Popis: Background: Cataract extraction surgery might modify the anterior segment characteristics. Two non-invasive devices that can identify these alterations include; Anterior Segment Optical Coherence Tomography [AS-OCT], and Ultrasound Biomicroscopy [UBM]. Aim of the work: This study aims to investigate the change of anterior chamber angle morphology before and after cataract extraction surgery by ASOCT and UBM devices.Patients and methods: Our study is a prospective randomized study. We included 100 Eyes with a significant cataract. Patients were randomized into four groups; Group A [25 eyes] with immature senile cataract, Group B [25 eyes] with intumescent cataract, Group C [25 eyes] with mature senile cataract, and Group D [25 eyes] with hyper mature senile cataract.Results: Our study included 100 patients with a mean age of 66.7 ± 10.6 years. A considerable rise was revealed in the angle measurements postoperative as compared with the preoperative measurements. We compared ASOCT and UBM results in all study groups either preoperative or postoperative and we found no statistically significant difference between ASOCT and UBM in the assessment of anterior chamber angle before and after cataract surgery [p-value > 0.05]. The mean IOP decreased from 20.58 mmHg preoperative to 16.5 mmHg postoperative.Conclusion: UBM and AS-OCT are helpful tools for imaging the anterior segment and performing the measurements required to determine the anterior chamber angle.
