Correlations between ocular biometrics and refractive error: A systematic review and meta-analysis

Acta Ophthalmol. 2019 Dec;97(8):735-743. doi: 10.1111/aos.14208. Epub 2019 Aug 6.

Abstract

The understanding of correlations between different biometric parameters is essential for personalized eye care in the field of cataract and refractive surgery. This systematic review offers a clear overview of the previous literature assessing these correlations including a meta-analysis. The review is focused on the following five correlations: (1) axial length and refractive error; (2) anterior chamber depth and refractive error; (3) axial length and anterior chamber depth; (4) corneal power and refractive error; (5) corneal power and axial length. An expected strong correlation between axial length and refractive error was found. Correlations including corneal power were weak and might be clinically insignificant.

Keywords: anterior chamber depth; axial length; biometric correlations; biometry; corneal power; keratometry; refractive error.
