First Claim
Patent Images
1. An intraocular pressure monitoring system, comprising:
- a contact lens device that is removably engageable with an eye, the contact lens device including a sensor device to detect when a deformable portion of the contact lens device is indented by a predetermined amount;
a headset device that applies a force to indent the deformable portion of the contact lens device, the headset device including at least one force sensor coupled to a headset frame; and
a control system to activate the headset device to apply the force on the contact lens device, the control system being in electrical communication with the force sensor to record data from the force sensor when the contact lens device is indented by the predetermined amount.

Abstract
Some embodiments of the system described herein provide non-invasive intraocular pressure monitoring throughout an extended period. Such monitoring systems can be used for the diagnosis and management of glaucoma patients and those at risk for glaucoma. In some embodiments, the monitoring system provides intraocular pressure monitoring in the patient'"'"'s normal environment without the need to house the patient in a sleep laboratory.
