MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202641099926 A) filed by Saveetha Institute Of Medical And Technical Sciences on August 19, 2026, for Dryeye Optobench Non Contact Tear Flim Breakup And Evaporation Dynamics Biosensor For Ocular Surface Health Screening.
Inventors include Jeevabh Arathi; Dr. R. Arangasamy; and Dr Ramya Mohan.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: This project presents the design and development of DgEye-OptoBench, a non-contact optical biosensing system created to evaluate tear film quality by analyzing break-up dynamics and evaporation behavior. The objective is to modernize ocular surface health screening through a precise, compact, and non-invasive optical bench capable of measuring tear film stability, tear evaporation rate, and surface scattering characteristics. The device incorporates a structured LED illumination module, optical sensors, a high-speed image acquisition system, and a micro controller based processing unit to quantify tear film dynamics without contacting the eye. Unlike traditional dry eye assessments that rely on subjective interpretation, Dry Eye-Opto Bench provides consistent and repeatable measurements by analyzing optical scattering, reflectance uniformity, and time varying tear film changes. Initial testing suggests improved diagnostic accuracy, enhanced repeatability, and user-friendly operation. The project bridges ophthalmic diagnostics with advanced optoelectronics, making tear film evaluation more reliable and suitable for clinics, screening camps, and research environments.
