AIM: To compare the long-term outcomes of the Ex-PRESS miniature glaucoma device implanted under a scleral flap in combination of phacoemulsification with intraocular lens implantation in primary open angle glaucoma (POAG) and chronic primary angle-closure glaucoma (CPACG).
METHODS: Retrospective, comparative study. A total of 60 eyes (60 patients) receiving the Ex-PRESS miniature glaucoma device implantation combined with phacoemulsification were reviewed. Thirty eyes (30 patients) had the combined procedures for POAG, and the other 30 eyes (30 patients) for CPACG.
RESULTS: The follow-up was 39.37±7.09mo (range 3 to 49mo) in patients with POAG and 37.10±9.26mo (range 9 to 49mo) in patients with CPACG (P=0.29). The mean change in best corrected visual acuity was 0.41 logMAR for POAG and 0.38 logMAR for CPACG at the last follow-up (P=0.22). The postoperative intraocular pressure (IOP) of the POAG group was significantly lower than the CPACG group at 1, 3, 12, and 18mo after surgery (P=0.02, 0.00, 0.04, 0.01) with similar glaucoma medications after surgery (P>0.16). At 3y after surgery, the cumulative complete and qualified success rates were 63.3% (POAG) and 53.3% (CPACG), 83.3% (POAG) and 73.3% (CPACG) (P=0.41, 0.49), respectively. The POAG group had more hypotony than the CPACG group (P=0.04).
CONCLUSION: The long-term outcomes show the Ex-PRESS implantation combined with phacoemulcification can effectively lower the IOP in both the POAG and CPACG groups. The POAG group seems to have lower postoperative IOP and a higher risk of hypotony.
