Congenital cataract is the main cause of form deprivation amblyopia in children. Current studies confirm that form deprivation amblyopia affects the macular development. However, there are different opinions about the effect of amblyopia on the macular thickness . Investigators have performed "cataract extraction with IOL implantation" on children with bilateral and unilateral congenital cataract. Investigators used OCT biometry to measure children's the macular thickness before and after surgery..Average sectional total thickness was automatically determined by the instrument's software using a modified Early Treatment Diabetic Retinopathy Study (ETDRS) circle grid (fovea, inner ring, and outer ring: 1 mm, 3 mm, and 6 mm. Investigators dynamically observed changes in macular to explore the retinal mechanism of form deprivation amblyopia and help guide the clinical correct understanding of postoperative follow-up time.
