Plain English summary of protocol

Background and study aims
Eye drops are commonly used in the treatment of eye conditions. They are used for the prevention or treatment of infective or inflammatory disorders, to prevent and decrease the complaints of dry eye, and for eye examinations.
Failure to properly administrate eye drops can prolong the condition, clinical outcomes can be negatively affected and may present a risk to the patients’ vision.
The aim of this study is to investigate whether instillation of cyclopentolate eye drops to the corner of the eye and immediately opening the eyelid or opening of the lids in few seconds after instillation would make any difference on dilating the pupil and feeling of irritation while also comparing the traditional method with these two methods.

Who can participate?
Patients who require eye drops for eye examination

What does the study involve?
Participants were split into two groups. In both groups, one drop was administered in the traditional method into the right eye; in the left eye, the drop was instilled while the lids were closed. In the first group, the patient was asked to open his or her eye immediately, in the second group the patient was asked to open his or her eye after 10 seconds. The diameters of both pupils were measured before and after 40 minutes after the instillation of the eye drop. After the instillation, the feeling of irritation was evaluated with a visual analogue scale (VAS).

What are the possible benefits and risks of participating?
Patients might benefit from a more comfortable eye drop instillation experience, while the risk is the need for second eye drop instillation in the case the investigated method fails.

Where is the study run from?
University of Kocaeli (Turkey)

When is the study starting and how long is it expected to run for?
November 2017 to January 2019

InterventionParticipants were randomly allocated to one of two groups. Participant patients arrive in a random time sequence (Patients arrive for periodic eye examination and asked to join the study prior to the examination and if volunteered patient consents are taken. Patients are not aware of which group they are participating in). The first patient was registered to group 1 and second to group 2 third to group 1 and so on until registrations are closed.

One drop of cyclopentolate was administered in the traditional method with the patient’s head tilted back, the lower eyelid held and drop instilled into the inferior fornix in right eye. In the left eye the drop was instilled to the inner canthus while the lids were closed.

In the first group the patient was asked to open his or her eye immediately, in the second group the patient asked to open his or her eye after 10 seconds.
Intervention typeBehavioural
Primary outcome measurePupil size was measured under constant illumination with the Plusoptix A09 autorefractometer. The diameters of both pupils were measured before and after 40 minutes after the instillation of the eye drop. All drops were instilled by the same investigator while all pupil measurements were made by an ophthalmic specialist technician unaware of the study.
Secondary outcome measuresFeeling of irritation was evaluated with visual analogue scale (VAS), patients were asked how much irritation felt according to the scale 40 minutes after eye drop instillation
