Abstract

Aim: To compare corneal power calculated by IOL master and manual keratometry.

Material & methods: A prospective, consecutive, comparative & single-centre study was done in pre cataract surgery work up patients. Manual keratometry was done using Keratometer KMS-6 (Appasamy Associates, India) while automated keratometry was done with IOL master 500 (Carl Zeiss Meditec, Jena, Germany). SPSS version 20.0 was used for statistical analysis.

Results: Overall agreement between two methods was excellent for horizontal corneal diopteric power (kappa = 0.53 ) & good for vertical corneal diopteric power (kappa = 0.46) using bland-altman analysis.

Conclusion: Manual keratometry is still relevant in the era of digital automated keratometry measured by IOL master.
