目的：观察前房角镜辅助下的机械性房角分离术联合超声乳化白内障摘除和IOL植入治疗原发性闭角型青光眼(PACG)合并白内障的疗效。

方法：选取45例52眼房角镜下粘连性房角关闭≥180°的PACG合并白内障患者，接受前房角镜辅助下的机械性房角分离术联合超声乳化白内障摘除。术后随访6mo，观察并记录患者术前和术后1、2、3、6mo的最佳矫正视力、眼压、房角粘连范围，以及术中和术后并发症。

结果：术前眼压为33.92±5.45mmHg，术后1、2、3、6mo眼压分别为15.40±2.67、15.65±2.65、15.57±2.50、16.17±2.65mmHg，术后眼压较术前均明显降低(均P<0.01)。

结论：超声乳化白内障摘除联合前房角镜辅助下房角分离术对于PACG疗效确切。

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.
