Therapeutic eye treatment with gases
An apparatus to maintain an environment over an anterior surface of a patient eye can include an enclosure sized and shaped to be seated about the patient eye to form a cavity within the enclosure. The enclosure can be configured to contain a fluid other than ambient air in contact with the patient eye. The apparatus can include a fluid regulator in communication with the enclosure, where the fluid regulator can be configured to regulate the composition of the fluid contained within the enclosure.
SYSTEM AND METHOD FOR EYE REGION VISUALIZATION IN A LASER SURGICAL SYSTEM
A system for imaging a region of an eye includes a laser source that outputs a laser beam; a first optical subsystem that couples to the eye; a focusing objective coupled with the first optical subsystem and the laser source; a visualization system having a depth of field and a field of view; a movement subsystem that moves the focusing objective and the visualization system; and a control system that controls the movement subsystem and the visualization system to: place the depth of field and the field of view at respective positions relative to a target volume so the volume is within the depth of field and the field of view, obtain an image of the region of the eye, and maintain the position of the field of view of the visualization system relative to the target volume during movement of a laser focus through the target volume.
DEVICES, SYSTEMS AND METHODS FOR MINIMALLY INVASIVE GLAUCOMA SURGERY
Devices and methods useable for forming opening in trabecular meshwork of mammalian eyes.
Methods and systems for large spot retinal laser treatment
In some embodiments, a system for providing a therapeutic treatment to a patient's eye includes a treatment beam source configured to transmit a treatment beam along a treatment beam path. The system further includes a processor coupled to the treatment beam source, the processor being configured to direct the treatment beam onto retinal tissue of the patient's eye and deliver a series of short duration pulses from the treatment beam onto the retinal tissue at a first treatment spot to treat the retinal tissue. In some embodiments, a pre-treatment evaluation method using electroretinography (ERG) data may be used to predict effects of treatment beams at different power values and to determine optimal power values.
IMAGE GUIDANCE METHODS AND APPARATUS FOR GLAUCOMA SURGERY
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.

Automated Laser Iridotomy
A system (20) includes a laser (48), configured to irradiate a target site (41) in an iris (35) of an eye (25), and a controller (44). The controller is configured to identify, in one or more images of at least part of the iris, an indication of fluid flow through the target site, and in response to identifying the indication, inhibit the laser from further irradiating the target site. Other embodiments are also described.
Device for treating glaucoma
An implantable device for treatment of glaucoma of the eye. In one aspect, the device includes an elongate duct for diverting aqueous humor from the anterior chamber of the eye, the elongate duct having a central axis with a proximal end and distal end opposite one another. A least one element is spaced apart from the proximal end and the distal end of said elongate duct and extends radially outward beyond an outer surface of said elongate duct in at least two directions transverse to the central axis of said elongate duct, wherein the at least one element has a distal portion with a tapered profile facing the distal end of said elongate duct. The at least one element is configured to deform in a tissue passage leading into the anterior chamber of the eye as it is inserted into the tissue passage in response to forces applied by surrounding ocular tissue of the tissue passage. Other aspects are also described and claimed.
SURGICAL SYSTEM AND PROCEDURE FOR TREATMENT OF THE TRABECULAR MESHWORK AND SCHLEMM'S CANAL USING A FEMTOSECOND LASER
A target volume of ocular tissue is treated with a laser having a direction of propagation toward the target volume, where the target volume is characterized by a distal extent, a proximal extent, and a lateral extent. A layer of tissue at an initial depth corresponding to the distal extent of the target volume is initially photodisrupted using a femtosecond laser by scanning the laser in multiple directions defining an initial treatment plane. Tissue at one or more subsequent depths between the distal extent of the target volume and the proximal extent of the target volume is subsequently photodisrupted using a femtosecond laser by moving a focus of the laser in a direction opposite the direction of propagation of the laser and then scanning the laser in multiple directions defining an subsequent treatment plane. Photodisruption is repeated at different subsequent depths until tissue at the proximal extent of the target volume is photodisrupted.
Computer-based operating room support system
A computer-based surgery support system and method for obtaining information of surgical procedures from networked equipment in an operating room, storing the retrieved information in a database, receiving a request for the stored information from a user terminal, and providing the stored information in accordance with the received request. The networked equipment may be configured for use in cataract surgical procedures, such as a phacoemulsification system.
