Purpose To estimate anterior chamber morphometric parameters (depth and volume) in case of patients they who underwent cataract surgery with posterior intraocular lens and capsular tension ring (CTR) implantation, using Anterior Segment OCT (OCT Visante) and ultrasound biomicroscopy (UBM). Methods Studied group consisted of 23 persons 12 women and 11 men, aged from 79 to 52 years old (mean 63.9 years). BCVA ranged from 0.2 to 1.0 (mean 0.6). Anterior chamber depth and width were measured at first using Anterior Segment OCT (OCT Visante) than with the use of ultrasound biomicroscopy (UBM ). Anterior chamber volume was calculated. Results Anterior chamber depth measured using Visante OCT ranged from 4.34mm to 4.79mm ( mean 4.61 ± 0.17) and in case of UBM ranged from 4.17mm to 4.92mm ( mean 4.57 ±0.28). Anterior chamber volume measured using Visante OCT ranged from 230,42µl to 339,91µl ( mean 278,2 ± 31,32) and in case of UBM ranged from 212,75µl to 330,51µl ( mean 269,23 ±36,77). Conclusion Anterior Segment OCT is more precise in anterior chamber estimation also allows to enlarge measured area. As a non contact device is easier and faster to performe, however picture’s width in case of ultrasound biomicroscopy is larger.
