Ab externo intraocular shunt placement
11612517 · 2023-03-28 · ·

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.

MODULAR INTRAOCULAR LENS DESIGNS AND METHODS

A modular IOL system including intraocular primary and secondary components, which, when combined, form an intraocular optical correction device, wherein the secondary component is placed on the primary component within the perimeter of the capsulorhexis, thus avoiding the need to touch or otherwise manipulate the capsular bag. The secondary component may be manipulated, removed, and/or exchanged for a different secondary component for correction or modification of the optical result, on an intra-operative or post-operative basis, without the need to remove the primary component and without the need to manipulate the capsular bag. The primary component may have haptics extending therefrom for centration in the capsular bag, and the secondary component may exclude haptics, relying instead on attachment to the primary component for stability. Such attachment may include actuatable interlocking members.

OCULAR INJECTOR AND METHODS FOR ACCESSING SUPRACHOROIDAL SPACE OF THE EYE

An ocular medical injector is provided for drug delivery. A method includes inserting a puncture member of the medical injector into the eye until the puncture member reaches the SCS. The puncture member defines a lumen therethrough. With the puncture member disposed within the SCS, a flexible cannula is advanced distally through the lumen of the puncture member, beyond the distal end portion of the puncture member and along the SCS towards a posterior region of the eye. The flexible cannula has an atraumatic distal tip and defines a lumen therethrough. With the distal tip of the flexible cannula disposed within the SCS beyond a distal end portion of the puncture member, a therapeutic substance is administered to the SCS.

AUTOMATED IDENTIFICATION OF ASPIRATED SALINE SOLUTION DURING VITREORETINAL SURGERY

A method for identifying saline solution in an aspirated fluid mixture during vitrectomy or another vitreoretinal surgery includes estimating a fluid property value of the mixture via an electronic control unit (ECU). The mixture includes saline solution and either vitreous or silicone oil. The method includes identifying the saline solution as a primary constituent fluid of the fluid mixture, via the ECU, based on the fluid property value, and activating an indicator device in response to the primary constituent fluid being the saline solution. An automated system for identifying saline solution in the aspirated fluid mixture includes the indicator device and the ECU. A computer-readable medium includes instructions, executable by a processor to identify an aspirated fluid mixture during a vitreoretinal surgery, with execution of the instructions by the processor causing the processor to perform the method.
