Abstract Details


To compare the results of intraocular pressure (IOP) measurement of three different tonometers, Goldmann Applanation Tonometry (GAT), Pascal Dynamic Countour Tonometry (DCT) and Keeler Pulsair EasyEye Non-Contact Tonometry (NCT) in keratoconus.


Yuzuncu Yil University, Department of Ophthalmology, Van.


Sixty-two eyes of 36 keratoconus subjects were incuded in the study. After resting for 5 minutes, patient’s IOP was measured. For all subjects, IOP measurements were taken sequentially on the same day by one experienced operator. Three sets of IOP measurements were obtained from each tonometer. Five minutes interval was given between each device.


Mean IOPs were 14.36±2.50, 13.92±2.08 and 9.70±2.81 mmHg for GAT, DCT and NCT, respectively. It was impossible to measure IOP in 4 eyes (6.45%) for DCT and in 7 eyes (11.29%) for NCT. The accordance rate was 11.30% between GAT and NCT, and was 51.29% between GAT and DCT.


NCT is not reliable for measuring intraocular pressure in keratoconus. We found the accordance between GAT and DCT.
