Single-dose device shows promise in enhancing eye drop adherence for ocular diseases

Posted on

The Dropaid Single-dose delivery aid, designed for single-dose containers, has shown significant promise in addressing the challenge of patient adherence to topical medication in chronic ocular diseases such as vernal keratoconjunctivitis (VKC), glaucoma, and ocular surface disease, according to a study.

The usability study, involving parents and caregivers of VKC patients, demonstrated that the device is easy to use, comfortable to hold, and facilitates accurate eye drop instillation.

The 30 parents and caregivers of patients with VKC included in the study were tasked with assessing the ability to squeeze a single eye drop from the single-dose container onto a pediatric medical dummy’s eye.

Most participants found the task of opening the single-dose units (SDUs), preparing, and positioning the device to be “very easy.” When it came to providing a single eye drop from the container, 87% of participants rated the delivery aid as either “very easy” or “easy.”

For general ease of use, 84% considered the delivery aid as either “very easy” or “easy.” Notably, 93% of participants rated Dropaid Single-dose as either “very comfortable” or “comfortable” to hold.
