Systems and methods are described for determining an intraocular pressure (IOP) of an eye using a contact lens with a magnet placed on the cornea of the eye. A magnetic field is exerted on the magnet of the contact lens, and the magnet is displaced by the magnetic field. The system of the present disclosure determines the deflection of the cornea based on the magnetic displacement of the magnet and determines the IOP of the eye.

A disposable biocompatible (and preferably hypoallergenic) flexible cover for use with a tip of a probe of a contact ophthalmological instrument. The outer surface of the tip (at the closed end) of the cover is configured to match the surface of the cornea, while its inner surface is preferably dimensioned to be substantially congruent with the surface of the tip of the probe with which the cover is used. A method for use of the same.

Pumps for noncontact tonometry are provided. In one embodiment, a pump for noncontact tonometry includes a compression pump, a compression chamber, a first pressure sensor in communication with the compression chamber, a surge chamber, and a valve separating the compression chamber and surge chamber. The compression pump compresses a first volume of gas into the compression chamber. When the first pressure sensor detects a threshold pressure in the compression chamber, the valve opens and releases the gas into a surge chamber, where it combines with a gas residing in the surge chamber to form a puff of gas that escapes from the surge chamber through a flow-limiting nozzle. The components of the pump, which relies on passive rather than active components to create the controlled puff, can be assembled to have a profile that is portable and fit for home use.

Intraocular pressure sensors, systems, and methods of use. Implantable intraocular pressure sensing devices that are hermetically sealed and adapted to wirelessly communicate with an external device. The implantable devices can include a hermetically sealed housing, the hermetically sealed housing including therein: an antenna in electrical communication with a rechargeable power source, the rechargeable power source in electrical communication with an ASIC, and the ASIC in electrical communication with a pressure sensor.

Ophthalmological device including an applanation tonometer tip having a bi-curved cornea-contacting surface and method of using such device for measurement of intraocular pressure. The cornea-contacting surface includes a first rotationally symmetric portion a curvature of which is substantially adapted to that of a typical cornea and a second rotationally symmetric portion that is peripheral to and adjoining the first portion. In operation, the applanation of the cornea in an area corresponding to the first portion of the cornea-contacting surface is substantially negligible.

Glaucoma drainage implant system with intracular pressure sensor and microvalve, and external reading unit, including: (1) an ocular implant device including a main body attached to a cannula communicating through a microchannel passing therethrough with a sensor microchamber; the microchamber is in fluid communication with a microvalve regulating outlet passage of ocular liquid, the microvalve being covered by a plate in the main body, the implant device has also a flat coil energizing the sensor, microvalve and regulation microchip; and (2) an external reading unit receiving signals from the PIO sensor and displaying IOP pressure; the UEL includes an antenna and a main unit; where the antenna feeds by bursts of RF radio frequency energy to the implant sensor and when the sensor is energized, it returns a signal with information from the IOP, this signal being received by the antenna and sent to the main unit for processing.

Assemblies and methods for modifying an intraocular pressure of a patient's one or both eyes are disclosed. The assemblies and methods can be used to treat, inhibit, or prevent ocular conditions such as glaucoma, high intraocular pressure, optic disc edema, idiopathic intracranial hypertension, zero-gravity induced papilledema, and other optic pressure related conditions. An assembly can include a goggle including at least one cavity, a pump in fluid communication with the at least one cavity, and a control mechanism. The control mechanism can be operatively coupled to the pump and can maintain a target pressure or target pressure range in the at least one cavity, which, when the assembly is worn by a patient, is the area between a patient's eye(s) and wall surfaces of the goggle. Controlling the pressure over the outer surfaces of the patient's eye(s) can drive a desired change in the intraocular pressure of the eye(s).
