An ocular lighting assembly (10) including an anchor (16) and a plurality of light guides (14). The anchor is configured to mount to a surface of an eye (30) and to maintain the position of the plurality of discrete light guides. The plurality of light guides are arranged to guide light from a light source into the interior of the eye.

One embodiment is directed to a method for interfacing an ophthalmic intervention system with an eye of a patient, comprising: placing a patient interface assembly comprising a housing, an optical lens coupled to the housing, and an eye engagement assembly coupled to the housing, the eye engagement assembly comprising an inner seal and an outer seal, into contact with the eye of the patient by sealably engaging the eye with the inner and outer seals in a vacuum zone defined between the inner and outer seals; applying a vacuum load between the inner and outer seals to engage the eye using the vacuum load; and physically limiting an amount of distension of the eye in the vacuum zone.

A device for a hypodermic needle comprises a connector for connecting to a hypodermic needle, a sheath (22) which in use surrounds the hypodermic needle and a biasing device (24) between the connector and the sheath. The sheath is moveable between a first position into which it is biased by the biasing device and a second retracted position against the force of the biasing device, so that in use, the tip of the hypodermic needle is covered in the first position but a defined length of the hypodermic needle is exposed in the second position. The device also sets the position of the angle of the hypodermic needle and locks the sheath over the needle after use.

An intraocular shunt can be placed into the eye in an ab externo approach. A clinician may determine an entry area below a corneal limbus of an eye and a target outflow region. Thereafter, the clinician can insert a hollow shaft into the eye at the entry area toward an anterior chamber of the eye, the shaft carrying an intraocular shunt therein. The clinician can position an inflow end of the shunt within the anterior chamber of the eye and, while maintaining the shunt inflow end in the anterior chamber, can remove the shaft from the eye to release the shunt. Finally, the clinician can repositioning an outflow end of the shunt within the target outflow region and verify placement of the outflow end of the shunt within the target outflow region.

A shunt 10 for implantation in the human body for treating ocular disorders related to disorders of intraocular or intracranial pressure by providing for flow of aqueous fluid in the anterior chamber A of the eye and cerebrospinal fluid in the subarachnoid space B surrounding the optic nerve C. The shunt has a proximal end 12 which is implanted in the ocular anterior chamber and a distal end 14 which is implanted in the subarachnoid space. The shunt has a two-part construction, including a flexible distal tube 18 and a rigid proximal tube 20. The distal tube has a distal stop formation 26 near the distal end 14 which is located in the subarachnoid space upon implantation of the distal end, resisting withdrawal of the shunt. The proximal tube has a curved portion which conforms to the anatomical curvature of the ocular globe.

An ophthalmic speculum includes arms, a locking mechanism, and an air-flow system. The arms include a first arm and a second arm. Each arm has a retractor shaped to conform to an eyelid of a pair of eyelids of an eye. The retractors are substantially symmetrical about a lateral axis. The locking mechanism is coupled to the arms. The locking mechanism moves the arms to allow the retractors to retract the pair of eyelids, and fixes the arms into place to maintain retraction of the pair of eyelids. The air-flow system is coupled to at least one arm, and moves air in a region disposed outwardly from a surface of the eye.

Placing an intraocular shunt ab externo into an eye can include inserting the shunt into the eye and either before and/or after insertion, ballooning a target outflow region of the eye to permit an outflow end of the shunt to be enveloped within the ballooned target outflow region. An injector docking device can optionally be used to guide insertion of the needle and shunt into the eye.

A surgical fixation tool (10) includes at least one fixation member (12) which protrudes from a leg (16) of a proximal grasping portion (20). The at least one fixation member (12) includes a needle (28) with a sharp distal tip (29). The needle (28) protrudes distally from a support structure (30) that includes one or more sloped support surfaces (34, 36) that are sloped with respect to a needle shaft (27).
