Highly Parallelized Optical Coherence Tomography for Ocular metrology and imaging

摘要

Motion artefacts in traditional scanning spot optical coherence tomography (OCT) anterior-segment imaging can hamperthe application of OCT to the determination of refractive properties of ocular interfaces. To overcome this problem, wehave 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 powermeasurements as well as providing biometric measurements such as axial length, pachymetry, lens thickness andcurvature, anterior chamber depth and axial length.
