We report a case in which a severe corneoscleral burn occurred during phacoemulsification surgery. The equipment-tuning process was uneventful and routine surgery was expected. Severe tissue injury occurred because the anterior chamber collapsed momentarily and the phaco tip touched corneoscleral tissue. We discuss mechanisms by which this type of injury may occur and the likely cause in our case. We also suggest methods to reduce the incidence.
