Eye shape using partial coherence interferometry, autorefraction, and SD-OCT. [PDF]

Optom Vis Sci, 2015
Peripheral refraction and retinal shape may influence refractive development. Peripheral refraction has been shown to have a high degree of variability and can take considerable time to perform. Spectral domain optical coherence tomography (SD-OCT) and peripheral axial length measures may be more reliable, assuming that the retinal position is more ...

Comparison of a new biometer using swept-source optical coherence tomography and a conventional biometer using partial coherence interferometry. [PDF]

PLoS ONE, 2018
The aim of this study was to compare the axial lengths (ALs) using a new biometer with swept-source optical coherence tomography (Argos) versus ALs using a conventional biometer with partial coherence interferometry (IOL Master, version 5). The ALs in 48

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

Biomed 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).
