Dynamic Contour Tonometry in Comparison to Intracameral IOP Measurements

Investigative Opthalmology & Visual Science, 2008
The purpose of the study was to examine the effect of central corneal thickness (CCT), corneal curvature, astigmatism, axial length (AL), and age on measurements with the Pascal Dynamic Contour Tonometer (DCT).In a prospective clinical trial 75 eyes of 75 patients undergoing phacoemulsification were examined.
