Abstract

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 and Wanfang Data. A total of 18 studies involving 1921 eyes were included. There were no statistically significant differences in axial length (mean difference [MD] 0 mm; 95% confidence interval (CI)-0.08 to 0.08 mm; p = 0.92), anterior chamber depth (MD 0.02 mm; 95% CI-0.07 to 0.10 mm; p = 0.67), flat keratometry (MD-0.05 D; 95% CI-0.16 to 0.06 D; p = 0.39), steep keratometry (MD-0.09 D; 95% CI-0.20 to 0.03 D; p = 0.13), and mean keratometry (MD-0.15 D; 95% CI-0.30 to 0.00 D; p = 0.05). The white to white distance showed a statistically significant difference (MD-0.14 mm; 95% CI-0.25 to-0.02 mm; p = 0.02). In conclusion, there was no difference in the comparison of AL, ACD and keratometry readings between the Lenstar and IOLMaster. However the WTW distance indicated a statistically significant difference between the two devices. Apart from the WTW distance, measurements for AL, ACD and keratometry readings may be used interchangeability with both devices.
