Purpose:
To evaluate dexamethasone intraocular suspension 9% (intraocular DXM) in real-world clinical use to manage inflammation associated with cataract surgery.
Setting:
Patients who underwent cataract surgery and received intraocular DXM at 22 outpatient eye surgery centers in the US.
Design:
Retrospective, observational chart review.
Methods:
Records of all patients who received intraocular DXM from March to December 2019 at participating centers were reviewed.
Main Outcome Measures:
Outcomes included anterior chamber cell (ACC) grades, anterior chamber flare (ACF) grades, and visual acuity, as well as intraocular pressure (IOP) and adverse events (AEs) at postoperative days (PODs) 1, 8, 14, 30. Descriptive statistics were generated.
Results:
The study population included 527 patients (641 eyes), with glaucoma history in 66 patients (80 eyes). Among eyes with recorded ACC grades, the percentage with grade 0 increased from 40% at POD 1 to 89.7% at POD 30, with similar results in eyes with glaucoma history. Among eyes with recorded ACF grades, the percentage with grade 0 increased from 78.4% at POD 1 to 97.1% at POD 30. At POD 30, 96.6% eyes with recorded results achieved target acuity. Mean IOP was 18.6 mmHg at POD 1 but declined to ≤15.2 mmHg thereafter. Investigators reported 22 AEs in 20 patients, all reported mild or moderate, the most common: IOP increase (7 events).
Conclusion:
Patients undergoing cataract surgery and treated with intraocular DXM showed favorable inflammatory and visual outcomes, without unanticipated safety problems, consistent with results of previous controlled clinical trials.
