Comparison of ultrasonic pachymetry, with a new optical biometry and tono-pachymetry

Medicine Science, 2017
The aim of this study was to compare the measurements of central corneal thickness (CCT) using the CT-1P tonopachymetry and AL-Scan optical biometry with those obtained with ultrasound (US) pachymetry. In this prospective study, CCTs were measured in 100

Correlation of vitreous chamber depth with ocular biometry in high axial myopia

Indian Journal of Ophthalmology, 2022
Purpose: The proportion of axial length (AL) occupied by vitreous chamber depth (VCD), or VCD:AL, consistently correlates to ocular biometry in the general population. Relation of VCD:AL to ocular biometry in high myopia is not known. The purpose of this
