Eye Irrigation

Eye Irrigation Opener.jpeg

This module describes how to irrigate the eye to treat superficial foreign bodies, or chemical or thermal eye injuries.


  1. Chemical or thermal injury to the eye

  2. Superficial foreign body


  1. Suspected penetrating eye injury

  2. Penetrating foreign body


Always verify your patient’s identity and obtain informed consent before proceeding.

How do I explain this procedure?

“I need to rinse out your eye to remove what is irritating it.”

What can my patient expect?

“I’ll give you an eye drop to reduce pain, and then I’ll rinse your eye with lots of water. It will be a little uncomfortable, but it’s important to prevent further injury to your eye. I’ll also lift up your eyelids so that the water washes away anything stuck there.”

What is my patient’s role?

“Tell me if you have any allergies. Try not to squeeze your eye shut, stay relaxed and let me keep rinsing the eye, even if it’s uncomfortable. Afterwards, avoid touching the eye. I will give you sterile gauze packs to wipe around your eye if necessary. Always wash your hands beforehand and throw away the gauze immediately.”

Documentation

  1. Patient notes

  2. If injury on duty, use appropriate documentation

Equipment

  1. Alcohol-based hand rub

  2. Local anaesthetic:

  3. An IV giving set

  4. Normal saline bags (several litres may be necessary for gross contamination of the eye)

  5. A bowl and linen saver to catch water

  6. Cotton-tipped applicators (earbuds)

  7. If available,

    OR

  8. Winged set (butterfly needle) to

    your own eye irrigator and plaster strips to attach irrigator to skin

  9. Sterile eye pad

  10. For chemical injuries,

    (at least two pieces)

  11. For chemical injuries, use eye protection, gloves and an apron


Position the patient with the affected eye closest to the ground to avoid contaminating the unaffected eye.


Follow medical asepsis without gloves.

  1. Perform hand hygiene. Don any PPE required.

  2. For chemical injuries, touch the

    to the lower fornix of the eye.

  3. Apply local anaesthetic:

    a drop of proparacaine to the eye.

  4. For particulate matter, sweep the ocular surface and upper and lower fornices with a moistened cotton-tipped applicator.

  5. Position the linen saver and bowl under the eye.

  6. Hang the normal saline well above the patient and attach the giving set.

  7. the eyelids and irrigate the eye with the giving set, directing the stream to flow over the contour of the eye, not directly onto the cornea. Irrigate the upper and lower fornices. Do not use force such as with a syringe.

  8. If longer irrigation is desired, after using 1 L of saline, attach the

    to the giving set. Ask the patient to look down and insert under the upper lid, then perform the reverse for the lower lid. The lens should stay in place without support.

  9. For chemical injuries, irrigate for at least 20 minutes, retest the pH and

    irrigating until the pH has normalised (pH = 7).

  10. Evert the upper eyelid. Place a cotton-tipped applicator on the upper eyelid and flip the lid upwards towards the forehead. Use the applicator to hold it in place.

  11. Sweep the inside of the upper eyelid with a moistened second applicator for residual material.

  12. Repeat the sweep of the upper and lower fornices.

  13. Dispose of medical waste safely.

  14. the eye for signs of corneal abrasion or penetrating eye injury. Assess the visual acuity.

  15. Patch the eye with a sterile eye pad.

  16. Record visual acuity and completion of the procedure in patient notes.

  17. Prescribe a topical antibiotic to be used for 3 days. Refer the patient if required for

    drops to relieve ciliary spasm.


I don’t have a Morgan lens.

Use the tubing of a winged set (butterfly needle). Cut off the needle and use it to poke holes in the tubing. Tie a knot at the end of the tubing. Attach the tubing to the IV giving set. To use, place a loop of the tubing under the eyelids, well into the upper and lower fornices, and secure the tubing to the face with tape. Open the IV giving set to irrigate.

I cannot open the eyelids.

Put topical anaesthetic drops in the eye. Use eyelid retractors or make your own retractors with paperclips to open the eyelids. Clean them with an alcohol swab before insertion.

  1. Corneal abrasion

  2. Exacerbation of a penetrating eye injury

  3. Never use buffer or neutralising solutions, which can cause additional chemical reactions
