PURPOSE: To describe a new, highly accurate, tactile technique to increase accuracy in the self-administration of eye drops. DESIGN: Interventional case series. METHODS: Ten adult patients with loss of fixation (< or = 20/400) in one eye and ten adult patients with loss of fixation in both eyes instilled one drop of artificial tears in each eye using the technique normally employed at home. The time required to instill each drop, the number of drops squeezed from the bottle, and location of the drops' landing points on the face or eye were recorded. The patients were then instructed in a new technique for instillation, guided through the procedure once, and allowed to practice until comfortable with it. All measurements were then repeated. RESULTS: In patients with loss of fixation in one eye, an additional 3.2 +/- 4.1 seconds were required to instill a drop using the new technique (P <.0001, paired t test; range, -7-18 seconds). The mean number of drops dispensed decreased by 0.1 +/- 0.6 drops (P =.60, paired t test; range, -2-1 drop). The accuracy of drop placement increased from 80.0% to 82.5% (P =.32, paired t test). In subjects with loss of fixation in both eyes, using the new technique increased the time needed to instill a drop by 3.8 +/- 3.8 seconds (P <.0001, paired t test; range, -3-13 seconds). The average number of drops dispensed decreased by 0.1 +/- 0.6 drops (P =.25, paired t test; range, -2-1 drop). The accuracy of placement increased from 63.0% to 85.0% (P =.001, paired t test). CONCLUSIONS: This technique of drop instillation may be beneficial for patients with significant visual impairment in both eyes.
