Purpose
To compare the difference in ocular biometry parameters measured using commercially available SS-OCT biometers in cataractous eyes.
Setting
Raghudeep Eye Hospita, Ahmedabad, Jaipur, India
Methods
Systematic review and meta-analysis. PubMed, Cochrane, ScienceDirect, and Google Scholar were systematically searched for studies on ocular biometry measurements in cataract patients using different SS-OCT biometers. Outcomes included differences in optical parameters across devices. The pooled means with effect size and 95% CI are reported.
Results
A total of 85 studies which altogether measured 95,216 eyes were included for the review and analysis based on the inclusion criteria. The majority of the studies employed the IOL Master 700 (n=60), followed by Anterion (n=17), OA-2000 (n=12), Argos (n=9), CASIA 2 (n=7), and Eyestar 900 (n=3). The pooled estimates of axial length (AL), anterior chamber depth (ACD), lens thickness (LT), intraocular lens (IOL) power, and keratometry (Km), except CCT, were not significantly different between the devices. The I2 was high for all parameters and there was no significant publication bias for AL, ACD, and IOL power, but publication bias was high for CCT, Km, and LT.
Conclusions
The review indicates that while there are minor differences in certain parameters, no single biometer emerged as superior to the others. Overall, all the SS-OCT biometers demonstrated similar accuracy and reliability and therefore may support the use of these biometers interchangeably.
