The study was also performed to test whether the values obtained using each technique change in accordance with the central corneal thickness (CCT) and refractive and keratometric values.Study design: This study was a prospective study of 188 eyes of 94 healthy volunteers.Methods: IOP was measured using fGAT, nGAT and NCT. CCT, refractive values, and keratometric values were measured, and the correlations and differences in the IOP for each tonometer were investigated.Results: The mean IOP values obtained with the NCT, nGAT, and fGAT were 17.5±3.7, 12.3±2.7, and 12.5±2 mmHg. The mean CCT was 538.2±34.4 µm, the mean refractive value was 0.9±1.2 D, and the mean keratometric value was 43.5±1.5 D. NCT was positively correlated with fGAT and GAT values and was significantly higher than both the values. There were no differences between fGAT and GAT values. No correlation was observed between the CCT and keratometric and refractive values and the difference between NCT and nGAT or fGAT.Conclusion: Differences in the measurements obtained using nGAT and fGAT were insignificant (P>0.05). Both values were positively correlated with NCT measurements (r=0.354, P<0.05) and were independent of CCT, keratometry, and refraction values. nGAT appears to be suitable for use in routine clinic practice. Keywords: fluorescein, intraocular pressure, Goldmann applanation tonometry, noncontact tonometry, central corneal thickness, refractive valueErdogan HAkingol ZCam OSencan SDove Medical Pressarticlefluoresceinintraocular pressureGoldmann applanation tonometrynoncontact tonometrycentral corneal thicknessrefractive valueOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 12, Pp 2183-2188 (2018)
