Update on epikeratophakia in children.

| Abstract |
Epikeratophakia continues to be an extremely attractive option for younger children with unilateral aphakia who are noncompliant users of contact lenses but who are young enough to benefit from amblyopia therapy. The epikeratophakia procedure is much safer than IOL implantation. The epikeratophakia tissue lens is especially useful for children with traumatic aphakia and corneal lacerations because the lens can strengthen and smooth the cornea as well as correct the aphakia. This allows much quicker rehabilitation than could be accomplished with contact lenses. The epikeratophakia procedure may be combined with a cataract extraction and should be in those children with acquired cataracts who demonstrate contact lens noncompliance in an office trial of contact lens insertion before operation. Epikeratophakia should be used with caution in neonates and young infants because of the rapid growth of the eye. Extended-wear contact lenses are a safer option for these children, and epikeratophakia can be performed as a secondary procedure if and when problems with contact lens compliance arise. Surface ocular problems such as uncontrolled dry eyes or severe blepharitis will continue to be incompatible with the survival of epikeratophakia tissue lenses. Children who are treated with high doses of radiation for orbital tumors such as rhabdomyosarcomas invariably develop radiation cataracts, which can occur before the onset of radiation keratitis. These children do not do well with epikeratophakia tissue lenses. Likewise, children with severe metabolic disturbances who are not healthy or gaining weight have a diminished chance of graft healing, as do children with poor vision in whom oculodigital autostimulation produces persistent epithelial defects, which prevent survival of the tissue lens.(ABSTRACT TRUNCATED AT 250 WORDS)
