Excerpt from Corneal Topography and Imaging
Synonyms, Key Words, and Related Terms: cornea, corneal imaging techniques, refractive surgery, corneal optics, topographic maps, curvature, elevation, slit-scan imaging, Orbscan corneal topography, confocal microscopy, optical coherence tomography, OCT, ultrasound biomicroscopy, UBM
Imaging techniques of the cornea are developing rapidly, mainly because of recent advances in refractive surgery. To understand the significance of new imaging techniques, the relevant principles of corneal optics are reviewed. The discussion of the most common clinical method of Placido-based corneal topography emphasizes important concepts of its clinical interpretation. The principles and clinical significance of several emerging technologies are reviewed
