BACKGROUND: Beside the established methods in glaucoma surgery, several procedures have been developed in the recent past including viscocanalostomy as a non-penetrating surgery. The efficiency of a combination of this procedure with an intrascleral implant and/or with cataract surgery was examined in this retrospective study over a period to 60 months postoperatively. PATIENTS AND METHODS: 67 eyes from 49 patients with glaucoma were operated in two different operational groups. 39 eyes had a viscocanalostomy (Group "V"). 16 eyes in this group additionally got a T-Flux implant ("ViskoT"), 23 did not ("Visko"). A combined cataract extraction and viscocanalostomy was undertaken in 28 eyes (Group "VK"), 18 of which did not ("ViskoKa"), and 10 of which did receive a T-flux implant ("ViskoKaT"). RESULTS: The mean preoperative intraocular pressure was 27.1 ± 4.5 mmHg and went down to 17.4 ± 2.9 mmHg postoperative up to the point of 60 months: there was a significant difference in the overall postoperative intraocular pressure in comparison to the preoperative intraocular pressure. There was, however, no significant effect to be found until after 5 years on the postoperative intraocular pressure by cataract extractions and also not by the implantation of a T-Flux. However, significantly less medication was applied up to the postoperative point of 12 and 36 months in the group with cataract surgery (VK). This difference was lost in the course of time and was no longer detectable after 60 months. However, an overall rise in both medication and goniopuncture (31.3 %) of the Descemet using YAG laser was necessary in the course of time, in order to keep a constant level of the postoperative intraocular pressure. CONCLUSIONS: Viscocanalostomy represents a safe surgical antiglaucomatous method for improving the intraocular pressure. A respective clinical improvement could be observed during the follow-up period of up to 60 months. The prognosis of intraocular pressure does not improve by the use of intrascleral implants and viscocanalostomy with simultaneous cataract surgery, however.
