Acoustic and optical biometry

Acta Ophthalmologica
Ocular biometry is a diagnostic method in ophthalmology that uses various techniques to measure the different parts of the eye. It involves the use of instruments that can measure the axial length of the eye, corneal curvature, anterior chamber depth, and other parameters related to the eye's structure.

Accuracy of the Postoperative Refractive Prediction in Optical Biometry Versus Ultrasound Biometry in Preoperative Intraocular Lens Power Calculation

Journal of Advances in Medicine and Medical Research, 2022
Background: Contact A-scan ultrasonic biometry is the most frequently utilized technique for determining axial length (AXL). Optical biometry is a technique that utilises partial coherence interferometry to determine ocular biometry parameters.
