Robert Weinstock, MD, shares a case of unintended posterior capsular tear. Trypan blue is instilled to stain capsule in the dense cataract with fibrous capsular membrane. The rhexis starts to run peripherally but Dr. Weinstock is able to complete a 360 degree capsulorhexis. Using the irrigating chopper, he deconstructs the quadrants with a combined cracking and chopping technique with high vacuum. The surgeon notes the hallmark sign of a compromised posterior capsule, but with the bimanual technique and keeping irrigation superiorly, all the nuclear fragment remain high in the anterior chamber. After all nuclear fragments are removed, Dr. Weistock performs a limited anterior vitrectomy.
