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

BMC 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

Correlation of vitreous chamber depth with ocular biometry in high axial myopia

Indian Journal of Ophthalmology, 2022
Purpose: The proportion of axial length (AL) occupied by vitreous chamber depth (VCD), or VCD:AL, consistently correlates to ocular biometry in the general population. Relation of VCD:AL to ocular biometry in high myopia is not known. The purpose of this

Optical Biometry Versus Ultrasound Biometry [PDF]

The Egyptian Journal of Hospital Medicine, 2020
Background: Implantation of an intraocular lens (IOL) is the gold standard in modern-day cataract surgery. Over the last decade, IOL power calculations have become a focal point of cataract surgery. Objective: To compare the sensitivity and specification of optical biometry and applanation ultrasound biometry in the measurement of intraocular lens ...
