eye, wherein the trans-scleral treatment locations are 0-4 mm posterior to the corneolimbal junction, and wherein the laser beam is repetitively directed to the same irradiated trans-scleral treatment locations on the surface of the eye, and the trans-scleral treatment locations are irradiated at intervals sufficient to induce protective thermal preconditioning and therapeutic bio-stimulation of one or more of the trabecular meshwork and/or ciliary body without photocoagulation of the tissue of the eye. Trans-pupillary systems, patient interfaces, and methods are also disclosed.

A lens device for use in Selective Laser Trabeculoplasty (SLT) procedures is provided. The lens device includes four internal reflectors, each having a reflector surface configured to direct a laser beam pulse toward the trabecular meshwork region of a patient's eye. Each of the four internal reflectors is arranged to correspond to a particular quadrant of the patient's eye to enable the entire 360-degrees of the trabecular meshwork to be treated with laser pulses without rotation of the lens device. A method for performing an SLT procedure using the lens device is also provided. The method includes placing the lens device on the patient's eye, aligning the internal reflectors with the quadrants of the patient's eye, and directing laser pulses through each internal reflector until the trabecular meshwork in each quadrant of the patient's eye has been treated.

Voice control system for ophthalmic laser systems
20210366482 · 2021-11-25 ·

A voice control system for ophthalmologic laser treatment systems sets parameters for delivering laser energy based on voice commands and prevents potentially harmful parameters due to operator mistakes and misunderstood voice commands by providing incremental parameter adjustment and restricting the amount by which the parameters can be adjusted for each executed voice command. Valid voice commands include indications of which parameter to set, a value for the parameter, and whether to increase or decrease the value of the parameter. In one example, parameter values can only be increased or decreased by a certain percentage with respect to the current value. In another example, the parameters are adjusted by selecting the next highest or lowest value with respect to the current parameter value from a predetermined sequence of possible values for particular parameters. Voice control functionality can also be deactivated under certain conditions such as when it is determined that a parameter was not set.

20210353464 · 2021-11-18 ·

Transcorneal and fiberoptic laser delivery systems and methods for the treatment of eye diseases wherein energy is delivered by wavelengths transparent to the cornea to effect target tissues in the eye for the control of intraocular pressure in diseases such as glaucoma by delivery systems both external to and within ocular tissues. External delivery may be affected under gonioscopic control. Internal delivery may be controlled endoscopically or fiberoptically, both systems utilizing femtosecond laser energy to excise ocular tissue. The femtosecond light energy is delivered to the target tissues to be treated to effect precisely controlled photodisruption to enable portals for the outflow of aqueous fluid in the case of glaucoma in a manner which minimizes target tissue healing responses, inflammation and scarring.
