Intra-ocular lens implantation in children
Ahmadieh H; Javadi MACurrent Opinions in Ophthalmology 2001; 12: 30-34
Intraocular lens (IOL) implantation in the growing eye of a young child brings several problems unique to this age group. Better understanding of the rate of refractive growth in children's pseudophakic eyes may help to predict future refractions in these eyes more accurately. Opacification of the posterior capsule, if it remains intact, interferes with visual rehabilitation in children. Primary posterior capsulectomy and anterior vitrectomy provides clarity of the visual axis. Optical rehabilitation of children with unilateral aphakia is usually problematic. Posterior chamber IOLs are preferred to anterior-chamber IOLs for secondary implantation. In the absence of adequate capsular support and in cases of contact lens intolerance, a scleral-fixated IOL can be implanted. Scleral fixation of a posterior chamber IOL has encouraging short-term results, but the long-term risks are not yet known. IOL implantation in infants is associated with major complications and is not recommended at present. The occurrence of open-angle glaucoma is a sight-threatening, late complication of pediatric cataract surgery. IOL implantation plays a protective role against aphakic glaucoma in children.
