    摘要： A system includes a radiation source, one or more beam-directing elements, and a controller. The controller is configured to cause the radiation source to emit one or more aiming beams at the beam-directing elements such that the aiming beams are directed, by the beam-directing elements, toward an eye of a patient, to verify that each of the aiming beams is properly directed by the beam-directing elements, and, in response to verifying that each of the aiming beams is properly directed by the beam-directing elements, to treat the eye by causing the radiation source to irradiate one or more target regions of the eye with respective treatment beams. Other embodiments are also described.

    摘要： Microsurgical instruments having combined illumination, laser ablation, and viscoelastic injection functions. A surgical instrument includes a probe having a main lumen and a port at a distal end thereof. The probe may further include one or more optical fibers within the main lumen, the optical fibers configured to project laser light and illumination light. Laser light may be emitted from the distal end of the probe for disrupting an ocular tissue, while illumination light may be simultaneously emitted, axially or laterally, to provide enhanced visualization of the intraocular space during tissue disruptance. Upon disrupting the tissue, a viscoelastic fluid may be injected from the port to maintain an integrity of the intraocular space.

    摘要： 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.
