Anterior Segment Variations After Cataract Surgery in Subjects with Primary Open-Angle Glaucoma

Year: 2026

Type: article

Abstract: Background: The impact of cataract surgery on anterior segment structures in subjects affected by primary open-angle glaucoma (POAG) remains incompletely understood. The aim of this study was to characterize changes in anterior segment parameters after cataract surgery in POAG subjects compared with non-glaucoma subjects (control). Methods: A prospective comparative study was conducted, including patients scheduled for cataract surgery who underwent a comprehensive ophthalmic examination before and after surgery using anterior segment optical coherence tomography (OCT). Longitudinal changes and between-group comparisons were analyzed. Results: The results demonstrated a significant enlargement of the anterior chamber and iridocorneal angles after surgery in both groups (p < 0.05), with no significant differences between POAG and control eyes (p > 0.05). Several preoperative parameters, particularly angle-related metrics, were correlated with postoperative anatomical changes, suggesting their potential role as predictors of anterior segment variation (R > 0.50; p < 0.05). Conclusions: In conclusion, this study provides a detailed characterization of anterior segment changes in POAG subjects following cataract surgery, demonstrating anterior chamber enlargement comparable to that observed in non-glaucoma eyes, which may assist clinicians in the management of glaucoma.
