Rain Eye Drops LLC announced the launch of a newly refined first-of-its-kind RainDrop Dispenser Aid created specifically for single-use preservative-free dry eye drops. The device, which is patent pending, is licensed exclusively by the US Department of Veterans Affairs (VA) and the University of California.1

According to the press release, the tool “is designed to help Americans with dry eye apply mono-dose eye drop vials more easily and accurately.” The dispenser aid is available free with any Rain purchase.1

Julie Schallhorn, MD, a VA ophthalmologist in San Francisco and creator of the device, explained that the device is intended to aid veterans who struggle using single-use vials with fumbled applications, squeezing too hard, or wasting precious drops. She noticed these common problems among her patients while instilling eye drops. “It’s difficult to see patients who are suffering and are not served by the current options. This was a major motivation for me,” she commented.

According to the press release, the dispenser is made of 1 piece of plastic and features a hammer-shaped handle that releases a precise drop of fluid with a stabilizing bar resting on the patient’s cheekbone that ensures consistent positioning.

The tool is designed to help with the application of mono-dose, dry eye eye drop vials more easily and accurately.

The development of the product was achieved through collaboration between bioengineers in the laboratory at the VA Technology Transfer Program (TTP) and researchers and clinicians.
