A 27-year-old male presented with complaints of defective vision in the right eye (RE) for 6 months, associated with a history of trauma to the RE with a fist. Best-corrected visual acuity (BCVA) in the RE was 6/12 and in the left eye (LE) was 6/6. Dilated slit-lamp biomicroscopy in each eye revealed a posterior polar cataract with RE showing preexisting posterior capsular (PC) dehiscence [Figure 1]a. Anterior segment optical coherence tomography (AS-OCT) showed a posterior polar cataract with a defect in posterior capsule (teardrop sign) [Figure 1]b. The patient underwent RE phacoemulsification with implantation of a three-piece foldable posterior chamber intraocular lens (PCIOL) in the ciliary sulcus with reverse optic capture. Intraoperatively, precautions were undertaken to avoid posterior capsule rent enlargement and vitreous prolapse. Postoperatively, BCVA was 6/6, and a well-centered IOL with typical PC dehiscence was seen [Figure 1]c and [Figure 1]d.

| Discussion|| |
Posterior polar cataract (PPC) is characterized as a central bull's eye-shaped opacity located on the posterior capsule. It often presents as one of the most difficult problems for surgeons. Although isolated PC rupture following blunt injury is a rare complication, because of the associated thinning of PC with PPC, traumatic posterior capsule dehiscence can be expected in such cases. In our case, the association could not be confirmed, and the dehiscence might be coincidental.
Preoperatively, several imaging modalities can be used to confirm the integrity of the posterior capsule. These include ultrasound, Scheimpflug imaging, and AS-OCT. Several classification systems for PPC have been described in the literature allowing for prognostication.
It is important to determine this anatomical difference for surgical planning and to assess the likelihood of intraoperative complications. Prevention of extension of the rent and drop of lens material into the vitreous is of imperative importance, and several modifications have been described to prevent the same intraoperatively.
