PURPOSE: To compare and analyze the performance of a device dropper (DD) over conventional drop instillation (CDI) method on ease of administration, compliance, patient satisfaction, and intraocular pressure (IOP) control in persons with glaucoma on ocular hypotensive medications. METHODS: We enrolled 72 individuals with primary open-angle glaucoma or ocular hypertension, on treatment with fixed combination (α agonist+β blocker) drugs for at least 6 months. These were randomized into two groups (36 in each arm). Group 1 administered the drug with a DD and Group 2 used CDI method. Recruited individuals were interviewed for subjective difficulties using a formatted questionnaire at first month follow-up and IOP change from baseline was evaluated. RESULTS: Baseline demographic and ocular characteristics were similar in both groups. 57.1% in the conventional instillation and none in the DD had reported difficulty in using the eye drops on follow-up visit. DD group had significantly less spillage and contamination of eye surface or dropper tips, required minimal assistance, accurately targeted on first drop placement directly into the eye compared to CDI group (-value<0.001). Mean IOP was comparable between the two groups. CONCLUSION: DD instillation method was observed to be easier to administer, more accurate in targeting the conjunctival cul-de-sac, reduced wastage with lesser contamination compared to the CDI technique. DDs may be expected to have better compliance and effectiveness in medical management of glaucoma.
