Intraocular pressure in an eye is reduced by delivering a high resolution optical coherence tomography (OCT) beam and a high resolution laser beam through the cornea, and the anterior chamber into the irido-corneal angle along an angled beam path. The OCT beam provides OCT imaging for surgery planning and monitoring, while the laser beam is configured to modify tissue or affect ocular fluid by photo-disruptive interaction. In one implementation, a volume of ocular tissue within an outflow pathway in the irido-corneal angle is modified to create a channel opening in one or more layers of the trabecular meshwork. In another implementation, a volume of fluid in the Schlemm's canal is affected by the laser to bring about a pneumatic expansion of the canal. In either implementation, resistance to aqueous flow through the eye is reduced.

A collagen cross-linking system for treating a tissue of a patient, the system including: a catheter having a flexible shaft and a conforming member, the flexible shaft having distal and proximal ends, a shaft body extending between the distal end and the proximal end, the shaft body defining a lumen, the conforming member being fixed to the catheter shaft near the distal end, the conforming member comprising a membrane defining a cavity in fluid communication with the lumen; a fluid source coupled to the proximal end of the catheter, the flexible shaft of the catheter being configured so that a flow of photosensitizing fluid provided by the fluid source flows through the membrane of the conforming member; and a light source coupled to the proximal end of the catheter, the catheter being configured so that photo-activating light generated by the light source passes through the membrane of the conforming member.

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.

An ophthalmic laser system for generating a first beam at a first wavelength on a first beam path and a second beam at a second wavelength on a second beam path, and directing optics to selectively direct the first beam or the second beam to a treatment beam path. The ophthalmic laser system incorporates a reflex coaxial illuminator comprising a reflex mirror movable on an axis from a position out of the treatment beam path to a position in the treatment beam path to direct illumination into an illumination path coaxial with the treatment beam path. The reflex mirror is adapted to transmit a beam that follows the second beam path.

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.

The present invention relates to a drug delivery system comprising a core and a shell in which the core comprises a hydrolytically degradable polymer X which polymer backbone comprises pendant ester and acid functionalities and in which the shell comprises a hydrolytic degradable polymer Y. The hydrolytic degradable polymers X and Y are different polymers. Polymer X further comprises amino-acids in the polymer backbone and degrades via zero order degradation kinetics for a period of at least 3 months. Polymer Y degrades via auto-acceleration degradation kinetics.

An ophthalmic laser apparatus comprises a laser light source; a light guide device, configured to guide a laser beam generated from the laser light source; a support bracket, configured to support a patient's head for the patient's eye to be perpendicular to a horizontal plane; a positioning device to acquire data related to a position of the patient's eye; a laser beam projector, the laser beam projector being movable to be aligned with the patient's eye and projecting the laser beam from the light guide device; a moving stand, configured to move the positioning device and the laser beam projector along an X direction, a Y direction, and/or a Z direction; and a controller, configured to control the laser light source to irradiate the laser beam and to control the laser beam projector to project the laser beam toward the patient's eye.

A goniotomy surgical instrument (10) includes a hand grip portion (12) having an elongated configuration with proximal and distal ends. The instrument (10) includes a tip portion (14) extending from the distal end of the hand grip portion (12) and includes a shank (16) extending from the hand grip portion (12). The tip portion (14) includes a V-shaped distal end having first and second legs (18, 20). The first leg (18) extends at a first angle (α) from the shank (16) of the tip portion (14). The second leg (20) extends at a second angle (β) from the first leg (18). The shank (16) and the first and second legs (18, 20) are substantially coplanar.

A multiple-fiber scanning ophthalmic transscleral laser probe system capable of firing multiple laser spots sequentially on the perilimbal area through the use of multiple fibers and an optical switching mechanism is disclosed. The design aims to reduce probe motion on the surface of the eye during transscleral cyclophotocoagulation and pulsed transscleral laser therapy by allowing multiple laser shots to be fired sequentially in a partial circular pattern without any probe movement and without the use of moving parts inside the probe. Sequential firing from a fixed probe location allows precise power level for each treatment spot and prevents the probe tip getting caught on or damaging the conjunctiva.
