Figs. 11.30–11.35 Ventromedial subpalpebral lavage
(SPL) system placement. (11.30) The needle is tunnelled
through the medial aspect of the ventral eyelid. Care
is taken to avoid the inferior nasolacrimal punctum.
(11.31) The lavage footplate is pulled into position.
(11.32) The juxtaposition of the nictitating membrane
in this region reduces the risk of corneal contact with
the footplate. (11.33) The lavage system in place with
tubing secured to facial skin at several points in order
to minimise movement. (11.34) Tunnelling of the SPL
tubing under the skin on the forehead. (11.35) The
