A cannula for use in conjunction with a fluid source to irrigate a corneal surface of an eye, comprises a connector adapted to attach to the fluid source; and an elongated, hollow prong element having a proximal end supported by said connector and a distal tip opposite proximal end. The prong element includes an arcuate distal section formed in a plane along a curvature and having a fluid passageway therein that is surrounded by a sidewall with the fluid passageway being in fluid communication with the fluid source when the connector is fastened thereto. A port in the distal section of the prong extends from the fluid passageway through the sidewall whereby fluid from the fluid source may be ejected out of the port and onto the corneal surface during use.
