Abstract

We calculated inter-examiner and intra-examiner variability in keratometry and ultrasound biometry when performed by two different examiners. The potential effect on intraocular lens power calculation was also considered. Intra-examiner variability was statistically and clinically significant for axial measurements, particularly in eyes with axial length greater than 24 mm. Thus, variability in biometric examination affected the emmetropic intraocular lens power, especially in myopic eyes.
