Comparison of efficacy of longest, average, and shortest axial length measurements with a solid-tip ultrasound probe in predicting intraocular lens power.
The accuracy of intraocular lens power predictions was calculated for 93 eyes using the shortest, average, and longest of multiple solid-tip probe ultrasound axial length readings for each eye. Averaging the readings reduced the effect of corneal indentation. The single longest and average readings gave comparable results.
