Comparison of Central Corneal Thickness Measured by Tono-pachymetry and Ultrasound Pachymetry [PDF]

Journal of the Korean Ophthalmological Society, 2021
Purpose: We compared the accuracy of central corneal thickness (CCT) measurements according to CCT measured by noncontact Tono-pachymetry and ultrasound pachymetry (USP). Methods: CCT was measured in 90 eyes of 90 subjects by two optometrists. The CCT measurements were compared and the correlations between the measurements were analyzed.

Intraobserver reliability of contact pachymetry in children [PDF]

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2013
Central corneal thickness (CCT) is an important measurement in the treatment and management of pediatric glaucoma and potentially of refractive error, but data regarding reliability of CCT measurement in children are limited. The purpose of this study was to evaluate the reliability of CCT measurement with the use of handheld contact pachymetry in ...
