About

Drug delivery platforms are an innovative exciting advancement in ophthalmology. They allow patients to eliminate topical medications which are generally associated with lack of compliance, difficulty of use and requiring help from family members. These delivery systems can be applied easily in office, and patients do not have to worry about drop insertion in their post-operative regimen. The results of this research project should help to answer the following question: Does the use of a physician administered intracanalicular dexamethasone insert improve the signs and symptoms of ocular allergy and dry eye disease in KC patients compared to the use of topical loteprednol etabonate ophthalmic gel 0.38%?

18 participants in 2 patient groups

Dexamethasone insert
Experimental group
Description:
Per participant, one eye will be randomized to receive the intracanalicular dexamethasone insert at the baseline visit (study eye). DEXTENZA is an ophthalmic insert that is inserted in the lower lacrimal punctum into the canaliculus at the day 1 visit by pulling the lower lid taught and using a forceps to insert the medication into the lower canaliculus through the lower punctum.
Treatment:
Drug: dexamethasone ophthalmic insert 0.4 mg, for intracanalicular use
Loteprednol etabonate ophthalmic gel 0.38%
Active Comparator group
Description:
Per participant, one eye will be randomized to receive the standard of care topical lotemax etabonate ophthalmic gel 0.38% (control eye). Patients will be prescribed a loteprednol etabonate ophthalmic gel 0.38% and will instill one drop into the eye following a 4x/day,3x/day,2x/day,1/xday weekly taper
Treatment:
Drug: Loteprednol Etabonate 0.38% Ophthalmic Gel/Jelly
