WebUltrasound pachymetry (US pachymetry) is a contact method for measuring CCT and is perhaps the most commonly used method. However, non-contact methods like scanning slit topography (Orbscan II), slit-lamp optical coherence tomography (SL-OCT), and specular microscopy are also used. WebOptical pachymetry is based on the measurement of the apparent thickness of an optical section of the cornea, and its popularity is largely based on the commercial availability of …
