Safety efficacy of single subconjunctival triamcinolone 5 mg depot vs topical loteprednol post cataract surgery: less drop cataract surgery

摘要

AIM: To do a randomized prospective interventional study for comparing the effects of a single subconjunctival triamcinolone acetonide(SCTA) injection to tapering topical loteprednol in patients undergoing phacoemulsification surgery under topical anesthesia. METHODS: A total of 400 patients were randomized into 2 groups;Group A(200 patients) received 5 mg SCTA at the end of surgery and topical ketorolac tromethamine(0.5%) with ofloxacin(0.3%) combination for 3 wk. Group B(200 patients) received tapering topical loteprednol etabonate(0.5%) along with ofloxacin(0.3%) and ketorolac tromethamine(0.5%) for 3 wk. Outcomes evaluated were intraocular pressure(IOP), anterior chamber cells/flare and macular oedema postoperatively at 1, 6 and 12 wk.RESULTS: Baseline parameters were almost similar in both the groups. No statistical difference was seen between the preoperative and postoperative IOP values for Group A(P=0.82) and Group B(P=0.61) and postoperative IOP values in between both groups(P=0.14) at 1 wk. Incidence of cells/flare postoperative was statistically not significant(P=0.82) in both groups at all follow up visits. Postoperative macular oedema was not observed at any follow up visit. CONCLUSION: SCTA appears to be an effective alternative to prolong postoperative topical steroid use.
