Comparison of a new optical biometry with an optical low-coherence reflectometry for ocular biometry

Contact Lens and Anterior Eye, 2016
To 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

Celebrating 25 Years of Optical Biometry: A Milestone in Ophthalmology

Klinische Monatsblätter für Augenheilkunde
Optical biometry has fundamentally transformed cataract surgery, and 2024 marked 25 years since the introduction of the first optical biometer. In the early 1980 s, Fercher and colleagues pioneered the optical noncontact eye length measurement, leading ...
