A 47-year-old man was hammering a steel chisel without eye protection when he felt something strike his left eye an hour ago. Visual acuity is 6/60 on the left and 6/6 on the right. The left pupil is pear-shaped and points towards a small dark spot at the edge of the cornea, the anterior chamber looks shallow, and there is blood under the conjunctiva all the way round. He is nauseated and retching. He last ate two hours ago and cannot recall his last tetanus booster. Which one of the following should be done first?
