IRRIGATE, INSTILL EYE DROPS, AND APPLY OINTMENTS TO THE EYE
As we well know, life revolves around our eyes. Eye injuries do happen and can
be very painful and serious. Accurate and immediate treatment can minimize pain and
may help to prevent damage to the eye. This lesson will include procedures to irrigate,
instill eye drops, and apply ointments to the eye. However, we will begin the lesson by
reviewing background information.
