Clinical Investigation of Eye C Better's Photobionic Intraocular Pressure Biomonitor Tonometer
A Prospective, Non-Randomized, Single-Center Clinical Investigation of the Safety and Performance of Eye C Better's Photobionic IOP Biomonitor Tonometer (PIB)
Source: ClinicalTrials.gov · Last updated 10 Sept 2026
Brief summary (registry, in English)
The device being studied in this research is the investigational PIB, a tool designed to measure eye pressure without touching the eye. The device uses a very low-power, eye-safe infrared light and a gentle sound signal to detect tiny movements on the white part of the eye. A camera records these movements, and a computer analyzes the information to estimate eye pressure. The test takes only a few seconds and does not require eye drops or contact with the eye. The device rests near your face using a chin and forehead support, like equipment used in an eye doctor's office. The PIB aims to provide the following possible benefits over the devices doctors may be using now including the GAT: * No touching of the eye to lower the risk of infection and discomfort * Improved accuracy and precision * Faster eye pressure measurements * Measurements that may be done by a patient at home without the need for a doctor * A low-cost eye pressure measurement device that may be used in areas where there are fewer doctors The PIB device is investigational, which means that it is not approved by the Food and Drug Administration (FDA). The GAT device has been approved by the FDA.
