AIM: To observe the effectiveness of gonioscopy-assisted mechanical goniosynechialysis combined with phacoemulsification and intraocular lens implantation in treatment of primary angle-closure glaucoma(PACG)with cataract.

METHODS: Gonioscopy-assisted mechanical goniosynechialysis combined with phacoemulsification was performed in 52 eyes of 45 patients with PACG and cataract. The synechial angle closure is ≥180° by dynamic observation with gonioscop. All Patients received gonioscopy-assistance mechanical goniosynechialysis combined with phacoemulsification and intraocular lens implantation. The follow-up time after surgery was 6mo. Observe and record the best corrected visual acuity, intraocular pressure(IOP), range of angle-closure and complications 1mo, 2mo, 3mo, and 6mo after surgery.

RESULTS: Preoperative mean IOP was 33.92±5.45mmHg and was 15.40±2.67, 15.65±2.65, 15.57±2.50, and 16.17±2.65mmHg, 1mo, 2mo, 3mo, and 6mo after surgery, respectively. All of the postoperative decrease in IOP were significant(P<0.01).

CONCLUSION: Gonioscopy-assisted mechanical goniosynechialysis combined with phacoemulsification is safe and effective for PACG with cataract.
