Selecting the appropriate surgical approach for congenital cataracts presents challenging for ophthalmologists. This prospective, randomized controlled study aims to compare the prognosis of posterior continuous curvilinear capsulorhexis (PCCC) with or without anterior vitrectomy (A-Vit) in treating congenital cataracts.
