All postoperative IOP was significantly lower compared with preoperative IOP (P = 0.001). There was a significant decrease in the number of medications required after surgery. The baseline mean number of medications was 3.4± 0.02 (range from 1 to 4), while postoperatively the mean number of medications decreased to 0.7± 0.01 at 12 months (P < 0.01). The qualified success rate was 6/22 eyes, and the complete success rate was 16/22 (72.7%) at 12 months, respectively.Conclusion: The combined phacoemulsification and Ex-PRESS shunt implantation with automated peripheral iridectomy is an effective and safe procedure to treat chronic angle closure glaucoma.Keywords: Ex-PRESS shunt, chronic angle closure glaucoma, iridectomy
