Optical variables measurement

A non-invasive dual-functional eye measurement system is developed by integrating spectral domain optical coherence tomography (SD-OCT) system with an optical reflectometer. The integrated system measures anterior segment of the eye as commonly performed by a SD-OCT while at the same time provides high resolution evaluation of tear film thickness and tear thinning dynamics. 6 μm axial resolution for anterior segment imaging and high resolution of 21nm for tear film thickness measurement are achieved. The present minimum measured tear film thickness is 0.3 μm. As a phantom study, a model eye with artificial tear film is evaluated using the integrated OCT/reflectometer device.
