Aim: The aim of this study was to evaluate measurements of the central corneal thickness using OLCR and ultrasound pachymetry (IOPac). Materials and Methods: In a retrospective observational study, fifty patients were assessed. Central corneal thickness was measured using OLCR and ultrasound. Results: The IOPac system shows results for the central corneal thickness between 419 (mu)m and 613 (mu)m. The OLCR values ranged between 421 and 598 (mu)m. The coefficient of variation was 1.12% in the case of the IOPac and 0.97% in the case of the OLCR. The paired Student's t-test showed no significant differences between the two methods. The agreement between the two methods was high with r = 0.929. Conclusions: The agreement between the results for the central corneal thickness using OLCR and ultrasound is high. The OLCR is a non-touch technology that does not require local anaesthesia, thus further reducing the risk of infection or mechanical trauma. Especially in surgical applications or glaucoma assessments, movement artefacts need to be ruled out, which potentially could cause wrong values and thus lead to wrong decisions.
