Iop correction pachymetry
WebSingh et al suggested that the effect was small and probably not relevant for most patients. 29 Conversely, a recent report suggested that a correction for corneal effects might be needed for some groups of patients. 5 In a literature review, Doughty and Zaman reported a mean CCT of 544 (SD 34) μm for measurements made by ultrasound pachymetry. 30 … Webiop CCT By combining soft air puffing, 3D auto-tracking, and a Scheimpflug camera, TOP-1000 delivers excellent IOP measurements that are corrected for central corneal thickness.
