Background: The most frequent post-operative complication of pediatric cataract surgery is posterior capsular opacity (PCO) that can obscure the visual axis causing amblyopia in children. Combination surgery and visual rehabilitation might be needed to overcome the complication after pediatric cataract surgery. Case Report: A 4-year-old-girl with a history of congenital cataract came to our tertiary hospital. She had undergone cataract surgery around three years ago. She did not wear any glasses and did not attend any follow-up due to economic circumstances. Examination revealed low vision, exotropia, a good position of IOL (intraocular lens), and fibrotic posterior capsular opacity. She underwent second surgery consisting of membranectomy, secondary posterior capsulotomy, and anterior vitrectomy for both eyes. Post-operative examination revealed sensory deprivation amblyopia on her left eye. Visual rehabilitation such as giving a spectacle and initiating occlusion therapy for two hours each day were given on her right eye. Conclusion: Secondary posterior capsulotomy surgery and visual rehabilitation of the eye after pediatric cataract surgery is needed to achieve better prognosis in patients.
