Refractive Results Using a New Optical Biometry Device: Comparison With Ultrasound Biometry Data. [PDF]

open access: yesMedicine (Baltimore), 2015
The aim of the study was to compare the measurements of optical (AL-Scan; Nidek Co., Ltd.) and ultrasonic (Echo Scan US-800; Nidek Co., Ltd.) biometry devices and to assess refractive results after cataract surgery. Eighty-one cataractous eyes of 81 patients were included in this study.

Ocular Biometry OCR: a machine learning algorithm leveraging optical character recognition to extract intra ocular lens biometry measurements [PDF]

open access: yesFrontiers in Artificial Intelligence
Given close relationships between ocular structure and ophthalmic disease, ocular biometry measurements (including axial length, lens thickness, anterior chamber depth, and keratometry values) may be leveraged as features in the prediction of eye ...

Comparison of optical biometry versus ultrasound biometry in different axial length groups. [PDF]

open access: yesSaudi J Ophthalmol
Abstract PURPOSE: The accuracy of optical biometry is higher than ocular ultrasound, but it is expensive and has limitations in patients with dense cataracts. On the other hand, ocular ultrasound biometry is still a frequently used technique in most developing countries due to its lower cost.
