Retrobulbar block before cataract surgery

Block given for local anesthesia before ophthalmic surgery.

After entering the eye perpendicular to the plane of the orbital septum, the needle is angled at 45 degrees and directed at the apex of the muscle cone.

After pulling back on the plunger to verify absence of blood, the injection of lidocaine 1% mixed with 0.375% bupivicaine is slowly injected into the muscle cone.
