This is a prospective, observational, consecutive, qualitative, multicenter study. Based on the available published evidence that supports patient challenges with eyedrop administration, the purpose of this video-capture study is to evaluate a more real-world population of consenting patients, regardless of age, with or without visual impairment, at routine eyecare visits.

To date, no studies have been performed evaluating a real-world population consisting of daily routine eyecare clinic patients with or without visual impairment. This study will help to determine the ability to achieve success with self-administration of eyedrops in the real world.

Introduction: This is a prospective, observational, consecutive, qualitative, multicenter study. A robust body of evidence suggests patients demonstrate challenges with eyedrop adherence and improper administration. The current standard of care following ophthalmic surgery is topical treatment with corticosteroids, antibiotics, and NSAIDs. Prospectively evaluated patients accuracy in administering eyedrops, during the post-operative period of cataract surgery, with 92.6% of patients demonstrating at least one type of improper administration technique. Few examples of possible errors included neglect of handwashing, failure to shake the eyedrop bottle, contamination of the bottle tip, incorrect amount of drops, and even missing the ocular surface entirely. Additionally, there was an incongruence between patient's impression of their technique and physician's observation. Thirty-five percent of patients who reported not missing the eye, did miss the eye under observation, and 39.3% of the patients who believed they never touched the eye with the bottle tip, did touch the ocular surface.

Similar studies were also performed in visually impaired patients due to glaucoma and retinal diseases with up to 47% of patients with retinal diseases touching the bottle to the eye, and up to 30% of patients not being able to administer a drop into the eye.

The objective of this study is to assess the accuracy of successful eye drop administration in patients undergoing routine exams.

This study also seeks to understand the discrepancy between patient impressions of eyedrop instillation success compared to success determined by ophthalmologist and optometrist evaluation.

Study Design This study will video capture adult subjects or Legal Authorized Representative (LAR) for minor subject's administration of one artificial tear onto the ocular surface. A temporal view video recording will be obtained. Subjects age 11 or older will self-administer the eye drops. Subjects age 10 or younger will have eye drops administer by the subject's LAR. Adult subjects or LAR will administer the drop with their dominant hand in the eye of the subject's preference.

Subjects age 11 or older shall be in a seated position while the eye drops are self-administered. Subjects age 10 or younger can either be seated or laid based on the LAR's preference.

There will be a total of three eye drop administration attempts - two attempts on the first visit (Day 0) and one attempt at second visit (Day 30 +/- 7 days). The first eye drop administration attempt will be without coaching. The subject will then receive eye drop administration technique improvement coaching by study staff and a second eye drop administration with video recording will be obtained. One month later, the subject will return at visit 2 for a third attempt for eye drop administration without any additional coaching (to observe the retention of previous eye-drop administration technique coaching) and a video recording will be obtained.

All video recordings will then be retrospectively evaluated by independent ophthalmologist and optometrist graders according to pre-specified success and failure criteria.

Inclusion Criteria:

• Patients or parents of minor patients who consent to participating in the study

Exclusion Criteria:

• Any patient who does not consent to study participation

Consented, routine, and real world eyecare clinic patient population, regardless of age, with or without visual impairment, willing to administer an artificial tear with video capture.
