Abstract

A method and system for evaluation tear film thickness and thinning dynamics in an eye with or without wearing a contact lens using a specially configured optical reflectometer. The method and system may address the beam aiming flexibility on the tear film surface by incorporation of a galvanometer scanner with the fiber coupled optical reflectometer. The tear film thickness, tear film thinning dynamics, and tear film breakup thickness can be determined. The system can also be combined with spectral domain OCT or swept source OCT for ophthalmology applications. The advantage is fast and high precision tear film evaluation that can also be extended to water film on contact lens evaluation for the determination of contact lens hydrophilic properties.
