The purpose of prospective cohort study is to estimate the rate of change in postoperative change after primary IOL implantation among children with congenital cataract(CC) and to explore key factors associated with the rate of change.
Due to myopic shift, it's difficult to select power of IOL implanted in eye with congenital cataract. The developmental profile of refraction among patient with congenital catarat is has not yet been fully characterized. The investigator recruited a large cohort of Chinese CC children.After primary IOL implatation, routine examinations including retinoscopy were completed. Data were analysed to to estimate the rate of change in postoperative change after primary IOL implantation among children with congenital cataract and to explore key factors associated with the rate of change.
1,701 studies on the registry are indexed under Cataract; 230 are open to participants now.
This study's enrollment of 335 is above the median of 81 across 484 observational studies indexed under Cataract.

CC patients underwent surgery of cataratc extraction and primary intraocular lens (IOL) implantation at the Zhongshan Ophthalmic Center between 2010 and 2016 were recruited.
