Summary: Purpose: To compare central corneal thickness (CCT) measurement results obtained by means of optical and ultrasonic methods.
Setting: Department of Ophthalmology, District Railway Hospital in Katowice, Poland
Methods: CCT measurement was performed in 35 eyes (18 patients). All patients undergone exams with use of an ultrasonic pachymeter – Pocket II (Quantel Medical), a specular microscope – Topcon SP-2000P (Topcon America Corporation) and an optical coherence tomography (OCT) system – Visante OCT (Carl Zeiss Meditec). All exams were carried out 3 times during the same visit, by one investigator.
Results: Mean CCT was 535.72 µm ±23.36 (SD) Visante OCT, 538.42 µm ± 25.27 (SD) with the ultrasonic device and 522.28 µm ± 23.37 (SD) with the specular microscope. Visante OCT had the highest reproducibility – mean difference between measurements was 3 microns. The difference between results obtained by means of OCT/USG and spectral microscopy was statistically significant (p<0.05).
Conclusions: Visante OCT seems to be a very reliable device to measure CCT, especially as obtained results are only very slightly influenced by an investigator.

Keywords: Central corneal thickness, ultrasonic pachymetry, specular microscopy, Visante OCT.
