Methods of administering a liquid formulation of an ophthalmic agent to a topical ocular location of an eye are provided. Aspects of the methods include delivering to the topical ocular location a dose of the liquid formulation that can be wholly accommodated by the tear film of the eye. Devices and kits for practicing the methods are also provided. The methods, compositions and kits find use in a variety of applications, including therapeutic, diagnostic and cosmetic applications. Further aspects include wireless communication between a handheld dispenser of the ophthalmic agent and external devices(s) to provide various functions.

Topical ocular delivery of fluids with controlled mass dosing and wireless communication

Aspects of the invention include a device for fluid delivery to the ocular surface having a self-alignment system. The fluid delivery device includes a fluid package having a reservoir and one or more apertures, an actuator component configured to eject fluid from the reservoir through the one or more apertures and an image-based self-alignment system configured to align fluid ejected through the one or more apertures with a target location on the eye of a user. Also provided are methods of using the devices in fluid delivery applications, as well as a kit that includes components of the devices.

A system for ophthalmic surgery on an eye includes: a pulsed laser which produces a treatment beam; an OCT imaging assembly capable of creating a continuous depth profile of the eye; an optical scanning system configured to position a focal zone of the treatment beam to a targeted location in three dimensions in one or more floaters in the posterior pole. The system also includes one or more controllers programmed to automatically scan tissues of the patient's eye with the imaging assembly; identify one or more boundaries of the one or more floaters based at least in part on the image data; iii. identify one or more treatment regions based upon the boundaries; and operate the optical scanning system with the pulsed laser to produce a treatment beam directed in a pattern based on the one or more treatment regions.

Apparatus for patterned plasma-mediated laser ophthalmic surgery

A device for delivery of a precise amount of pharmaceutical fluid to the eye is provided. The device includes an ampoule for storing a liquid and an aperture through which the liquid is discharged. The device further includes a vibrating membrane that includes a needle which protrudes from the membrane and extends to the aperture to form a needle valve. The needle valve provides hermetic closure of the aperture to enable preservative-free storage of the pharmaceutical fluid in the device. The system further includes an electromagnetic transducer to shift the membrane back and forth in order to discharge liquid through the nozzle. Finally, the system further includes a vent to permit air to enter the ampoule as fluid is ejected from the ampoule. Preferably this vent includes a filter to prevent ingress of microbes or other contaminants to the ampoule.

Vented multi-dose ocular fluid delivery system

Fluid delivery devices and methods are described, where the device may comprise a piezoelectric actuator operatively coupled to an ampoule with fluid, under a preloading force. The ampoule may comprise a thin-walled thermoplastic package which includes one or more apertures positioned on the wall of the ampoule. The piezoelectric actuator may be configured to clamp at least partially around the circumference of the ampoule and apply oscillations to its wall. The oscillations, typically in ultrasonic frequency, produce cycles of acoustic pressure in the fluid, leading to ejection of the fluid droplets or streams from the apertures.

Piezoelectric dispenser with replaceable ampoule

A stimulation system stimulates anatomical targets in a patient for treatment of dry eye. The system may include a controller and a microstimulator. The controller may be implemented externally to or internally within the microstimulator. The components of the controller and microstimulator may be implemented in a single unit or in separate devices. When implemented separately, the controller and microstimulator may communicate wirelessly or via a wired connection. The microstimulator may generate pulses from a controller signal and apply the signal via one or more electrodes to an anatomical target. The microstimulator may not have any intelligence or logic to shape or modify a signal. The microstimulator may be a passive device configured to generate a pulse based on a signal received from the controller. The microstimulator may shape or modify a signal. Waveforms having different frequency, amplitude and period characteristics may stimulate different anatomical targets in a patient.

Systems and methods for treatment of dry eye

A visual function evaluation is performed using a sequence of interactions with a mobile device. A patient user may perform a variety of visual tests using the mobile device. The mobile device transmits the test results to a remote server implementing analysis of the visual function results using network service. The network service receives the test results, processes the results, and provides the processed results to a healthcare provider. The processed results may include trends of the user's visual function test performance. The healthcare provider, such as a physician, may optimize and administer treatment based on the data. Early detection of changes in visual function can enable the healthcare provider to individualize treatment, helping to prevent vision loss while minimizing visits to the office, discomfort, and expense.

Piezoelectric fluid dispenser

System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

Described here are stimulation systems and methods for stimulating one or more anatomical targets in a patient for treatment conditions such as dry eye. The stimulation system may include a controller and a microstimulator. The components of the controller and microstimulator may be implemented in a single unit or in separate devices. When implemented separately, the controller and microstimulator may communicate wirelessly or via a wired connection. The microstimulator may generate pulses from a signal received from the controller and apply the signal via one or more electrodes to an anatomical target. In some variations, the microstimulator may include a passive generation circuit configured to generate a pulse based on a signal received from the controller.
