N2 - 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 wound. Additionally, stromal edema and iris features were clearly imaged with the device. SD-OCT can be used to analyze clear corneal incisions to determine optimal wound construction technique and geometry as they relate to the prevention of complications such as postoperative wound leak, infection, and epithelial ingrowth.
