Optical Correction of Aphakia in Children

There are several reasons for which the correction of aphakia differs between children and adults. First, a child's eye is still growing during the first few years of life and during early childhood, the refractive elements of the eye undergo radical changes. Second, the immature visual system in young children puts them at risk of developing amblyopia if visual input is defocused or unequal between the two eyes. Third, the incidence of many complications, in which certain risks are acceptable in adults, is unacceptable in children. The optical correction of aphakia in children has changed dramatically however, accurate optical rehabilitation and postoperative supervision in pediatric cases is more difficult than adults. Treatment and optical rehabilitation in pediatric aphakic patients remains a challenge for ophthalmologists. The aim of this review is to cover issues regarding optical correction of pediatric aphakia in children; kinds of optical correction, indications, timing of intraocular lens (IOL) implantation, types of IOLs, site of implantation, IOL power calculations and selection, complications of IOL implantation in pediatric patients and finally to determine the preferred choice of optical correction. However treatment of pediatric aphakia is one step on the long road to visual rehabilitation, not the end of the journey.
