Abstract
Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power
calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master).
The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial
coherence laser interferometry.40 eyes were included in this prospective randomized trial. Twenty eyes underwent IOL
master and 20 eyes had aplanation ultrasound biometry. There were included only eyes with age-related cataract and
postoperative natural visual acuity (VA) 0.7. Visual acuity was performed 6 weeks after cataract surgery. After 6 weeks
best natural visual acuity were 0.9 (±0.1) in IOL-Master group and 0.85 (±0.15) in ultrasound biometry. The postoperative
mean absolute refractive error was 0.75 (±0.5) D for ultrasound biometry and 0.50 (±0.50) D for IOL-Master. Optical biometry
with the IOL-Master proved to be slightly more accurate than ultrasound biometry for IOL power calculation.
