Brief Summary
This prospective study will use a self controlled design for 35 eyes. Patients scheduled to undergo routine cataract surgery in at least one of their eyes will have their pre-surgical measurements performed, IOL calculated and surgery planned. Then they will receive insertion of an intracanalicular dexamethasone insert into the inferior punctum. At 2 weeks (+/- 2 days) post-insertion, patients will return for an identical set of measurements. The IOL will be calculated and the surgery planned based on post-insert data. The insert will be removed if present (manually or via saline irrigation). This self controlled design allows for greater control of potential confounders tied to participants' systemic and ocular health.

Outcome Measures
Primary Outcomes (1)
