To analyze the visual acuity and complications between primary intraocular lens (IOL) implantation and contact lens wearing, this literature search was performed with data on patients with congenital cataract younger than 2 years published in March 2019. Seven identified studies enrolling 675 eyes were selected for analysis. Patients with primary IOL implantation owned better visual acuity than those with aphakia who wore the contact lens (weighted mean difference = 0.161; 95% CI, 0.108-0.214). For visual axis opacification (VAO), primary IOL implantation increases the incidence of VAO compared with contact lens wearing (relative risk = 0.23; 95% CI, 0.13-0.42). No statistically significant difference was found between the 2 groups about the prevalence of glaucoma and strabismus. Primary IOL implantation achieved better visual outcomes after cataract extraction in patients younger than 2 years. In addition, no higher risk for complications among primary IOL implantation compared with contact lens wearing was noted. Therefore, implanting a primary IOL during congenital cataract surgery is a better therapy for children younger than 2 years than wearing a contact lens.
