To evaluate the benefit of treatment with a physician administered intracanalicular dexamethasone insert in evaporative dry eye disease (DED) patients with meibomian gland disfunction (MGD) and underlying inflammation undergoing iLUX MGD Treatment System.
This prospective study will use a fellow-eye design for 30 participants, (2 groups of 15) equating to 60 eyes. All eyes will receive bilateral iLUX MGD Treatment System. The most symptomatic eye will be selected to receive DEXTENZA® insertion on the day of the procedure (study eye). In group 1, the other eye will be assigned to receive prednisolone acetate 1% on a 4,3,2,1 month taper schedule (active comparator). In group 2, the other eye will receive punctal "sham" dilation (control eye). If there is no obvious symptomatic difference, the right eye will receive the intracanalicular insert. The study group will consist of 30 eyes receiving DEXTENZA® insertion. The control group will consist of 15 eyes receiving prednisolone acetate 1% and 15 eyes receiving sham punctum dilation. Thus, for every eye in the study group, there will be a paired eye with similar baseline characteristics in the control group sourced from the same participant. This fellow-eye design allows for greater control of potential confounders tied to participants' systemic and ocular health.

All eyes will undergo iLUX MGD Treatment System for the treatment of evaporative DED secondary to MGD. Patients will have their most symptomatic eye selected to receive the dexamethasone intracanalicular insert at the day of the iLUX MGD Treatment System (study eye). There will be 2 groups:
Group 1: fellow eye will receive topical prednisolone acetate 1% on a 4,3,2,1 taper for 30 days (control eye) Group 2: fellow eye will receive punctal "sham" dilation (control eye).
If there is no obvious symptomatic difference, the right eye will receive the intracanalicular insert.
