Which intervention would the nurse follow while administering topical medications
The administration of topical eye medications must be given the same priority and attention to safety as drugs administered by the systemic route Show
AbstractEye drops and eye ointments are the main treatment for most eye conditions and after eye surgery or surgery to the periocular structures. This article outlines the role nurses play in ensuring the safe administration of topical eye medication and that patients adhere to their treatment regimens.

IntroductionThe eyes are a vital part of the central nervous system. They convert light into electrical impulses that are transmitted to the occipital region of the brain, where they are interpreted into meaningful images. The eyes enable us to navigate our environment, see fine detail, interpret colour, and maintain our health and safety while performing everyday activities. However, little attention tends to be paid to the eyes or their surrounding structures until something goes wrong with them; Marsden and Shaw (2003) highlighted health professionals’ lack of understanding of eye conditions. Administration principlesEye drops and ointment are prescribed to treat acute or long-term eye conditions and/or the structures surrounding eyes. They are the mainstay of treatment for eye disease as they are administered directly to their site of action and are, therefore, more effective than medications administered orally. They are also used to prevent or treat infection or inflammatory conditions and, in some instances, are used to relieve discomfort or to prevent damage, such as with dry-eye treatment (Marsden, 2007). For patients to gain maximum therapeutic effect, it is imperative that topical eye medication is given the same priority as medications that are administered systemically. The standards governing the administration of topical eye treatments are exactly the same as those covering other routes of administration; professional guidance on the administration of medicines is available from both the Nursing and Midwifery Council (2010) and the Royal College of Nursing (2013). Nurses, patients and carers need a good knowledge and understanding of the therapeutic effects and potential side-effects of the topical drugs they administer. They must also be familiar with potential drug interactions that can occur between different types of eye drops and ointment, and also between these and drugs delivered by any other route (Andrews, 2006) - as an example, timolol eye drops may interact with insulin. Administering drops and ointmentEye drops and ointment should be administered:
Some eye drops have a long-acting effect on the pupil so it is vital they are instilled into the correct eye. For example, atropine 1% makes the eye light sensitive as the pupil will not contract in bright light. Administration procedures are stated in Boxes 1 and 2. Box 1. Procedure for instilling eye drop
Closed eye technique Alster et al (2000) recommended a technique for patients who find it difficult to have drops instilled directly into the eye, for example, children or older people:
Box 2. Procedure for applying eye ointment
It is vital to establish the patient is not allergic to any of the eye drops or ointment ingredients. Before instilling these, the eye and eyelids should be examined for signs of improvement or deterioration. In case of the latter, medical help should be sought without delay. Systemic absorptionSystemic absorption (SA) of eye drops and ointments occurs via the conjunctival blood vessels or the nasal mucosa. This is a particular issue when drugs such as beta-blockers are prescribed (Marsden, 2007). For example, the beta-blocker timolol can cause bronchoconstriction, hypotension, bradycardia, nausea, diarrhoea, anxiety, depression, hallucinations and fatigue. These effects can be reduced through the use of punctual occlusion (keeping the eye closed for a slow count of 60) after administration. Alternatively, the patient can apply digital pressure to the tear drainage system at the nasal corner of the closed eyelids (Fig 2). These techniques minimise the amount of drug being taken into the nasolacrimal system and into the systemic circulation. In a theatre setting or when the eye is thought to have been lacerated or penetrated, preservative-free eye drops must be used to stop potentially sight-threatening complications. The preservative will cause intraocular irritation and inflammation. Eye ointment, if prescribed for the eye itself, should be applied into the lower fornix in a strip of approximately 5mm. If prescribed for treating the eyelids, care should be taken to ensure the ointment is not be placed in the eye itself. Eye drop dispensing aidsEye drop dispensing aids (Fig 3) can help patients to self-medicate and become independent in managing their own condition, particularly when it is long term, such as open-angle glaucoma. The dispensing aid must match the patient’s needs and must also fit the eye drop bottle. When patients are prescribed several different eye drops, they will need an aid for each bottle. Eye drop aids are available on prescription but some pharmaceutical companies provide them free of charge for their products. The International Glaucoma Association has developed a compliance briefcase that contains samples of most types of eye drop aids and provides these free of charge to eye units in the UK. Generic eye dropsMany eye drops are now off licence and a generic product may be prescribed. Generic preparations are generally cheaper than proprietary products; they usually contain the same ingredients but not necessarily in the same quantities. This may cause sensitivity, resulting in sore eyes. If this occurs, the proprietary item may be dispensed. It should be noted that generic bottles are not a uniform size and, as a result, the drop size itself may be larger. This can result in the drug not lasting as long as the proprietary brand. Safety considerationsAfter administration of eye drops or ointments, patients must be advised against driving or operating machinery until their vision has cleared and/or their eyes have stopped stinging. Correct medication storage is essential. Some eye drops, such as chloramphenicol, must be stored in a refrigerator before and after opening while others are stored in the refrigerator after opening only - it is important to read the instructions carefully. In hospital settings, eye drops should be discarded after seven days and replaced if the treatment continues. In non-hospital settings, drop bottles should be replaced every 28 days (Andrews, 2006). DocumentationThe drugs administered should be documented accurately in patients’ notes in accordance with local and national guidance, and nurses should also evaluate the effect of treatment (RCN, 2013; NMC, 2010). ConclusionNurses, patients and carers must have an up-to-date knowledge and understanding of the therapeutic effects and potential side-effects of the topical drugs they are using for eye conditions. They should also ensure the drugs are used at the correct time and in the correct order (Table 1), with an appropriate time lapse (ideally five minutes) between drugs when more than one is prescribed. One drop of each drug is sufficient and action should be taken to ensure the risk of adverse systemic absorption is minimised. Drop-dispensing aids can be used to enable patients to become self-sufficient with eye drop administration. Key points
