Abstract: BACKGROUND: The purpose of this study was to quantify the alterations in anterior chamber angle (ACA) parameters following phacoemulsification surgery. We also aim to assess changes in intraocular pressure (IOP) by comparing preoperative and postoperative measurements. Furthermore, the study explores potential associations between changes in ACA parameters and clinical outcomes, including IOP control. MATERIAL AND METHODS: A prospective observational study of ACA parameters among patients undergoing phacoemulsification surgery in North India. All patients were examined preoperatively and 1 month postoperatively using the Sirius tomographer to study ACA, anterior chamber depth (ACD), anterior chamber volume (ACV), central corneal thickness (CCT), and corneal volume (CV). IOP was assessed using the Goldmann applanation tonometer. This clinical study included 40 eyes of 40 patients. RESULTS: There is a statistically significant increase in mean ACA measurement from 47.27 ± 6.54° to 56.74 ± 4.72°, mean ACD from 2.76 ± 0.39 mm to 3.45 ± 0.39 mm, mean ACV from 160.47 ± 24.41 mm3 to 196.63 ± 23.63 mm3, mean CV from 52.92 ± 3.22 mm3 to 54.23 ± 2.86 mm3. The mean IOP measurement decreased from 17.03 ± 2.08 mm Hg preoperatively to 15.58 ± 2.92 mm Hg postoperatively and is statistically significant (p ≤ 0.001). CONCLUSION: The study provides valuable insights into quantifying ACA in the North Indian population using Scheimpflug corneal tomography. It shows a significant increase in ACA, ACD, ACV, and CV and a significant decrease in IOP following uneventful cataract surgery. These findings have implications for managing cataracts associated with glaucoma and other ocular conditions.
