Low IOP is measured with great accuracy using non-contact applanation tonometer

A non-contact applanation tonometer (Ocular Response Analyzer, Reichert) appears to be more effective than the Goldmann applanation tonometer (GAT) in assessing very low and negative IOP values using the non-contact applanation tonometer's corneal-compensated IOP (IOPcc) parameter. The GAT may be the long-accepted gold standard, but the more accurate assessment of IOP using the non-contact applanation tonometer challenges this gold standard and raises questions as to which of the two techniques is optimal in measuring IOP.
