Optical Coherence Tomography Aement of Angle Anatomy Change After Cataract urgery

Purpoe To evaluate change in anterior chamber (AC) morphology induced by cataract extraction uing anterior egment optical coherence tomography (OCT). Deign Propective comparative obervational cae erie. Method Thirty-two eye of 32 patient underwent OCT imaging of the angle before and after cataract urgery. Anterior chamber depth (ACD), angle opening ditance at 500 μm (AOD500) and trabecular-iri pace at 500 μm (TIA500) were meaured pre- and potoperatively. Preoperative len thickne (LT) and len poition (LP) were calculated. Reult ACD, AOD500, and TIA500 increaed ignificantly after cataract extraction (P < .001). Preoperatively, ACD and LT highly correlated (P = .0083) a did ACD and TIA500 (P = .0001). TIA500 correlated with LP (P = .0001) but not with LT (P = .74). Concluion Change in angle morphology after cataract urgery can be imaged and objectively quantified by anterior egment OCT. Len poition may have a greater influence on angle width than LT.
