儿童后房型人工晶状体二期植入临床分析

Clinical analysis of children secondary posterior chamber intraocular lens implantation

目的 总结后房型人工晶状体二期植入矫正儿童无晶状体眼的疗效,探讨儿童二期人工晶状体植入术。方法 对40只儿童无晶状体眼,在充分分离虹膜与后囊膜的粘连,形成开放的后房间隙后,根据后囊膜完整与否,采用不同术式植入后房型人工晶状体。结果 随访1～20mo,平均13.85mo。裸眼视力均等于或高于术前矫正视力,其中,裸眼视力高于术前矫正视力者23眼(57.5%),矫正视力高于术前矫正视力者33眼(82.5%),等于术前者7眼(17.5%)。结论 后房型人工晶状体二期植入对矫正儿童术后无晶状体眼是有效的,但术后应加强抗炎和弱视治疗。

Objective To evaluate the effects of secondary posterior chamber lens implantation for aphakia in children.Methods Forty consecutive pediatric aphakic eyes were retrospected.All eyes were secondarily implanted with posterior chamber lens using different operative techniques according to the condition of lens capsule remnante after dissecting the adhesions between the lens capsule and the iris and forming extent space in posterior chamber.Results Follow up ranged from 1 to 20 months,averaging 13.85 months postoperative naked visual acuity was equal or better than corrected visual acuity preoperatively in 23 eyes(57.5%).Postoperative corrected visual acuity was better than that before surgery in 33 eyes(82.5%),and was equal to that before surgery in 7 eyes(17.5%).Conclusions Secondary posterior chamber IOLs implantation was a effective surgery for aphakic eyes in children,but attention should be paid to anti inflammatory treatment and amblyopia treatment.
