Which action is least appropriate when instilling eye drops?

• A. Place directly on the cornea
• B. Hold the eyelids apart gently
• C. Administer one drop per eye
• D. Wipe away any excess with tissue

Answer: (A)

When instilling eye drops, aim for the conjunctival sac rather than the cornea. The cornea is highly sensitive, and dropping directly onto it can cause irritation or a scratch, leading to pain and tearing that washes the medication away and reduces effectiveness. Therefore the best approach is to place the drop into the pocket formed by gently pulling down the lower eyelid (and keeping the lid protected), which keeps the medication in contact with the eye. Holding the eyelids apart gently creates the space for the drop, and administering one drop per eye ensures each eye receives the intended dose. Wiping away any excess with tissue is appropriate to prevent blurring and irritation from excess medication.
