AIM:To discuss the clinical effect and safety of the combined surgeries of phacoemulsification and goniosynechialysis for patients with primary angle-closure glaucoma(PACG).

METHODS: Eighty-three eyes of 83 patients with PACG and cataract were ranomized into two groups. Group A: 39 patients with 39 eyes of angle-closure <180°; Group B: 44 patients with 44 eyes angle-closure ≥180°. The changes of visual acuity, anterior chamber depth(ACD), anterior chamber angle and IOP after operation were measured. The follow-up period was for 1a.

RESULTS: The visual acuity was improved significantly in both group after operation. No significantly difference in ACD, anterior chamber angle after operation in two groups(P>0.05). The IOP in group A was lower than that in group B 3mo after operation, there was statistical significance(P<0.05).

CONCLUSION:Phacoemulsification and goniosynechialysis can deepen ACD significantly. This method make the anterior chamber angle open, can reduce IOP and improve the patients' visual acuity, especially in patients with PACG. It is a safe and effective approach to patients with PACG and cataract.
