Abstract: In certain embodiments, a system for aligning an eye with a patient interface of a laser device includes a camera, a display screen, and a computer. The camera records images of the eye through the patient interface of the laser device. A liquid is disposed between and is in contact with the patient interface and the outer surface of the eye. The images include an outline of the liquid. The display screen displays the images of the eye. The computer aligns the eye with the patient interface by: identifying the outline of the liquid in an image received from the camera; determining a misalignment of the eye according to the outline; and instructing the display screen to display a description of the misalignment.

Abstract: The present disclosure generally relates to microsurgical instruments for ophthalmic surgical procedures, and more particularly, methods and microsurgical instruments for vitreoretinal procedures. In certain embodiments described herein, a vitreoretinal procedure is performed utilizing two surgical instruments: 1) a treatment instrument configured to a) treat a target ophthalmic tissue (e.g., sever and remove the vitreous body), and b) infuse fluid into the intraocular space to maintain intraocular pressure (TOP); and 2) an illumination probe for providing illumination within the intraocular space. The combined treatment and infusion functionalities of the treatment instrument eliminate the need for a separate infusion cannula, thus enabling the vitreoretinal procedure to be performed with only two instruments and reducing the number of incisions made in the eye. Additionally, utilization of two instruments facilitates easier manipulation of the eye by a surgeon, as one of the two instruments can be used to “steer” the eye during the procedure.

Abstract: The invention relates to a method for producing embedded hydrogel contact lenses each having an insert that comprises alignment features capable of capable of aligning the insert in depth and radial position in a female mold half during cast molding of an embedded hydrogel contact lens. The alignment features protrude from the front surface, are rotationally symmetric with respect to the central axis of the insert and independently have a shape having a curvature being greater than 2 folds of the curvature of the molding surface so as to minimize contacting area between the alignment features and the molding surface. The use of such an insert can simplify the process for producing embedded hydrogel contact lenses and enable the process to be implemented readily in an automatic production.

Abstract: Techniques are disclosed for systems and methods to provide improved ocular aberrometry recovery. An ocular aberrometry system includes a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system and a logic device configured to communicate with the wavefront sensor. The logic device is configured to receive ocular aberrometry output data including at least the wavefront sensor data provided by the wavefront sensor, identify imaging artifact induced singularities in the received ocular aberrometry output data, determine corrected aberrometry output data based, at least in part, on the identified singularities and the received ocular aberrometry output data, and generate user feedback corresponding to the received ocular aberrometry output data based, at least in part, on the corrected aberrometry output data.

Abstract: A system, method, and apparatus for performing intraocular lens implantation using real-time surgical reference indicium are disclosed. An example method includes recording a patient specific pre-operative still image of an eye prior to cyclorotation of the eye when a patient lies down for surgery and generating at least one real-time multidimensional visualization of at least a portion of the eye for display. The method further includes using the patient specific pre-operative still image to at least produce at least one virtual surgical reference indicium including an ocular natural vertical axis of the eye and align the at least one virtual surgical reference indicium to the eye in conjunction with the real-time multidimensional visualization of at least a portion of the eye. The patient specific pre-operative still image is captured under a dilation condition selected from the group consisting of natural dilation, chemical dilation, and no dilation.

Abstract: A method for enhancing digital images during a microsurgery, e.g., an eye surgery, includes collecting digital images of target anatomy using a digital camera as the target anatomy is illuminated by warm white light. The method includes identifying, via a processor in communication with the digital camera, a predetermined stage of the microsurgery. Within the images, the processor digitally isolates a first pixel region, e.g., a pupil pixel region, from a second pixel region, e.g., an iris pixel region, and adjusts a characteristic of constituent pixels thereof. The method, possibly recorded as instructions in a computer-readable medium, may be used to enhance a red reflex at predetermined stages of an eye surgery. A system includes a lighting source for emitting warm white light having a color temperature of less than about 4000° K, the camera, and the processor.

Abstract: Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber.

Abstract: An intraocular lens (IOL) configured to support a first optic for functioning as a single lens IOL and configured to support a second optic for functioning as a dual optic IOL. The base includes a first optic for providing a base power. A recess in an anterior rim of the base is configured for positioning a radial extension of a second optic. The geometry of the recess is configured to securely couple to the radial extension to prevent rotation of the second optic relative to the base and prevent tilting of the second optic relative to an optic axis.
