Extended in vivo anterior eye-segment imaging with full-range complex spectral domain optical coherence tomography

Abstract

In conclusion, we have developed a SD-OCT system with an extended depth range. With the high sensitivity and high speed of the instrument, the whole anterior eye segment from the cornea to the posterior surface of the lens could be imaged in vivo with a recording time of $\sim 100\mathrm{ms}$ per B scan at an A scan rate of $20\mathrm{kHz}$ ; 120 sequenced B scans formed a 3-D scan, which was recorded in $\sim 15\mathrm{s}$ . Possible clinical applications of our system may be in cataract and glaucoma (chamber angle) diagnostics, as well as in accommodation studies.
