Cataract
Conditions
Brief summary
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.
Detailed description
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.
