Abstract: A device for dispensing medicine to an eye from a container in a non-gravitational manner includes a housing defining a space for receiving the container of medicine. A pair of motors is provided on the housing on opposite sides of the receiving space. Each motor has an actuatable arm. A dispenser assembly is connected to the housing and includes a first end for securing to the container and a second end having a delivery port. The first and second ends are in fluid communication with each other and with the medicine in the container. The arms are actuatable into engagement with the container for urging the medicine out of the container, through the dispenser assembly, and out through the delivery port into the eye.

Abstract: Systems, devices, and methods for determining an intraocular pressure (IOP) of an eye are provided. A system may include a pump configured to generate a puff of air and a nozzle configured to direct the puff of air along a first axis toward the eye. The system may further include a light source distal of the nozzle and directed to emit a beam of light toward the first linear optical sensor along a second axis transverse to the first axis. A first portion of the beam of light illuminates a lateral surface of the eye and a second portion of the beam of light passes in front of the eye. The system may further include a first linear optical sensor disposed distal of the nozzle and configured to receive the second portion of the beam of light.

Abstract: An eye drop monitoring device for monitoring gravity-driven placement of an eye drop into an eye of a patient includes a light source configured to selectively direct light toward at least one of the eye and the eye drop. The light is backscattered by at least one of the eye and the eye drop. A light detector is configured to detect the backscattered light from at least one of the eye and the eye drop and responsively produce at least one backscatter signal. An accelerometer is configured to determine a spatial position of the device and responsively produce a device position signal. A processing unit is configured to receive the at least one backscatter signal and the device position signal and responsively produce a drop-on-target signal indicative of a likelihood that the eye drop fell into a predetermined position with respect to the eye.

Abstract: Systems and methods for biometric authentication in ophthalmic devices are provided. In one embodiment, a system includes: an ophthalmic diagnostic device configured to obtain diagnostic measurements of a patient's eye, the patient's eye including an iris and a cornea; an imaging device configured to capture an image of the iris; an optical sensor integrated with the imaging module and configured to detect a position of the iris with respect to the optical sensor; and a computing device in communication with the ophthalmic diagnostic device, imaging device, and the optical sensor. The computing device may be configured to: determine, based on the image of the iris and the position of the iris, whether the iris matches a known patient's iris; and perform a diagnostic measurement of the patient's eye based on the determining.

Abstract: An example device includes a lithium-based battery having conductive battery contacts protruding from a surface of the battery, where a non-conductive portion of the surface of the battery separates the conductive battery contacts. The battery is a type that undergoes an expansion during charging in which the expansion of the lithium-based battery includes an outward bulging of the non-conductive portion of the battery surface. The device includes a substrate having conductive substrate contacts. The conductive battery contacts are electrically connected to the respective conductive substrate contact via a flexible electrically-conductive adhesive that physically separates the conductive battery contacts from the respective conductive substrate contacts and allows for relative movement therebetween caused by the expansion of the lithium-based battery.
