Purpose: To investigate the benefit of preoperative treatment with either topical nonsteroidal antiinflammatory drug (NSAID) or steroid in terms of clinical outcomes following trabeculectomy. Design: Prospective, randomized placebo-controlled trial. Participants: Sixty-one patients. Methods: Between July 2005 and October 2007, 61 consecutive medically uncontrolled glaucoma patients scheduled for first-time trabeculectomy were randomized to 1 of 3 study topical medication groups: nonsteroidal anti-inflammatory drugs (ketorolac), steroids (fluorometholone), or placebo (artificial tears). Patients instilled 1 drop 4 times daily for 1 month before the procedure and were examined on days 1 and 2, at weeks 1, 2, and 4, and at months 3, 6, 12, 18, and 24 after trabeculectomy. Main Outcome Measures: Incidence of postoperative surgical or medical interventions (needling, laser suture lysis, needling revision, and intraocular pressure [IOP]-lowering medication). Results: Fifty-four patients (54 eyes) were entered for analysis. The mean number of preoperative medications was 2.3(plus or minus)0.9. The mean baseline IOP was 21.0(plus or minus)6.0 mmHg. The mean postoperative target IOP was 16.5(plus or minus)1.8 mmHg. The mean follow-up was 23.6(plus or minus)4.0 months. The percentage of patients requiring needling within the first year was 41% in the placebo group, 6% in the NSAID, and 5% in the steroid group (P =0.006). The percentage of patients requiring IOP-lowering medication to reach the target IOP at 1 year was 24% in the placebo group, 18% in the NSAID group, and 0% in the steroid group (P =0.054 overall; P =0.038 for steroids vs. others). The log-rank test showed a significant (P =0.019) difference in medication-free survival curves between the different groups. More specifically, patients in the steroid group needed significantly less medication over the total follow-up (P =0.007). Conclusions: Topical ketorolac or fluorometholone for 1 month before surgery was associated with improved trabeculectomy outcomes in terms of likelihood of postoperative needling. In the steroid group, there was a significantly reduced need for additional postoperative IOP-lowering medication compared with the other groups.
