PURPOSE: To determine the efficacy and the rate of complications of this procedure. METHODS: In a prospective study we selected 11 patients with uncontrolled glaucoma, with open angle glaucoma. The success rate was decrease of the intraocular pressure by 30% of the pre-surgical pressure. RESULTS: The pressure dropped from 24±7 to 12.6±3.7, and we decreased the number of eye drops from 2.2±1.0 to 0.5±0.5 (p<0.005). DISCUSSION: Needling can be an alternative for glaucoma surgery failure, but the success rate of this procedure should improve in the long-term. The Simmons revision showed a significant change of pressure that was sustained for the period of this study. 64% of the patients reached pressure below 14 mmHg. CONCLUSION: The Simmons revision is safe and effective to recover non-functional blebs.
