Objective: To evaluate the long-term compensation and efficacy after non-penetrating deep sclerectomy using different types of implants.
Methods: Patients were divided in 3 groups: deep sclerectomy without implant (DS): 34 eyes, deep sclerectomy with Staar implant (DS+STAAR): 31 eyes, deep sclerectomy with T-flux implant (DS+T): 27 eyes. Postoperatively was evaluated: IOP, therapy and efficacy.
Results: The data are described by the relative quantity, continuous data by median, 5th and 95th percentile, always in order of groups: DS; DS+STAAR; DS+T, resp. Age at the time of surgery was 65.6 (44.9; 77.9); 64.5 (44.8; 85.0); 72.1 (51.8; 77.0) years. Follow-up period was 84 (36; 145); 96 (36; 141); 81 (36; 134) months. IOP was 26 (20; 32); 26 (20; 34); 26 (21,34) mmHg postoperatively. IOP was 14 (4; 18); 14 (4; 22); 8 (2; 16) mmHg at 1 month postoperatively. IOP was 17 (13; 23); 17 (12; 21); 14 (12; 18) mmHg at 96 months. IOP was 18 (1; 20); 18 (10; 22); 15 (13; 16) mmHg at 132 months. Completely without therapy were 0; 7.1; 42.9 % of eyes at 120 months. Complete success rate was 0; 7.1; 18.2 % at 96 months. Qualified success rate was 87.5; 89.5; 100 % at 96 months.
Conclusion: Deep sclerectomy is a good surgical technique to reduce the IOP in patients with glaucoma. Use of T-flux implant provides the best results in our groups.
