The TRAVATAN Dosing Aid accurately records when drops are taken.
OBJECTIVE
To assess the accuracy of Travatan Dosing Aid recordings.


METHODS
Prospective evaluation of drop-recording accuracy.


METHODS
Physicians and patients used the Dosing Aid, and logs of usage were compared to the data obtained from the Dosing Aid.


RESULTS
Five physicians and 20 patients participated. Devices used by physicians recorded all drops dispensed. Extra readings were recorded when physicians carried the devices during the day. For patients, 93% of all drops were recorded, with 18 of 20 subjects having over 85% of the drops recorded. Seventy percent of patients would continue using the device.


CONCLUSIONS
The Dosing Aid accurately recorded most eyedrops administered by patients and physicians. Given recent documentation of widespread under-compliance with medical therapy, the Dosing Aid could be a useful addition to clinical practice and research.
