Strabismus
As Figure 6 shows, 6 studies reported the data on strabismus11,22,31,33-35. There were much fewer infants with strabismus in primary IOL group compared with primary aphakia group after the surgery [OR=0.53, 95% CI: (0.31, 0.90), p=0.19]. Given the unilateral cases or bilateral cases will be a critical factor that contribute to strabismus incidence after congenital cataract surgery, a subgroup analysis was performed. There were much fewer infants with strabismus in primary IOL group compared with primary aphakia group in the unilateral subgroup [OR=0.40, 95% CI: (0.21, 0.79), p=0.46]. No difference was found in the bilateral subgroup.
