The aim of the present work was to analyze and compare axial length and anterior chamber depth values obtained by means of IOLMaster ¿, 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.
