Role of Optical Coherence Tomography on Corneal Surface Laser Ablation [PDF]

, 2012
This paper focuses on reviewing the roles of optical coherence tomography (OCT) on corneal surface laser ablation procedures. OCT is an optical imaging modality that uses low-coherence interferometry to provide noninvasive cross-sectional imaging of ...

Central Corneal Thickness Measurements With Different Imaging Devices: Ultrasound Pachymetry, Noncontact Specular Microscopy and Tono-pachymetry

Beyoglu Eye Journal, 2022
Investigation of the compatibility between central corneal thickness (CCT) measurements in healthy eyes by comparing standard ultrasound pachymetry (USP) with noncontact tono-pachymetry (NCT) and specular microscopy (SM) devices was aimed.Forty-five eyes of 45 healthy volunteers aged between 18 and 60 years were included in this study. CCT of all cases
