Paper Abstract

Motion artefacts in traditional scanning spot optical coherence tomography (OCT) anterior-segment imaging can hamper the application of OCT to the determination of refractive properties of ocular interfaces. To overcome this problem, we have developed a Hyperparallel spectral domain approach (HP-OCT) for high speed volumetric imaging (up to 300k Ascan/ s). We demonstrate a repeatability of better than 0.1 Diopters for in-vivo anterior and posterior corneal power measurements as well as providing biometric measurements such as axial length, pachymetry, lens thickness and curvature, anterior chamber depth and axial length.
