Ultrasonography in the refraction of aphakic infants.

Modern management of congenital cataracts which interfere with vision consists of early removal of the cataract and correction of the refractive error by contact lenses or glasses (Parks and Hiles, I967; Von Noorden, Ryan, and Maumenee, I970). Skiascopic postoperative refraction of aphakic infants cannot always be performed satisfactorily because the opening is sometimes small and irregular and no reflex can be seen. We, therefore, suggest that refractive error may be determined by calculation from ultrasonographic measurements.
