Safety and efficacy of topical vs intracanalicular corticosteroids for the prevention of postoperative inflammation after cataract surgery.

PURPOSE: To compare the safety and efficacy of topical prednisolone and intracanalicular dexamethasone ophthalmic insert for the prevention of postoperative inflammation after cataract surgery.

SETTING

Penn State College of Medicine, Hershey, Pennsylvania.

DESIGN

Retrospective consecutive case series.

METHODS

Patients scheduled for elective phacoemulsification cataract surgery with a plan to receive inflammation prophylaxis with topical prednisolone (prednisolone acetate 1 mg/1 mL) between January 2018 and November 2019 or intracanalicular dexamethasone (Dextenza, 0.4 mg) between December 2019 and March 2021 were screened. Patients were seen 1 day, 1 week, and 4 to 16 weeks postoperatively. Medical records were also reviewed for any urgent messages between visits. Primary end points were proportion of eyes with (1) breakthrough inflammation requiring escalation of anti-inflammatory therapy and (2) intraocular pressure (IOP) increase ≥10 mm Hg at 4 to 16 weeks of follow-up. Secondary end points included incidence of intraoperative complications, cystoid macular edema, and infectious sequelae.

RESULTS

358 patient charts (358 eyes) were screened. Of these, 262 eyes of 262 patients met the criteria for inclusion in the study; 131 eyes received topical drops, and 131 eyes received the intracanalicular insert. Among eyes that completed follow-up, 9 eyes (6.9%) in the drops group and 12 eyes (9.2%) in the insert group experienced breakthrough inflammation necessitating treatment ( P = .50). 2 eyes in the drops group and 1 eye in the insert group had elevated IOP.

CONCLUSIONS

Postoperative inflammation prophylaxis with the intracanalicular insert may be associated with similar rates of breakthrough inflammation and IOP elevation as topical drops.
