Introduction: Posterior polar cataracts (PPCs) present a known risk of posterior capsule rupture during cataract surgery. This is a case of spontaneous posterior capsule rupture in a patient with PPC, without prior trauma or external factors. This observation is crucial for risk assessment in patients with PPC. Patient and Clinical Findings: A 29-year-old man presented with sudden, painless vision loss in right eye. There is no history of trauma or other symptoms. Visual acuity was 1.4 (logMAR) in the right eye and 0.8 in the left. Slitlamp examination revealed a vertical posterior capsular tear and cataract changes in the right eye, with the lens material in the anterior vitreous. The left eye showed a type 2 PPC. Anterior segment optical coherence tomography and ultrasound confirmed the posterior capsule rupture and dislocated lens matter in the right eye. Diagnosis, Intervention, and Outcomes: Given the spontaneous rupture, surgical planning included considerations for potential complications. Imaging supported a diagnosis of progressive PPC, indicating a heightened risk of rupture in the left eye. Conclusions: This case underscores the need for cautious management of PPC due to the risk of preoperative capsule rupture.
