ABSTRACT The aim of the present work was to analyze and compare axial length and anterior chamber depth values obtained by means of IOL-Master™, immersion and applanation ultrasound. Axial length and the anterior chamber depth measurements were carried out by a single observer in 30 volunteers (n = 30; mean age, 68 ± 10.7 years of age; range 44 to 83 years) using IOLMaster™ (Zeiss Humphrey System, CA, USA), immersion and applanation ultrasound biometry. Ultrasound measurements were carried out with the Compuscan A-B Storz (San Louis, MO, USA). The IOLMaster™ provided axial length measurements that were 0.04 mm (p=0.936) and 0.13 mm (p = 0.606) higher than those from immersion and applanation ultrasound respectively. The mean difference between the optical and applanation measurements was -0.11 mm, and -0.03 mm between the optical and immersion measurements. In conclusion, there are no significant differences between IOLMaster™, immersion and applanation ultrasound axial length and anterior chamber depth values.
