撕后囊联合人工晶状体光学部后囊夹持治疗儿童白内障

目的评价连续环形撕后囊联合人工晶状体光学部后囊夹持术治疗儿童白内障的临床疗效。方法对51例（83只眼）因儿童先天性白内障行连续环形撕后囊联合人工晶状体光学部后囊夹持术的患儿进行回顾性分析,记录术前及术后的裸眼视力、最佳矫正视力、屈光度数和眼压。观察手术并发症和术后眼部情况,随访时间为6～36个月。结果术中共75只眼人工晶状体光学部后囊夹持成功,手术成功率占90．4％;术后最佳矫正视力≥0．5,占48．0％（36／75）,夹持成功患儿随访期间均未出现视轴区混浊;主要并发症包括前房渗出物、虹膜后粘连、人工晶状体表面沉积物。结论连续环形撕后囊联合人工晶状体光学部后囊夹持术是治疗儿童白内障安全、有效的办法,尤其有效预防了后发性白内障的发生。（手华眼群杂志,2006,42：400-402）

Posterior continuous curvilinear capsulorhexis with optic capture of the posterior chamber intraocular lens in pediatric cataract

Objective To assess the clinical effects of posterior continuous curvilinear capsulorhexis with optic capture of the posterior chamber intraocular lens in pediatric cataract. Methods Fifty-one cases (83 eyes) received posterior continuous curvilinear capsulorhexis with optic capture of the posterior chamber intraocular lens. Preoperative and postoperative visual acuity and refractive error were recorded. Intraoperative and postoperative complications were observed. The follow-up period was from 6 to 36 months. Results Implantation of optic capture of the posterior chamber intraocular lens was successfully performed in 75 eyes (90.4%). The mean postoperative best corrected distant visual acuity achieved 0.5 or better in 75 eyes (48.0%). No eyes with optic capture were found optic axis opaque. The major complications of optic capture were anterior chamber fibrous exudation, iris posterior synechia and lenticular precipitates. Conclusion Optic capture of the posterior chamber intraocular lens is safe and effective in the treatment of pediatric cataract to posterior continuous curvilinear capsulorhexis especially in the prevention of secondary opacification from the visual axis.
