The goal of this report is to introduce a technique of transcorneal activation of the site of previous hypotensive surgery, its complications and long-term results. The study enrolled 100 patients aged from 39 to 84 who underwent a transcorneal activation procedure due to decompensation of intraocular pressure 2 weeks - 20 years after the previous hypotensive surgery. Group I included 40 patients after a nonpenetrating deep sclerectomy; group II consisted of 60 patients after a penetrating hypotensive surgery. There were no intraoperative complications during the transcorneal activation procedure in both groups. Postoperative complications occurred in 5% of patients in group I (two ciliochoroidal detachments) and in 8.3% of patients in group II (three hyphemas and two ciliochoroidal detachments). In both groups a statistically reliable decrease of intraocular pressure comparing to preoperative values was present during the whole period of follow-up (up to 3 years) and averaged 34.6%.
