Clinical Trial Summary

This study aims to compare the effectiveness of Dextenza vs standard of care prednisolone taper after cataract surgery in diabetic patients with regards to controlling post-op inflammation at post-op days 7, 14, and 30.

Description:

The inflammation after cataract surgery is controlled at the investigators' institution by a taper of prednisolone acetate 1%, which consists of four drops daily for one week, followed by three drops daily for one week, then two drops daily for one week, then one drop daily for one week. Due to the frequency of drops needed after cataract surgery, compliance with the post-op regimen often wavers. This study aims to evaluate the efficacy of Dextenza, which has been shown to be better than placebo after cataract surgery (1), against prednisolone acetate taper. If shown to be as effective without compromising safety, it could be a very convenient alternative to prednisolone acetate taper. Furthermore, if Dextenza is shown to be as effective as prednisolone taper in diabetic patients, it could be logically generalized that it would be effective in patients without diabetes as well, as patients without diabetes (and with no confounding risk factors, such as a history of uveitis) are less prone to developing post-op macular edema. Risks are minimal for this FDA approved treatment and include iridocyclitis (10%); intraocular pressure increased (6%); visual acuity reduced (2%); cystoid macular edema (1%); corneal edema (1%); eye pain (1%) and conjunctival hyperemia (1%). These risks are comparable to prednisolone acetate.
