In this prospective study , a cohort of 91 eyes with congenital cataract and 25 eyes normal eyes from Wenzhou medical university was erolled.91 eyes with congenital cataract was after lensectomy and anterior vitrectomy as test group, 25 normal eyes as control group. The a- and b-wave and PhNR related parameters was evaluated.

Full description

Secondary IOL implantation in aphika children and lensectomy and anterior vitrectomy and primary IOL implantation in children with congenital cataract were both performed by the same surgeon(Z.Y.E).

electroretinography and photopic negative response are performed to each patient.The research was to evaluate the relationship between the best corrected visionn and the related parameters of a- and b-wave and PhNR .
