| 目的观察改良大孔径圆形 Nd:YAG激光后囊膜切开术治疗后发性白内障的疗效和安全性。方法选取 2017年 11月至 2018年 8月铜陵市人民医院就诊的后发性白内障病人 36例 39眼，行改良大孔径圆形 Nd:YAG激光后囊膜环形切开(直径为 5.0～6.0 mm)，能量设置单脉冲 2 mJ，有效激光点数 10～30点，然后切开后囊膜与玻璃体的牵拉，促进圆形后囊膜碎片与玻璃体完全分离，并下沉入玻璃体腔，术毕双氯芬酸钠滴眼液滴眼 3d。检查并比较术前、术后 3d、术后 1月的视力、眼压、前房深度和黄斑体积(直径 3 mm圆区)。结果所有病人中，无一例出现人工晶体偏位。术前、术后 3d、术后 1月，眼压、前房深度、黄斑体积分别为( 14.7±2.8)mmHg，(4.40±0.38)mm，(2.250±0.152)mm3；(15.2±2.6)mmHg，(4.38±0.43)mm，(2.254±0.154)mm3； |

| Objective To observe the efficacy and safety of modified large circular pattern Nd:YAG laser posterior capsulotomy. Methods 36 cases(39 eyes)with posterior capsular opacification were selected in our hospital from November 2017 to August2018 in this prospective study.The laser posterior capsulotomy of all cases were conducted along a modified large circular pattern(diameter of 5.0?6.0 mm).The energy was set by 2mJ/pulse with efficient laser points from 10 to 30.Vitreous stands attached withfragment were cut off by the laser after circular application.The circular fragment was completely separated from vitreous，and then this fragment was quickly sunk in intravitreal space.Diclofenac sodium eye drops were used four times a day for 3 days，postopera? tively.The best corrected visual acuity，intraocular pressure，anterior chamber depth，and macular volume(diameter of 3mm)were measured and compared preoperatively，3 days and 1 month postoperatively.Results There were no intraocular lens deviation in all patients.The intraocular pressure，anterior chamber depth and macular volume were(14.7±2.8)mmHg，(4.40±0.38)mm，(2.250±0.152)mm3；(15.2±2.6)mmHg，(4.38±0.43)mm，(2.254±0.154)mm3；(15.0±2.5)mmHg，(4.36±0.37)mm，(2.249±0.154)mm3，re? spectively before and 3 days，1 month after surgery.The differences were not statistically significant(P＝0.262，0.496，0.337).The best corrected visual acuity(logMAR)was(0.56±0.28)(0.11±0.33)，(0.08±0.70)，with statistically significant(P＝0.000)dif? ference，respectively before and 3 days， ry.Conclusion The modified large circular pattern Nd:YAG laser pos? terior capsulotomy is an effective and safe method for the treatment of posterior capsular opacification，which improves vision obvi? ously with no side?effect on the anterior chamber depth，intraocular pressure and macular volume. |
