Refractive error and ocular biometry in Jordanian adults
Ophthalmic and Physiological Optics, 2005Abstract The aim of this study was to establish the prevalence of refractive errors in Jordanian adults of working age, and to study the ocular biometric correlates of refractive error in this population. Refractive error and ocular biometry were measured in 1093 Jordanian adult subjects aged 17–40 years to determine the prevalence of

Association of refraction and ocular biometry in highly myopic eyes
Australasian journal of optometry, The, 2021 Clinical relevance: Ocular biometry is key to understanding the determinants of ocular development and pathology changes, especially for the thriving myopic population in Asia. Investigating biometric data in highly myopic eyes within a wide age spectrum

Ocular biometry of the cynomolgus monkey
Current Eye Research, 1981Eight cynomolgus monkeys underwent ocular biometry. Body weight = 3.04 +/- 0.59 kg; horizontal corneal diameter = 9.79 +/- 0.47 mm; anterior corneal curvature = 59.20 +/- 1.51 diopters at 90 degrees, 58.81 +/- 2.18 diopters at 180 degrees, 0.40 +/- 1.03 diopters at 90 degrees-180 degrees; anterior chamber depth = 2.79 +/- 0.27 mm; lens thickness = 3.18

A review on ocular biometrie research
2017 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2017Biometrics is the one of the important technique of identity science for recognition of individual based on their physiological or behavioral trait. Recognition is achieved by the identity of different parts of human body. Iris recognition is the most trustworthy biometric due to rich texture and permanence in cooperative environment but in ...

Comparison of a new optical biometry with an optical low-coherence reflectometry for ocular biometry
Contact Lens and Anterior Eye, 2016To evaluate the repeatability and agreement of a new partial coherence interferometry optical biometer (AL-Scan, Nidek CO, Aichi, Japan) with optical low-coherence reflectometry device (Lenstar LS 900, Haag-Streit AG, Köniz, Switzerland).Three consecutive measurements with the 2 devices were performed by the same examiner in 65 eyes of 65 patients with

A New Device for Ocular Biometry
1981Measuring the eye length and its different parts is of interest for several ophthalmological questions. Nowadays the ultrasonic biometry is very often used, as it is the only simple method to get information about the different axial distances of the eye.

Accuracy Considerations in the Ultrasonic Ocular Biometry
1975Ocular biometry requires unusually high levels of accuracy in order to permit refractive corrections to be based on measurements of ocular dimensions. Keratoprosthesis, lens implants, aniseikonic lenses as well as physiological correlations all require an accuracy of the order of a fraction of a millimeter.

[Ocular biometry using Orbscan].
Journal francais d'ophtalmologie, 2005Orbscan is a recent optical device that combines the Placido disk of the videokeratoscope and a scanning slit. The scanning slit measures the elevation of both the corneal surface (anterior and posterior) and the anterior iris-lens surface. Biometric measures of the anterior segment such as corneal thickness, anterior chamber depth, corneal diameter ...
