The disposable, self-adherent eye patch was designed to be translucent and have an adjustable vault to accommodate individual anatomy, as well as be easy for technicians to use.
A disposable and adjustable eye patch (MASK-it Eye Patch) is a novel alternative to traditional modalities for monocular occlusion that offers advantages for both patients and practices, said office administrator Barbara Masket.
“The disposable eye patch is hygienic, adjustable, and easy to use,” said Masket, who designed the patch. “It provides patients with a cleaner and more comfortable covering than the reusable, and dreaded ‘pirate patch’ and it saves time spent by technicians between patients and fellow eye exams.”
Masket works at Advanced Vision Care, Los Angeles, where she is involved in evaluating technicians’ skills in performing visual field testing. Her observations about the negatives of the pirate patch used for visual field testing motivated her to come up with a better solution for eye occlusion.
Finding better solution
“Typically, the pirate patch is cleaned with alcohol pads before each use, but that introduces cost, adds time to the procedure, and does not eliminate risk for infection transmission,” Masket explained.
“Moreover, eye pads or tissues are applied to the closed eye, under the pirate patch, inducing dark adaptation and compressing the globe, potentially disturbing the ocular surface,” she added.
There is a waiting period to allow the fellow eye to recover from dark adaptation and to allow the ocular surface to re¬cover and to remove any loose eyelashes.
Loosening of lashes is a common problem because many patients doing the visual field testing have glaucoma and are using prostaglandin analogue medications that promote eyelash growth. Furthermore, patients complain that the strap of the pirate patch disturbs their hair and facial make-up.
As she began to develop the concept for a new patch, it became apparent that the product would need to be translucent to prevent dark adaptation, self-adherent, have an adjustable vault to accommodate individual anatomy, and be easy for technicians to use. She envisioned that the product would be faster, cleaner, better and less costly than the traditional pirate patch.
