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 500 can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe 500 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 500 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.

Methods for the treatment of glaucoma using visible and infrared ultrashort laser pulses
11857463 · 2024-01-02 ·

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.

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 m, 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.

PLANNING DEVICE AND METHOD FOR GENERATING CONTROL DATA FOR AN OPHTHALMOLOGICAL LASER THERAPY DEVICE FOR STRUCTURES BRIDGING THE CORNEA IN A PRESSURE-REDUCING MANNER

A planning device that generates control data for an ophthalmological laser therapy appliance with a laser device and a control unit, includes a first interface for supplying various data and a second interface for transferring the control data to the control unit of the ophthalmological laser therapy appliance, which is embodied to generate control data for a scanning pattern for the ophthalmological laser therapy appliance from the supplied data, by application of which scanning pattern a structure can be produced in the cornea, the limbus, and/or the sclera of a patient's eye. The planning device is embodied to generate from the supplied data, control data for the scanning pattern of this structure and/or a structure for receiving the shunt implant.

Apparatus for patterned plasma-mediated laser ophthalmic surgery

System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

A system for ophthalmic surgery includes a laser source configured to deliver an ultraviolet laser beam comprising laser pulses having a wavelength between 320 nm and 370 nm to photodecompose one or more intraocular targets within the eye with chromophore absorbance. The pulse energy, the pulse duration, and the focal spot are such that an irradiance at the focal spot is sufficient to photodecompose the one or more intraocular targets without exceeding a threshold of formation of a plasma and an associated cavitation event. An optical system operatively coupled to the laser source and configured to focus the ultraviolet laser beam to a focal spot and direct the focal spot in a pattern into the one or more intraocular targets. The optical system focuses the laser beam at a numerical aperture that provides for the focal spot to be scanned over a scan range of 6 mm to 10 mm.
