Description Objective: The purpose of this retrospective study was to evaluate an incidence of complications after deep nonpenetrating sclerectomy (DS) with different type of implant. Methods: A total of consecutive 92 eyes (76 patients) were divided into 3 groups. The first group underwent DS without implant (34 eyes, 29 patients), the seccond group underwet DS with absorbable collagen implant Staar© (31 eyes, 25 patients) and the third group underwent DS with non-absorbable implant T-Flux© (27 eyes, 22 patients). The complications were divided into 3 types – peroperative, early postoperative and late postoperative. Results: The incidence of complications in above mentioned 3 groups was as follows: Peroperative complications: Perforation of trabeculo-Descemets membrane (2,6; 4,2; 3,7% respectively). Early postoperative complications: Filtrating operating wound (no occurrence in our groups), Choroideal detachment (17; 19;16% resp.), Hypotony (10; 8; 5% resp.), Hyphaema (7; 3; 0% resp.), Infectious complications (no incidence of blebitis or endophthlamitis in our groups), Flat anterior chamber ( 7; 5,7; 5,5% resp.), Dislocation of implant (1 case of dislocation of Staar©, 1 case of dislocation of T-Flux©). Late postoperative complications: Fibrosis of filtering bleb (30; 36; 24% resp.), Encapsulated filtering bleb (no incidence in our groups), Peripheral anterior synechiae (0; 4,2; 3,7% resp.), Cataract progression (total incidence 5,5%). Conclusions: Based on our results we suggest that DS allows effective lowering of intraocular pressure, without necessity of opening anterior chamber. It brings lower incidence of complications compared to classical penetrating trabeculectomy. Use of implant increases success of DS due to intrascleral fibrosis reduction. We documented better effect of non-absorbable implant T-Flux© compared to absorbable collagen implant Staar©. The highest incidence of intrascleral fibrosis was in group of DS without implant.
