Posterior capsule rupture with herniated lens fragment in the vitreous cavity on magnetic resonance imaging has not been reported in India until now; however, it has been reported in other countries. Therefore, this study reports the case of a 15-year-old boy presenting with posttraumatic loss of vision in the right eye due to posterior capsular rupture and herniation of lens material into the vitreous cavity, which was detected by B-scan ultrasonography and magnetic resonance imaging as no ophthalmic examination was possible due to the posttraumatic cataract. The patient was treated by lens aspiration with anterior chamber vitrectomy and placement of posterior chamber intraocular lens, with the patient achieving 6/6 visual acuity postoperatively. This case is unusual due to the rarity of the findings, and it highlights the crucial role of imaging in achieving timely diagnosis and surgery to restore vision in the affected eye.
