During an eye irrigation, which instruction is correct?

• A. Irrigate toward the outer surface of the lower eyelid
• B. Hold the syringe 2 inches from the eye
• C. Irrigate directly at the corneal surface
• D. Irrigate toward the inside surface of the lower eyelid and from the inner to outer corner

Answer: (D)

During an eye irrigation, the goal is to wash debris across the surface of the eye without contacting the cornea directly. Directing the stream toward the inner surface of the lower eyelid and sweeping from the inner corner toward the outer corner carries the fluid across the conjunctival surface and toward the outer canthus. This technique helps debris move across the eye and drain away from the lacrimal puncta, reducing irritation and the chance of backflow. Irrigating toward the corneal surface or aiming at the outer eyelid, or relying on an improper distance, risks touching the cornea or missing debris, making the irrigation less safe and effective.
