Purpose: To evaluate the preliminary results of the new non-absorbable implant HEMA in deep sclerectomy and combined phacoemulsification and deep sclerectomy. Methods: 21 patients (mean age 65y, 12 women, 9 men) had deep sclerectomy with HEMA implant and 29 patients (mean age 79y, 16women, 13 men) had combined phacoemulsification and deep sclerectomy with HEMA implant. Follow-up included day 1, week 1, month 1,2,3 and 6. Results: The deep sclerectomy group had preoperatively a mean intraocular pressure (IOP) of 23 (SD 6,5)mmHg with a mean number of 2,6 (SD 1,1) antihypertensive drugs. Postoperatively intraocular pressure level at 2 months was 13 (SD 4,5)mmHg with a mean number of 0.2 (SD 0,4) antihypertensive drugs. Complete success (pressure equal or under 15 without treatment) was achieved in 15 patients (71,4%). Complications included the need for injection of Mitomycine or 5-FU (7patients), hyphema (2 patients), transient Seidel (2 patients), but no case of hypotonie. The combined surgery group presented a mean preoperative IOP of 20 (SD 7,8)mmHg with a mean number of 2,1 (SD 1,0) antihypertensive drugs. At 2 months postoperatively IOP dropped to a level of 11 (SD 3,0)mmHg with a mean number of 0.1 (SD 0,3) antihypertensive drugs. Complete success was achieved in 24 patients (82,6%). Complications included the need for injection of Mitomycine (5 patients), hyphema (1 patients) and hypotonie (2 patients). Conclusion: The new non-absorbable implant HEMA for deep sclerectomy alone or combined with phacoemulsification showed satisfactory preliminary results. Medium and long term results remain crucial for comparative evaluation.
