Abstract
- PURPOSE
To evaluate the effect of Nd: YAG laser capsulotomy for posterior capsular opacification (PCO) after posterior chamber intraocular lens (PC-IOL) implantation in children. METHODS: Thirty eyes of 23 children underwent Nd: YAG laser capsulotomy for PCO after PC-IOL implantation. The frequency of laser capsulotomy, elapsed time between cataract surgery and capsulotomy, laser parameters, pre and postoperative visual acuity, complications and recurrence were reviewed. RESULTS: From 108 eyes with intact posterior capsule after lensectomy, 30 (27.8%) were treated with Nd: YAG laser capsulotomy. The mean age at Nd: YAG laser capsulotomy was 7 years, the mean follow-up was 27 months, and the time interval between cataract operation and Nd: YAG laser capsulotomy was 13 months. Visual acuities of 20/40 or better were attained in 73% of eyes and visual acuities of 20/60 or less in 10% of eyes. PCO recurred in 12 eyes (40%), 10 of which were treated by performing a second laser capsulotomy, but the other two required a third laser capsulotomy. There was no relationship between the recurrence and the delay to initial laser capsulotomy, the amount of energy used for laser capsulotomy, or the patient age. One eye (3%) had corneal erosion, a bleeding from the pupillary margin and increased IOP; however, all responded well to medical treatment. CONCLUSIONS: Nd: YAG laser capsulotomy for PCO after PCL implantation in children offers a noninvasive and safe capability to create a clear visual axis. Although considered effective, there is a high likelihood that Nd: YAG laser capsulotomy will require revision.
