Background  We aimed to evaluate the efficacy and safety of phacoemulsification with intravitreal 3 mg triamcinolone acetonide injection in preventing postoperative inflammation and complications in patients with non-infectious anterior uveitis and panuveitis complicated cataract.    Method  In this retrospective cohort study, 140 uveitic cataract patients who received phacoemulsification and intraocular lens implantation in Shanxi Eye hospital from January 2018 to January 2020 were reviewed. The IVTA group (51 eyes of 41 patients) received intravitreal injection of 3 mg triamcinolone acetonide (TA) at the end of surgery, and the control group (51 eyes of 41 patients) without injection matched by propensity score matching were enrolled. Outcome measures were best corrected visual acuity (BCVA), anterior chamber inflammation, intraocular pressure, corneal endothelial cell density, central macular thickness and complications within 3 months follow-up.    Results  The degree of postoperative anterior chamber inflammation in the IVTA group was lighter than that in the control group ( P  < 0.05). The postoperative logMAR BCVA of anterior uveitis was better and improved more quickly in the IVTA group( P  < 0.05). Postoperative time of using corticosteroids was shorter in the IVTA group as compared to the control group ( P  < 0.05). The central macular thickness at postoperative month 1 was statistically significantly lower in the IVTA group ( P  < 0.05). There were no statistically significant differences between the two groups in postoperative corneal endothelial cell density and intraocular pressure ( P  > 0.05). Two of 51 eyes (3.9%) in the IVTA group and 8 of 51 eyes (15.7%) in the control group had recurrence of uveitis; 6 of 45 eyes (13.3%) in the control group developed cystoid macular edema but none in the IVTA group; 11 of 51 eyes (21.6%) in the IVTA group and 22 of 51 eyes (43.1%) in the control group developed posterior synechiae postoperatively.    Conclusions  Intraoperative Intravitreal injection of 3 mg TA is an effective and safe adjunctive therapy for preventing postoperative inflammation and complications to promote early recovery for anterior uveitis or panuveitis complicated cataract patients following phacoemulsification.    Trial registration  This retrospective cohort study was in accordance with the tenets of the Helsinki Declaration and was approved by the Shanxi Eye Hospital Ethics Committee. Written informed consent was obtained from all participants for their clinical records to be used in this study.
