Sir,

I read with interest the article by Can et al.[1] on “Comparison of central corneal thickness measurements using different imaging devices and ultrasound pachymetry”.

In the methods section, it is mentioned that three consecutive central corneal thickness (CCT) measurements were taken with the non-contact devices. For the ultrasonic pachymetry (UP) measurement, the number of measurements performed was not mentioned. Was it a mean of three measurements or mean of nine measurements, as recommended by the manufacturer for this UP (PachPen; Accutome Inc, Malvern, PA)?

The authors have measured intra-session intra-operator repeatability for AL-scan measured CCT measurements. For the other three devices intra-observer repeatability for CCT measurements was not measured and they have mentioned that it has been evaluated before in other publications. However, the references for the same is not provided. Also, as the UP is being compared with the 3 non-contact devices and UP measurements are highly operator dependent, it would have been useful to obtain intra-operator, intra-session repeatability of CCT measurements for the UP.
