人工晶状体光学部囊膜后嵌顿术治疗学龄期儿童外伤性白内障术后无晶状体眼

Supracapsular implantation with optic capture of posterior chamber intraocular lens in aphakic school-age children after traumatic cataract

目的 评价人工晶状体（IOL）睫状沟植入、光学部囊膜后嵌顿治疗学龄期儿童外伤性白内障术后无晶状体眼的临床效果.方法 回顾性系列病例研究.对13例（13只眼）外伤性白内障术后无晶状体眼行IOL睫状沟植入、光学部囊膜后嵌顿术患儿的临床资料进行回顾性分析,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6～42个月.结果 IOL睫状沟植入、光学部囊膜后嵌顿术中共13只眼囊膜后嵌顿成功;术后最佳矫正视力0.2～1.0,嵌顿成功患儿随访期间均未出现视轴区混浊,IOL位置稳定;主要并发症包括前房渗出物、虹膜后粘连、IOL表面沉积物,仅1例患儿出现IOL襻异位.结论 IOL睫状沟植入、囊膜后嵌顿治疗学龄期儿童外伤性白内障术后无晶状体眼安全有效.

Objective To assess the clinical effects of supracapsular implantation with optic capture of the posterior chamber intraocular lens in school-age children with traumatic cataract. Method It was a retrospective case series study. Thirteen cases （ 13 eyes） received posterior curvilinear capsulorhexis with optic capture of the posterior chamber intraocular lens. Pre- and post-operative visual acuities were recorded.Intra-o and post-operative complications were observed. The follow-up period ranged from 6 to 42 months.Results Implantation of optic capture of the posterior chamber intraocular lens was successfully performed in 13 eyes. The best-corrected-visual acuity ranged from 0.2 to 1.0. No optic axis opaque was found in 10 eyes with optic capture. The major complications of optic capture were lenticular precipitates and posterior synechia of the iris. Intraocular dislocation was found in one case two weeks after the operation.Conclusions Supracapsular implantation with optic capture of the posterior chamber intraocular lens is safe and effective for the treatment of traumatic cataract in school-age children.
