Patients who correctly administered their eye-drops before and after counseling.
Correctly performed eye-drop administration at baseline of all patients (black), intervention group (grey), and control group (white) who regularly used eye-drops (A). Correctly performed eye-drop administration after counseling of all patients (black), intervention group (grey), and control group (white) who regularly administer eye-drops (B). Seven patients in the intervention group and one patient in the control group correctly administered eye-drops at baseline and, thus, received no counseling (C). Correctly performed eye-drop administration after counseling of all patients (black), intervention group (grey), and control group (white) using eye-drops for the first time (bottom). The eye-drop administration process comprised six steps: 1 = hand washing, 2 = instilling a single drop, 3 = instillation into the conjunctival sac, 4 = eyelid closure for approximately one minute, 5 = concomitant nasolacrimal occlusion, and 6 = dropper tip was not touched. *significant compared to baseline (p ≤ 0.001).

Number of patients who correctly administered eye-drops prior to counseling at baseline, 1-month follow-up, and 6-month follow-up in relation to the total number of patients (black), all patients in the intervention group (grey), or in the control group (white) who were assessed for eye-drop administration errors. *significant compared to baseline (p ≤ 0.001).
