Systems, devices, and methods for treating a glaucomatous eye are provided. Embodiments may provide a treatment probe for treating an eye of a patient. The treatment probe may have an elongate body with a contact surface at a distal end of the elongate body. A treatment fiber or light source may be housed in the treatment probe and may be configured to direct treatment energy from the contact surface. The contact surface may be configured to couple to a surface of the eye to deliver the energy into the target area. In many embodiments the contact surface may have a convex configuration with a rounded outer shape and edge that facilitates the sweeping of the probe surface across the eye during treatment delivery. In some embodiments the probe may be swept in arc motions while delivering treatment energy to the eye.

System and method for treating an eye

An apparatus includes a laser source and a scanner. The laser source is configured to generate electromagnetic radiation. The scanner scans at least part of a limbal area of an eye with the electromagnetic radiation generated by the laser source, thereby directing the electromagnetic radiation through an entire thickness of the limbal area of the eye without any contact with the eye and irradiating one or more regions of a trabecular meshwork of the eye with the electromagnetic radiation.

System and method for locating a surface of ocular tissue for glaucoma surgery based on dual aiming beams

A target surface in an eye is located using a dual aiming beam apparatus that transmits a first aiming beam of light and a second aiming beam of light. An optics subsystem receives a laser beam from a laser source, the first aiming beam of light, and the second aiming beam of light, and directs the beams of light to be incident with the target surface and aligns the beams of light such that they intersect at a point corresponding to a focus of the laser beam. An imaging apparatus captures an image of the target surface including a first spot corresponding to the first aiming beam of light and a second spot corresponding to a second aiming beam of light. A separation between the spots indicates that the focus is away from the target surface, while overlapping spots indicate the focus is at or on the target surface.

STENT IMPLANT FOR TREATING GLAUCOMA BY MEANS OF INTRAOCULAR FLUID DRAINAGE FROM THE ANTERIOR CHAMBER
20230218441 · 2023-07-13 ·

The present invention relates to a stent implant for treating glaucoma by means of intraocular fluid drainage from the anterior chamber, preferably in the suprachoroidal space. The stent implant according to the invention is designed to bring about a change in shape after being inserted into the eye, during which change the width and/or thickness or the flow cross-section is increased by more than 20%, preferably more than 200%, and particularly preferably by more than 400%, at at least one point of the stent implant. In the case of intraocular fluid drainage from the anterior chamber into the suprachoroidal space, a cyclodialysis cleft which may open can therefore be at least largely or completely closed. The proposed stent implant is provided in particular for intraocular fluid drainage into the suprachoroidal space. With appropriate adjustments, the stent implant can also be applied in trabecular, uveoscleral, uveolymphatic and subconjunctival applications for intraocular fluid drainage from the anterior chamber. Said implant can even be used for direct intraocular fluid discharge from the anterior chamber onto the surface of the eye.

Contact probe for the delivery of laser energy

Systems, devices, and methods for treating a glaucomatous eye are provided. An amount of pulsed laser energy is delivered to the pars plana of the eye by a hand-holdable device which comprises a hand-holdable elongate member and a contact member disposed on an end of the elongate member. A contact surface of the contact member is placed in direct contact with the eye so that a reference edge of the contact member aligns with the limbus and a treatment axis defined by the elongate member is angularly offset from the optical axis of the eye. The amount of pulsed laser energy delivered is insufficient to effect therapeutic photocoagulation but is sufficient to increase uveoscleral outflow so as to maintain a reduction from pre-laser treatment intraocular pressure. Amounts of pulsed laser energy will be transmitted to a circumferential series of tissue regions of the eye.

Near infrared illumination for surgical procedure

Systems, devices, and methods for surgical illumination and imaging of ophthalmologic structures within a human eye are disclosed. In various embodiments, an emitter, imaging sensor, and a system control image processor are configured to irradiate ophthalmologic structures with near infrared light, detect near-infrared scatter from the irradiated ophthalmologic structures and visible light in real-time and generate or otherwise cause an image to be displayed on the user display that includes the detected near-infrared scatter from the irradiated ophthalmologic structures displayed in real-time. In one or more embodiments, the image is a virtual image of the irradiated ophthalmologic structures generated at least based on near-infrared light scattering coefficients of the irradiated ophthalmologic structures. In certain embodiments, the image displayed on the user display includes the detected near-infrared scatter from the irradiated ophthalmologic structures overlaid on a real-time view from a surgical microscope.

COMBINATION TREATMENT USING PHACO AND ELT

Methods and apparatuses for the treatment of glaucoma using visible and infrared ultrashort laser pulses
11510813 · 2022-11-29 ·

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 fiber optically, 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.

Methods and apparatus for treating glaucoma

An ocular implant for treating glaucoma is provided, which may include any number of features. More particularly, the present invention relates to implants that facilitate the transfer of fluid from within one area of the eye to another area of the eye. One feature of the implant is that it includes a proximal inlet portion and a distal inlet portion adapted to be inserted into the anterior chamber of the eye, and an intermediate portion adapted to be inserted into Schlemm's canal. Another feature of the implant is that it can be biased to assume a predetermined shape to aid in placement within the eye.
