title = "Optical Coherence Tomography Assessment of Angle Anatomy Changes After Cataract Surgery",
abstract = "Purpose: To evaluate changes in anterior chamber (AC) morphology induced by cataract extraction using anterior segment optical coherence tomography (OCT). Design: Prospective comparative observational case series. Methods: Thirty-two eyes of 32 patients underwent OCT imaging of the angle before and after cataract surgery. Anterior chamber depth (ACD), angle opening distance at 500 μm (AOD500) and trabecular-iris space at 500 μm (TISA500) were measured pre- and postoperatively. Preoperative lens thickness (LT) and lens position (LP) were calculated. Results: ACD, AOD500, and TISA500 increased significantly after cataract extraction (P < .001). Preoperatively, ACD and LT highly correlated (P = .0083) as did ACD and TISA500 (P = .0001). TISA500 correlated with LP (P = .0001) but not with LT (P = .74). Conclusions: Changes in angle morphology after cataract surgery can be imaged and objectively quantified by anterior segment OCT. Lens position may have a greater influence on angle width than LT.",
