AIMS To evaluate intra- and interobserver variability in measurements on normal and astigmatic corneas with keratometry and computerized videokeratography. METHODS Keratometric readings with the 10 SL/O Zeiss keratometer and topographic maps with the TMS-1 were obtained by two independent examiners on 32 normal and 33 postkeratoplasty corneas. Inter- and intraobserver coefficients of variabil...

Background. To estimate repeatability and comparability of central corneal thickness (CCT) and keratometry measurements obtained by four different devices in healthy eyes. Methods. Fifty-five healthy eyes from 55 volunteers were enrolled in this study. CCT (IOLMaster 700, Pentacam HR, and Cirrus HD-OCT) and keratometry readings (IOLMaster 700, Pentacam HR, and iDesign) were measured. For statis...

The Astigmometer is a simple accessory which is attached to a surgical microscope. It allows precise suturing of the cataract wound and reduced the amount of postoperative astigmatism at six weeks. This allowed rapid visual rehabilitation and more active patients. It obviated the removal of sutures in the postoperative period in most patients (90%). However, stable results after one year were o...
