1 Clinical Trials for Various Conditions
The goal of this clinical trial is to compare the onset and duration of numbness of the surface of the eye following the administration of numbing drops, called proparacaine, using either a standard eye drop bottle or a "Nanodropper" adaptor. The Nanodropper is designed to administer smaller-sized drops, or microdrops. Participants will: 1. Complete a baseline eye exam. 2. Receive a numbing drop using a standard dropper in one eye and the Nanodropper in the other eye. 3. Have their eyes tested for numbness at specific time points (30 seconds, 1, 2, 5, and 10 minutes after getting the drops). 4. Tell the researchers if they feel pain during the eye sensation tests. 5. Complete a survey about their experience with the eyedrops and testing procedure. This study could help us find a way to use less medication while still effectively administering eye medications, potentially saving money and reducing medical waste.
