Abstract Details


To assess the technique of eye drops instillation in health professionals.


Department of Ophthalmology, General Hospital of Veria, Veria, Greece.


63 health professionals (doctors and nurses, male / female: 26/31) of mean age 38.9 years participated in the study. All instilled eye drops by themselves because of dry eyes or ocular inflammation (conjunctivitis or keratitis at some point in the past). The evaluation was conducted by a questionnaire completed by patients.


99% of the patients believed that instilled the eye drops correctly and 3% said they rarely missed one dose. Only 27% washed their hands before instillation. 74% instilled the drops in sitting position. 78% were pulling the lower eyelid, while 69% reported contact of the vial tip with the periocular tissues. 86% closed their eyes after instillation, 2% occluded the canaliculus, 83% cleaned the excess of drops, 36% left an interval between the instillations. 67% felt the drops in the mouth and 14% reported discomfort. Concerning the storage of the vials, 85% of the respondents used a cool / dark place and 41% the refrigerator. None of them allowed anyone else to use the drops. 66% checked the expiry date, 27% wrote down the opening date on the label, 73% threw the bottle four weeks from opening. 13% of patients kept a spare vial, 11% had it with them, 93% kept it away from children.


The level of knowledge of health professionals about the eye drops instillation is not satisfactory. Their knowledge regarding the hand hygiene before the instillation, the significance of avoidance of the bottle tip contact with the eye or periocular tissues during the instillation as well as the the nasolacrimal occlusion after the instillation is found to be insufficient. As inadequate installation technique is a cause of unsuccessful treatment in glaucomatous patients, the level of knowledge for the instillation of drops among health professionals is important to be improved.
