Evaluation of Immersion Ultrasound Biometry in Eyes That Cannot Be Measured by Partial Coherence Interferometry

Optical biometry using partial coherence interferometry prior to cataract surgery

Immersion A-scan compared with partial coherence interferometry: outcomes analysis.

PURPOSE To compare 2 methods of axial length measurement, immersion ultrasonography and partial coherence interferometry, and to elucidate surgical outcomes based on immersion measurements. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS Axial length measurements in 50 cataractous eyes were obtained by optical biometry (IOLMaster, Zeiss Humphrey Systems) and immersion ultrasound ...

Partial Coherence Laser Interferometry in Highly Myopic versus Emmetropic Eyes

PURPOSE To investigate the reliability of partial coherence laser interferometry for optical biometry in highly myopic eyes. METHODS Axial length measurements by the IOLMaster (Carl Zeiss Meditec, Germany) with signal-to-noise ratio (SNR) ≥2 were performed in 52 consecutive myopic subjects with axial length ≥26.5 mm and 45 emmetropic patients before cataract surgery. Axial length measurements...

Meta-analysis of optical low-coherence reflectometry versus partial coherence interferometry biometry

A 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, Embase, China Knowledge Resource Integrated Database a...

Comparison of IOL--master and ultrasound biometry in preoperative intra ocular lens (IOL) power calculation.

Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master). The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial coherence laser interferometry.40 eyes were included...
