Anterior Chamber Depth, Iridocorneal Angle Width And Intraocular Pressure Changes After Uneventful Phacoemulsification: Narrow Versus Open Iridocorneal Angles

Methods: In this prospective study, subjects underwent phacoemulsification with foldable lens implantation. Anterior chamber angle grading of 2 or less (Shaffer grading) in 3 or all quadrants was considered narrow angle (NA). Anterior segment optical coherence tomography and tonometry were performed preoperatively and 10 days and 1, 3, and 6 months after surgery. The ACD and angle opening distance at 500 μm anterior to the scleral spur (AOD500) were assessed from anterior segment optical coherence tomography.
