The Optimal IOP for the Stable Anterior Chamber in Cataract Surgery

Dr. Hisaharu Suzuki and colleagues discuss how to obtain the optimal IOP to avoid destabilizing the anterior chamber during phacoemulsification, in this video which won the European Society of Cataract and Refractive Surgery's Michael Blumenthal Award. In their research, the combination of pressurized perfusion via a peristaltic pump and a handpiece with an attached pressure perfusion sensor led to the smallest anterior chamber depth and pressure. However, there were cases where the posterior capsule elevates due to either the impact of the vitreous body or external pressure on the eye; in those cases, the IOP should be adjusted according to the patient and stage of surgery.
