Abstract: Near-infrared/Mid-infrared lasers are used to de-claudicate glaucomatous tissue, translocate extra-ocular muscles, thermally pulsate palpebrae, and penileate/vasodilate superficial/epi-scleral membranes for dmg delivery. Diffractive optic element-mediated laser patterns may irradiate eye tissues under pulsed or continuous wave regimes with programmable durations and sequences for efficient treatments while minimizing adverse effects.

Abstract: A laser delivery system is configured to delivery light energy to soften and realign the tissue of the eye in order to increase accommodation and treat glaucoma. The laser system can be configured to increase a circumlental space of the eye and increase movement of a posterior vitreous zonule in order to increase accommodation. The light energy may comprise wavelengths strongly absorbed by collagen of the sclera. In many embodiments a heat sink is provided to couple to the conjunctiva and the heat sink comprises a material transmissive to the light energy absorbed by collagen, for example Zinc Selenide. The heat sink can be chilled to inhibit damage to the conjunctiva of the eye. In many embodiments, one or more layers of the epithelium of the eye remain substantially intact above the zone where the eye has been treated when the heat sink has been removed.

Abstract: Apparatus, systems, and methods for treating an eye utilizing ab externo pressure wave generation. The shockwave generator comprises a housing comprising a fluid-filled chamber and an eye-contacting surface or chamber configured to contact a surface of the eye. First and second coaxially-aligned electrodes disposed within the housing are configured to generate an electric arc across a gap between the electrode tips when energized and thus produce a shockwave in a fluid of the fluid-filled chamber. The shockwave generator is coupled to the surface of the eye before focusing a shockwave to a pre-determined location on or below the surface of the eye. A plurality of shockwave generators may be disposed within a fluid-filled chamber of a contact lens, which may comprise a contact balloon.

Abstract: Methods and system provide a focused spot having a cross-sectional size within a range from about 50 um to about 200 um full width half maximum (FWHM); the corresponding cavitation can be similarly sized within similar ranges. The ultrasound beam can be focused and pulsed at each of a plurality of locations to provide a plurality of cavitation zones at each of the target regions. Each pulse may comprise a peak power within a range generating focal negative peak pressures within a range from about 10 MPa to about 80 MPa. While the treatment pulses can be arranged in many ways within a region, in many instances the pulses can be spaced apart within a region to provide intact tissue such as intact sclera between pulses.

Abstract: The methods and apparatus disclosed herein can be used to treat glaucoma of the eye. The methods and apparatus can be configured to apply energy to the sclera, cornea, and/or other regions of the eye in order to shrink collagenous tissue near Schlemm's canal. Juxtacanalicular treatment of the sclera and/or cornea adjacent Schlemm's canal can be used to dilate Schlemm's canal, collector channels, and/or the Trabecular Meshwork. The methods and apparatus can be configured to apply energy to the sclera to generate scleral vacuoles in the sclera to improve uveoscleral outflow.

Abstract: The disclosure generally relates to medical systems, devices and methods, and more particularly relates to dispersing heat during energy delivery to a tissue. The device may comprise two layers—a first layer which is optically transparent and a second later that may be both optically transparent and heat conductive. One or both of the layers may be configured to absorb energy (e.g., light energy), but together may transmit from about 50% to 99.9% of incident energy to the target tissue. One or both layers may comprise graphene or sapphire. One or both layers may comprise glass or plastic. The two layers may be any combination of glass, graphene, plastic, or sapphire. The two layers may be in physical contact with each other and either directly or indirectly bonded together.

Abstract: System and methods for a corrective eye procedure include at least one application device configured to be positioned at a selected area of an eye (e.g., equatorial sclera, posterior sclera, cornea, etc.). The at least one device includes at least one channel and at least one illumination guide. A cross-linking agent source is coupled to the at least one channel. An illumination source is coupled to the at least one illumination guide. The at least one device delivers the cross-linking agent to the selected area of the eye. The at least one device delivers photo-activating light from the illumination source to the selected area of the eye after the cross-linking agent has been delivered. The photo-activating light includes one or more doses necessary for activating the cross-linking agent and for activating TGF-? isoforms to improve health of extracellular matrices in the selected area of the eye.

Abstract: A glaucoma treatment system includes: a cannula body configured to be positioned in an area of Schlemm's canal; an illumination guide extending along the cannula body; at least one drug source coupled to the cannula body; a cross-linking agent source coupled to the cannula body; and an illumination source coupled to the illumination guide. The at least one drug source includes a drug that promotes outflow of aqueous humor through the trabecular meshwork and into Schlemm's canal. The cannula body delivers the drug from the at least one drug source to the area of Schlemm's canal, and in response to changes in the outflow of aqueous humor, delivers the cross-linking agent to the area of Schlemm's canal. The illumination guide delivers photo-activating light from the illumination source to the area of Schlemm's canal. The photo-activating light activates the cross-linking agent, thereby stabilizing changes in the area of Schlemm's canal.

Abstract: A method for controlling activation of a cross-linking agent applied to an eye includes applying the cross-linking agent to a selected region of a cornea of the eye and initiating cross-linking activity in the selected region by activating the cross-linking agent with pulsed light illumination. The pulsed light illumination has a selectable wavelength, irradiance, dose, and on/off duty cycle. The wavelength, the irradiance, the dose, and the on/off duty cycle are adjusted in response to a determination of photochemical kinetic pathways for cross-linking activity and to control photochemical efficiency, depth of cross-linking, and density of cross-linking.

Abstract: A method and material for augmenting the shape and thickness of the cornea in situ includes applying a clear liquid collagen mixed with a customized crosslinker onto the augmentation surface or in a cavity (with or without a mold) and exposing the mixture to UVA radiation in vivo. Application of UVA at varying dosages demonstrate progressive optically clear gelation and biomechanical adherence properties, and in vitro optical properties (RI), mechanical suture strength and rheometric parameters are comparable to native corneal stromal tissue. Photochemical corneal collagen augmentation according to the invention makes it suitable to reconstruct and strengthen diseased and damaged eyes, ulcerated corneas, as well as provide a substrate for refractive onlay/inlay procedures and lamellar transplantation.

Abstract: Excitation and radiation techniques and apparatus for performing customized elasto-modulation of ocular tissue in an annular region around the cornea, such as for the purpose of ciliary translocation (ACT) or promotion of aqueous outflow to relieve ocular pressure are provided utilizing a transconjunctival incisionless scleral treatment. Laser radiation is for example applied to scleral tissue to decrease zonular slack, or alter equatorial offsets between lens and ciliary muscles as a treatment for presbyopia by way of example.

Abstract: A system for supplying optical power uses an optical switch or shutter at the handpiece. The optical switch is positioned between an open light-transmitting position and a closed light-reflecting position. A detector at the base of the system can be used to detect the position of the optical shutter in some situations. This can be used to control the operation of a high-intensity light source. In this manner, the system can be controlled at the handpiece without using electrical power at the handpiece.
