目的：探讨超声乳化人工晶状体(IOL)植入联合房角分离术治疗原发性慢性闭角型青光眼的有效性。

方法：纳入2018-05/11于西安市第一医院眼科住院的原发性慢性闭角型青光眼合并白内障患者共33例35眼，对术前和术后6mo的最佳矫正视力、眼压、中央前房深度、房角开放距离₅₀₀、小梁虹膜夹角、房角关闭或粘连的范围进行比较。

结果：患者34眼(97%)术后最佳矫正视力较术前提高； 27眼(77%)术后不需给予任何降眼压药物，眼压维持在21mmHg以下； 术前前房深度、房角开放距离₅₀₀、小梁虹膜夹角平均值分别为2.04±0.31mm、0.132±0.033μm、15.44°±3.10°，显著小于术后的平均值(3.26±0.29mm、0.407±0.038μm、34.26°±3.60°，均P<0.01)； 术后房角关闭或粘连范围较术前减少(P<0.05)。

结论：超声乳化人工晶状体植入联合房角分离术是治疗原发性慢性闭角型青光眼的有效方式。

METHODS: Thirty-three patients(35 eyes)with primary chronic angle-closure glaucoma and cataract were enrolled in the Department of Ophthalmology, Xi'an First Hospital from May 2018 to November 2018. The best corrected visual acuity, intraocular pressure, central anterior chamber depth, angle-opening distance at 500μm from the scleral spur, trabecular iris angle, angle closure or adhesion were compared between preoperative and postoperative 6mo.

RESULTS: The best corrected visual acuity of 34 eyes(97%)was improved after operation. 27 eyes(77%)did not need any intraocular pressure lowering drugs after operation, and the intraocular pressure was kept below 21mmHg. The average value of anterior chamber depth, angle-opening distance at 500μm from the scleral spur and trabecular iris angle(2.04±0.31mm, 0.132±0.033μm, 15.44°±3.10°)before operation were significantly lower than the postoperative mean values(3.26±0.29mm, 0.407±0.038μm, 34.26°±3.60°). The range of angle closure or adhesion decreased after operation, and the difference was statistically significant.

CONCLUSION: Phacoemulsification with intraocular lens implantation and goniosynechialysis is an effective way to treat primary chronic angle-closure glaucoma.
