Objectives

Narrative objectives1

The objective of this study is to evaluate the accuracy of an eye-drop bottle sensor in detecting eye-drop instillation behavior by determining whether eye drops actually enter the eye when the sensor classifies the action as eye-drop instillation behavior.

Basic objectives2

Others

Basic objectives -Others

Observational study or interventional study: to be confirmed. Because 0.2% fluorescein ophthalmic solution is administered for research purposes, registration as an interventional study may be more appropriate.

Assessment

Primary outcomes

The proportion of participants in whom the eye drop is judged to have actually entered the eye, based on contact lens staining after administration of 0.2% fluorescein ophthalmic solution, among those classified by the eye-drop bottle sensor and deep learning algorithm as having performed eye-drop instillation behavior.

Interventions/Control_1

Participants will wear a non-powered protective contact lens before eye-drop instillation. A magnified image of the eye will be obtained using a slit-lamp microscope before instillation. Participants will then instill 0.2% fluorescein ophthalmic solution using an eye-drop bottle equipped with an eye-drop bottle sensor. After instillation, another magnified image of the eye will be obtained using a slit-lamp microscope. If the contact lens is stained, the eye drop will be judged to have entered the eye. If the contact lens is not stained, the eye drop will be judged not to have entered the eye. After assessment, the contact lens will be removed. Data recorded by the eye-drop bottle sensor will be classified by deep learning as either eye-drop instillation behavior present or eye-drop instillation behavior absent.
