Comparison of the Optical Biometry Based on Swept-Source Optical Coherence Tomography and Ultrasound-Based Biometry Device in Patients With Mature Cataract

International Journal of Clinical Practice
Conclusion: AL and ACD measurements from the optical biometry based on swept-source OCT and ultrasound can be used interchangeably in patients with mature cataract. However, LT measurements from the two devices should not be considered interchangeable.

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 ...

Comparison of applanation ultrasound biometry with optical biometry for intraocular lens power estimation in cataract surgery and their impact on prediction error

Kerala Journal of Ophthalmology, 2021
Aim: The aim of this study is to determine the agreement between applanation ultrasound biometry (AUB) and optical biometry using Lenstar 900 for precataract surgery axial length measurement and intraocular lens (IOL) power estimation and their effect on

Optical Biometry versus Ultrasonic Biometry in Intraocular Lens Power Calculations in High Axial Myopia [PDF]

Al-Azhar International Medical Journal, 2023
Background: IOL implantation is now seen as a type of refractive surgery rather than merely being used to improve visual rehabilitation. In this context, accurate pre-operative biometric measurement is a crucial requirement.Aim of the work: comparing the

Ocular Biometry OCR: a machine learning algorithm leveraging optical character recognition to extract intra ocular lens biometry measurements [PDF]

Frontiers in Artificial Intelligence
Given close relationships between ocular structure and ophthalmic disease, ocular biometry measurements (including axial length, lens thickness, anterior chamber depth, and keratometry values) may be leveraged as features in the prediction of eye ...

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

Refractive surprise after cataract surgery secondary to smeared optics of swept-source optical coherence tomography biometer: a case report

BMC Ophthalmology, 2020
Background Inaccurate biometry can lead to the wrong intraocular lens implantation and result in refractive surprise following cataract surgery. It is important to be sceptical of biometry results that do not match the refractive or clinical picture and ...
