Abstract
PURPOSE: The purpose of this study was to compare intraocular pressure measurements obtained with XPERT, an upgraded model of the noncontact tonometer, with those from Goldmann applanation tonometry. METHODS: An average of three intraocular pressure measurements, generated by the XPERT, was compared with a single reading from a Goldmann applanation tonometer in 421 eyes of 220 patients. RESULTS: The standard deviation of the matched-pair differences (Sdiff) for the entire population was 2.3 mm Hg, whereas in a subset of 95 eyes with intraocular pressures of > or = 20 mm Hg by Goldmann applanation tonometry, the Sdiff was 3.3 mm Hg. CONCLUSIONS: The XPERT was found to provide reliable intraocular pressure measurements, especially within the normal range.
