Abstract: An intraocular lens (IOL) includes a lens body having an anterior surface and a posterior surface disposed about an optical axis, and a progressive phase step structure formed on a refractive surface profile of at least one of the anterior surface or the posterior surface, the at least one of the anterior surface or the posterior surface having an outer zone, an inner zone, and a transition zone continuously connecting the outer zone and the inner zone. The refractive surface profile in the outer zone provides a base power, and the refractive surface profile in the inner zone provides an add power. The progressive phase step structure includes a first annular ridge structure within the inner zone, and a second annular ridge structure extending radially from the transition zone to the outer zone.

Abstract: Systems and methods are disclosed for measuring fluid pressure in an ophthalmic surgical system. An example system comprises a fluid flow path and a pressure sensor system for measuring pressure in the fluid flow path. The pressure sensor system comprises a conductive, movable diaphragm having a first side and a second side, the first side of the diaphragm facing the fluid flow path, and an eddy current position sensor positioned on the second side of the diaphragm without contacting the diaphragm. The eddy current position sensor comprises a position sensor coil activatable by high frequency alternating current and signal conditioning electronics capable of sensing inductance or impedance or resonant frequency variation in the position sensor coil as a gap between the diaphragm and the position sensor coil changes and of translating that variation into a displacement signal correlated to fluid pressure. A method of measuring fluid pressure may be performed using one or more of the systems described herein.

Abstract: The present disclosure generally relates to microsurgical instruments having variable stiffness such as microsurgical instruments having variable stiffness for ophthalmic surgical procedures. In one embodiment, a surgical instrument includes a probe and a stiffener assembly. The stiffener assembly further includes a stiffener formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. Actuation of the stiffener along the length of the probe adjusts the stiffness of the probe, thus providing a user better control of the surgical instrument.

Abstract: A system for guiding an ophthalmic procedure is disclosed. The system includes a housing assembly with a head unit configured to be at least partially directed towards a target site in an eye. An optical coherence tomography (OCT) module and stereoscopic visualization camera are at least partially located in the head unit and configured to obtain a first set and a second set of volumetric data, respectively. A controller is configured to register the first set and second set of volumetric data to create a third set of registered volumetric data. The third set and second set of registered volumetric data are rendered, via a volumetric render module, to a first and second region. The first region and the second region are overlaid to obtain a shared composite view of the target site. The controller is configured to extract structural features and/or enable visualization of the target site.

Abstract: Embodiments disclosed herein provide devices, systems, and methods for reducing intraocular pressure. For example, the disclosed devices, systems, and methods are useful for reducing intraocular pressure resulting from conditions, such as acute glaucoma, on a short-term basis until a definitive surgical procedure is performed. More particularly, valved trocar cannula systems for reducing intraocular pressure resulting from conditions, such as acute glaucoma, pending surgical intervention in an operating room are disclosed. In practice, a trocar assembly is used to place a valved cannula assembly in a patient's eye, such as in the anterior chamber or pars plana, to reduce high intraocular pressure. The valved cannula is then left in the patient's eye for a period of time to continuously allow aqueous humor or liquid vitreous humor to flow therethrough, until the patient may be surgically treated in an operating room.

Abstract: A tracking system for quantifying retinal traction on a retina of a patient eye includes an indicator device, a stereo camera, and an electronic control unit (ECU). The stereo camera collects and outputs stereo image data. The ECU, which is in communication with the indicator device, executes a method by receiving the stereo image data from the stereo camera during an ophthalmic procedure and thereafter assigning tracking points as coinciding pixels within stereo image pairs. The ECU also automatically performs a digital image correlation (DIC) process using the stereo image pairs to ascertain relative motion of the tracking points, and associates relative motion of the tracking points with the retinal traction using a traction map. A numeric traction quotient is generated that is indicative of magnitude of retinal traction. The ECU executes a control action using the indicator device based on the numeric traction quotient.
