Secondary Intraocular Lens Implantation in Pediatric Aphakia

ABSTRACT

A retrospective study was done on secondary intraocular lens implantation in 19 children(22 eyes)who were not satisfied with aphakic glasses and were not tolerant with contact lenses.In all cases,postoperative visual acuity improved or remained at the preoperative level.In 10 cases,postoperative visual acuity was better than 20/40. After at least 12 months of follow-up,average difference of refractive power between the two eyes in the same patient is 0.79 diopter. Early postoperative complications related to secondary intraocular lens implantation were vitreous hemorrhage(1 eye)and IOL decentration. Vitreous hemorrhage was resorbed in three weeks.In case of IOL decentration,we repositioned the IOL.Late complcations during the follow-up period included development of dense capsular opacification in four eyes.They are all treated by NdYAG capsulotomy. After capsulotomy there were some improvement in visual acuity. From these results,secondary intraocular lens implantation appears to be a safe, effective method for correction of aphakic children who are not satisfied with aphakic glasses and/or intolerant of use of contact lenses.
