Eye ointment Tissues

Recommended Practice

Explain procedure to the patient. Wash hands and perform eye toilet if necessary. At the bedside, check the eye ointment with another nurse (or in the case of mydriatics,with a Registered Nurse) against the written order on the drug chart to ensure: correctmedication correct patient (identify patient verbally and with wrist band) correct eye check expiry date correct order (if more than one medication)

Before applying ointment to patients eye, squeeze small amount of ointment onto a clean

tissue, ensuring tip does not contact tissue. Ask the patient to look upwards. Gently draw down the lower lid, place 1cm of ointmentalong the margin of the lower lid. Do not touch the eye or eyelid with the tip of the ointmenttube. Ask the patient to close eyes for one minute, and remove any excess ointment from eyelidwith a tissue. Use a clean tissue for each eye. Cleanse excess ointment from the tube with a tissue and then replace cap. Discard any used articles.

Summary

Question

What is the evidence on administration of ocular medication?

Clinical Bottom Line

Ocular medications are most commonly delivered in the form of topical ointment or drops.Topical ophthalmic treatment is commonly prescribed to treat existing conditions, prevent ortreat infection or inflammation, and to promote comfort and prevent damage to ocularstructures.1 Treatment may be short or long term.

It is suggested that one drop instilled into the lower fornix is adequate since the eye cannotcope with anymore fluid and will overflow and exit via the nasolacrimal drainage channels.1

(Level IV) Eye ointment should be applied to the upper rim of the inferior fornix in a 2cm line startingfrom the nasal canthus. 1 (Level IV) Drops should be instilled before ointment is applied, as ointment 'waterproofs' the eye.Ideally five minutes should be left between drops to the same eye otherwise the previous

drops will be washed away and not absorbed.

(Level IV) Adverse systemic effects can be minimised by asking patients to close their eyes gentlyand count to 60 after the instillation of drops. This prevents the drop being moved onto thenasolacrimal system where it would be unavailable for absorption.1 (Level IV) Descriptive studies suggest that in the clinical environment eye medications are frequentlykept on bedside lockers, rather than in the medication trolley or drug cupboard, and areoften not given at the prescribed time or are not prescribed when the patient is admitted tohospital.1 (Level IV) Topical ophthalmic therapy is prescribed at a frequency designed to allow optimumconcentration of drugs into the ocular tissues to produce an optimum therapeutic effect.Changes in the interval between drops or ointment and missed doses can reduce theeffectiveness of therapy.1 (Level IV) Eye drops facilitate absorption of medication but are suggested to have a shorter durationof action than ointments.2 (Level IV)

The efficacy of eye drops relates primarily to the volume of solution delivered and thecapacity of the conjunctival sac. Viscous solutions have delayed absorption rates, extendingthe therapeutic effects for longer periods than water-soluble drops. 2 (Level IV) Informed consent should be obtained prior to administering ocular medications. 2 (Level IV) All ocular medications should be checked against the prescription order to ensure thecorrect drug and strength is administered to the correct eye. 2 (Level IV) The literature recommended checking the expiry date and examining the solution/ointmentfor any abnormalities. Thorough hand washing was recommended prior to removing the cap

from ocular solutions or ointments to avoid cap and container contamination.3 (Level IV) Position the patient to lay supine or in a chair with the head slightly tilted back and the chinupwards.4 (Level IV) Hyperextension of the neck should not occur in patients with cervical spine injuries. 4

(Level IV) Gently displacing the lower eyelid (inferior fornix) downward opens the conjunctival sac andthe medication drop may be directed into this space. Medication used for corneal lubricationand anaesthetic drops are the exception for this technique. Application of drops onto thecornea is associated with increased patient discomfort and reduced efficacy.2 (Level IV) The delivery of ocular medications may result in systemic absorption and this posesinherent risks. 4 (Level IV) Topical ophthalmic medication administration is best suited for treatment of the cornea,conjunctiva, anterior segment structures and the ciliary body.5 (Level IV) It is also recommended that ointments or gels be inserted last, as they have extendedabsorption times. Post-administration assessment for systemic and local adverse effects

was suggested on commencement of new or multiple ocular medications, or where thenurse is unfamiliar with the patient or the medication.6 (Level IV) Nursing staff should understand the likely duration of treatment to help ensure that patientsdo not discontinue important therapy or are not given repeat prescriptions for unnecessarymedications.1 (Level IV) Many patients do not use eye drops as prescribed for Glaucoma for reasons includingforgetfulness, being prescribed a large number of medications, difficulty instilling the drops,busy lifestyle, and not understanding the benefits.7 (Level I) People who wear contact lenses should avoid drops with preservatives as they increasecorneal contact time and may lead to corneal toxicity.8 (Level IV) Ocular medication is governed by the same controls as medications delivered via otherroutes.8 (Level IV) When two or more ocular medications are prescribed, there should be a 3-5 minute interval

between instillations in the same eye.8 (Level IV) Side effects of ocular medications include headaches, lack of focus, dryness, irritation,allergy, disorientation, mental confusion, shortness of breath and hallucinations.8 (Level IV)Patients receiving corticosteroid eye drops should be reviewed as there is a risk ofdeveloping steroid-induced glaucoma. There are also risks of secondary infection, cornealthinning, and possible corneal perforation.8 (Level IV)

Best Practice Recommendations

Caution should be taken regarding eye drops since they may have adverse systemiceffects, and patients can experience allergic reactions to some ophthalmic treatments.(Grade B) Nurses must take responsibility for knowing the effects and side effects of treatment,including interactions with systemic medication. (Grade B)
