X-PERT NCT advanced logic tonometer valuation

Int Ophthalmol. 1992 Sep;16(4-5):287-90. doi: 10.1007/BF00917977.

Abstract

The air pulsed automatic tonometer X-PERT NCT has been tested in hospitals on glaucomatous patients. This new technique avoids direct contact with the patient's eyes and therefore avoids any risk of contamination. The population studied consisted of 118 eyes of 60 patients whose intraocular pressure (I.O.P.) is measured by applanation with the Goldmann tonometer and then by the air pulsed tonometer. The average I.O.P. obtained by Goldmann tonometer is 17.5 +/- 5 mmHg while by X-PERT tonometer, the average I.O.P. is 17.4 +/- 1.5 mmHg. Statistical analysis of these data showed a very good correlation (r = 0.969) in the two methods of measurement.
