Correlate A-scan, biometry measurements to improve accuracy in IOL calculations A case shows how disparate measurements can lead to an incorrect IOL power calculation. Issue: February 25, 2020.

Optical biometry was unable to penetrate the opaque lens, so ultrasound A-scan was used to measure the eye, and the lens thickness was confirmed to be 6.34 mm, which is an increase of 40%.

To compare the accuracy and reliability of intraocular lens (IOL) master and A-scan immersion biometry in silicone oil (SO)-filled eyes. A prospective, consecutive, nonrandomized study was ...

Kunavisarut et al 1 should be congratulated on their study ‘Accuracy and reliability of IOL master and A-scan immersion biometry in silicone oil-filled eyes’. This is an important work, given ...
