Abstract: Certain embodiments provide a vacuum generation system with a cascade PID controller, a proportional valve, and a vacuum generator. The cascade PID controller allows the vacuum generation system to control the operating range of supply air pressure that is provided to the vacuum generator. By controlling the operating range of the supply air pressure, the vacuum generation system is able to avoid entering the decreasing or non-monotonic region of the vacuum generator.

Abstract: In certain embodiments, an optical system for obtaining surgical information includes a probe housing a first optical fiber, a light source, a photoanalyzer, and an optical circulator optically coupled to each of the first optical fiber, the light source, and the photoanalyzer. The optical circulator has a first port configured to receive source light generated from the light source, a second port configured to transmit the source light from the first port to the first optical fiber, and a third port configured to transmit return light in the first optical fiber from the second port to the photoanalyzer. The first optical fiber is configured to emit at least a portion of the source light in the first optical fiber from the probe to contact a body structure, and collect light returning from the body structure as a result of the portion of the source light contacting the body structure.

Abstract: A console light guide device for use with a control console includes an interconnected light tube array. The light tube array includes a translucent surface, a shaped body substantially surrounding an output connection port on an external face of a console panel, and linear branches arranged relative to the shaped body. Side-firing light-emitting diodes (LEDs) emit light into a corresponding end of the light tube array. An opaque light guard defines a shaped channel and branch channels. The light tube array nests within the opaque light guard such that light from the side-firing LEDs is emitted uniformly through the translucent surface without any internal scattering or bleeding of the light within the console. A control console such as an ophthalmic surgical console is also disclosed herein that includes the console light guide device.

Abstract: Disclosed is an ocular implant with a flexible leading tip and methods of deploying the ocular implant. The leading tip can comprise a tip distal segment and a tip proximal segment. The leading tip can be tapered such that a diameter or width of the leading tip along the tip proximal segment is greater than the diameter or width of the leading tip along the tip distal segment.

Abstract: Systems and methods for tracking the position and condition of an eye during an ophthalmic procedure include an ophthalmic device configured to measure characteristics of an eye, an eye tracker configured to capture a stream of eye images, and a logic device configured to analyze the stream of images to determine whether the eye is fixating on a target object, detect a predetermined blink sequence in the first stream of images, delay for a predetermined tear stabilization period, start a stable tear film interval, and during the stable tear film interval, capture at least one measurement of the eye using the ophthalmic device when the eye is fixating. The blink sequence may include a plurality of blinks in succession and the detection of the blink sequence may include processing the images through a neural network trained to detect an open eye and/or a closed eye.

Abstract: A method for quantitively evaluating contact lens edge lift and distortion. The method includes the steps of scanning an edge of a contact lens, modeling the edge profile, determining a best-fit line over the modeled edge profile, calculating the slope of the best-fit line at a contact lens edge point, and further calculating a slope edge angle (ESA) as a function of the slope, wherein the ESA is a highly effective metric for capturing the contact lens edge-lift relative to the intended shape of the lens. The method may be used to provide design feedback, predict clinical fitting outcomes, and for quality control purposes.
