1. Three-Dimensional Spectral Domain Optical Coherence Tomography of a Clear Corneal Cataract Incision

    A prototype 1,310-nm wavelength spectral domain optical coherence tomography (SD-OCT) instrument was constructed and mounted onto a conventional slit lamp for imaging of the anterior segment. The device had an axial resolution of 8 µm and was able to acquire real-time two-dimensional images at 14 frames/second and full three-dimensional datasets in approximately 7 seconds. An SD-OCT dataset of 100 B-scans, each consisting of 512 A-scans, was acquired from the left eye of a patient who had undergone phacoemulsification with a clear corneal incision. The resulting dataset could be manipulated in three-dimensional space to analyze the geometry of the ...
