The SITE Study - Dexamethasone Ophthalmic Insert In OR on Day of Surgery Versus In-office Post-Op Day 1

Study Overview
=================
Brief Summary
-----------------
To assess the safety and effectiveness of treatment with an intracanalicular dexamethasone (0.4mg) insert in the operating room following cataract surgery/intraocular lens implant (IOL) compared to insertion 1-day post-op.

Detailed Description
-----------------
This is a randomized, controlled study to evaluate the safety and effectiveness of treatment with an intracanalicular dexamethasone (0.4mg) insert in the operating room following cataract surgery/intraocular lens implant (IOL) compared to insertion 1-day post-op. There will be approximately 50 eyes with two groups: Group 1 (up to 10 eyes) will receive the insert in the lower punctum on the day of surgery in the OR. Group 2 (up to 40 eyes) will receive the insert in the lower punctum on the day after surgery in the HOPD. Each subject's participation is expected to last for approximately 1 month and will be required to complete five scheduled visits over the course of the study period: Baseline (Screening Visit), Operative Visit/Insertion Day (Day 0), Day 1, Day 7 and Day 30.
