| Abstract: | The problem of surgical treatment of refractory glaucoma (RG) in patients with corneal disease is studied. Glaucoma prior to penetrating keratoplasty is a significant risk factor for postkeratoplastic glaucoma that results in graft failure. The main tendency of RG surgery is implantation of draining devices. The aim of our study was to evaluate the efficacy of glaucoma surgery with collagen implant in patients with RG associated with severe corneal disease. 42 operations were analyzed. This operation technique let us achieve persistent hipotensive effect and corneal improvement. The insertion of collagen implant is absolutely safe in terms of corneal graft survival and it prevents scaring in surgery zone. |
