Our goal is to develop an eye drop device that can deliver a single drop of medication while also preventing the flow of excess medication (streaming). Furthermore, this device should assist the user in placing the eye drop into the eye and accommodate the array of differently sized bottles that are used in eye drop medications. The device should also facilitate the squeezing of the bottle. We hope to reduce the cost of eye drop medication by administering a minimal amount with a high success rate of getting the eye drop into the eye.
We have successfully created a prototype of our design. It is described in a detailed report, as found below ("Final Report"). We also presented this prototype at the poster presentation on April 30th. Our slides are also available below. Our prototype, along with a dimensioned CAD image, is presented here:
