Study Summary
Prescription eye drop bottles elute drops that exceed the capacity of the human eye by five times. This study describes performing in clinic dilation using a novel solution for combating medical waste with Nanodropper, an eye drop bottle adapter that creates smaller eye drops.
Primary Outcome
Cycloplegia is the paralysis of the ciliary muscle of the eye resulting in dilatation of the pupil and paralysis of accommodation. Cycloplegia is defined as the "change score." Change scores were calculated by subtracting the spherical equivalent value after dilation from the value before dilation for each eye.
Interventions
- DEVICE Nanodropper
