Validation of a partial coherence interferometry method for estimating retinal shape. [PDF]

open access: yesBiomed Opt Express, 2015
To validate a simple partial coherence interferometry (PCI) based retinal shape method, estimates of retinal shape were determined in 60 young adults using off-axis PCI, with three stages of modeling using variants of the Le Grand model eye, and magnetic resonance imaging (MRI).

Technical failure rates for biometry between swept-source and older-generation optical coherence methods: a review and meta-analysis

open access: yesBMC Ophthalmology, 2023
Purpose Precise ocular measurements are fundamental for achieving excellent target refraction following both cataract surgery and refractive lens exchange. Biometry devices with swept-source optical coherence tomography (SS-OCT) employ longer wavelengths

Meta-analysis of optical low-coherence reflectometry versus partial coherence interferometry biometry. [PDF]

open access: yesSci Rep, 2017
AbstractA meta-analysis to compare ocular biometry measured by optical low-coherence reflectometry (Lenstar LS900; Haag Streit) and partial coherence interferometry (the IOLMaster optical biometer; Carl Zeiss Meditec). A systematic literature search was conducted for articles published up to August 6th 2015 in the Cochrane Library, PubMed, Medline ...
