Paper Abstract

Spectral domain optical coherence tomography (SD-OCT) was developed in order to image the anterior segment of human eye. The optical path at reference arm was switched to compensate the sensitivity drop in OCT images. An scan depth of 12.28 mm and an axial resolution of 12.8 μm in air were achieved. The anterior segment from cornea to posterior surface of crystalline lens was clearly imaged and measured using this system. A custom designed Badal optometer was coupled into the sample arm to induce the accommodation, and the movement of crystalline lens was traced after the image registration. Our research demonstrates that SD-OCT with ultra-long scan depth can be used to image the human eye for accommodation research.
