A questionnaire was sent to all Full Members of the British Association of Otolaryngologists to ascertain whether and what type of eye protection surgeons and theatre nurses wear during mastoid surgery. Despite Department of Health recommendations only 58 per cent of surgeons and 19 per cent of theatre nurses routinely wear any form of eye protection.
A technique, compatible with accelerators having independent collimators, is presented, which greatly simplifies alignment of pencil eye-lens shields. The patient is placed so that the eye to be shielded is on the central axis of the beam and the accelerator's collimators are adjusted independently to define the field. A divergent lead shield 14 cm long is suspended from a wire that hangs along the central axis from a blocking tray in its usual location. The suspension length is variable and adjusted on the first day so that the shield is about 1 cm above the patient's eye. On subsequent treatment days, the wire is simply put in place on the tray with no further adjustment required. This technique reduces setup time and makes the shield positioning highly reproducible.
