Publication number: 20230141548Abstract: In some embodiments, an ophthalmic laser system may be provided that does not include a traditional laser console. Instead, the treatment device may be configured to house the treatment light source within the device handle. Additionally, in some embodiments, the handheld treatment device may include a user interface, such as dials and buttons, for adjusting various parameters of the therapeutic light. With certain embodiments, the self-contained handheld treatment device may be operated independent of an AC power source. For example, in some embodiments, the handheld treatment device may be battery powered. Additionally, the handheld treatment device may be disposable or may utilize replaceable distal tips in certain embodiments. Certain embodiments may be particularly designed for transscleral cyclophotocoagulation. Also, treatment guides are provided that may be configured to couple with a treatment device to align the device with a target tissue of the eye.Type: ApplicationFiled: January 12, 2023Publication date: May 11, 2023Applicant: IRIDEX CorporationInventors: Howard Chen, David Buzawa

Publication number: 20200323688Abstract: The present invention generally relates systems, methods, and devices for treating an eye of a patient. In some embodiments, a system may be provided that includes a console for generating a treatment laser and an illumination light. The system may further include a treatment probe for delivering the illumination light to an eye so as to illuminate the ciliary process of the eye. With the illuminated ciliary process, the treatment probe may be aligned to deliver the treatment laser from the console to the ciliary process of the eye for the purpose of treating a patient for glaucoma. In some embodiments, a treatment probe may be provided with an illumination fiber for delivering light to specific portions of the eye or at desired angles in order to illuminate the ciliary process. In some embodiments a treatment probe may be configured to cooperate with a removable light pen for eye illumination.Type: ApplicationFiled: June 29, 2020Publication date: October 15, 2020Applicant: IRIDEX CorporationInventors: Steven D.

Patent number: 10500094Abstract: 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.Type: GrantFiled: June 7, 2017Date of Patent: December 10, 2019Assignees: IRIDEX Corporation, National University Hospital (Singapore) PTE LTD, National University of SingaporeInventors: David Buzawa, Paul T.

Patent number: 10238540Abstract: Embodiments of the invention provide systems for treating the retina and/or other areas of a patient's eye. The procedures may involve using one or more treatment beams (e.g., lasers) to cause photocoagulation or laser coagulation to finely cauterize ocular blood vessels and/or prevent blood vessel growth to induce one or more therapeutic benefits. In other embodiments, a series of short duration light pulses (e.g., between 5-15 microseconds) may be delivered to the retinal tissue with a thermal relaxation time delay between the pulse to limit the temperature rise of the target retinal tissue and thereby limit a thermal effect to only the retinal pigment epithelial layer. Such procedures may be used to treat diabetic retinopathy, macular edema, and/or other conditions of the eye. The treatment beam may be delivered within a treatment boundary or pattern defined on the retina of the patient's eye.Type: GrantFiled: February 5, 2016Date of Patent: March 26, 2019Assignee: IRIDEX CorporationInventors: Kingman Yee, David Buzawa

Publication number: 20060187978Abstract: A laser system that includes a diode pump source. A frequency doubled solid state visible laser is pumped by the diode pump source and produces a pulsed laser output with a train of pulses. Resources provide instructions for the creation of the pulsed output, with on and off times that provide for substantial confinement of thermal effects at a target site. This laser system results in tissue specific photoactivation (or TSP) without photocoagulation damage to any of the adjacent tissues and without causing full thickness retinal damage and the associated vision loss.Type: ApplicationFiled: February 24, 2005Publication date: August 24, 2006Inventors: William Telfair, Ronald Avisa, Stuart Mohr, David Buzawa

Publication number: 20060041291Abstract: A treatment apparatus includes a cannula with a cannula lumen. The cannula has a first average diameter. A probe is positionable in the cannula lumen. The probe has a first section with a second average diameter and a second section with a third average diameter that is less than the second average diameter. At least a portion of the second section has a curved section with at least one radius of curvature. The radius of curvative is selected to provide that as the second section passes through the cannula lumen a first side of the second section is tangential to a first side of the cannula lumen, and a second opposing side of the second section is tangential to a second opposing side of the cannula lumen.Type: ApplicationFiled: August 16, 2005Publication date: February 23, 2006Inventor: David Buzawa
