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

open access: yesMedicine 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

Ocular biometry with swept-source optical coherence tomography

open access: yesJournal of cataract and refractive surgery, 2020
SS-OCT–based biometers provide repeatable and reproducible measurements in different ocular parameters. Optical biometers based on this technology are likely to become the gold standard for ocular biometry.

Ocular biometry

open access: yesKerala Journal of Ophthalmology, 2019
The evolution of cataract surgery to a refractive procedure owes a lot to the advances in the field of ocular biometry. Advanced biometry machines and choice of intraocular power formulae have hugely improved the accuracy of measurements and visual ...
