Subtle signs of anterior vitreous face disturbance during posterior capsulorhexis in pediatric cataract surgery.

In 4 patients with congenital cataract, subtle signs of anterior vitreous face (AVF) disturbance were documented during posterior continuous curvilinear capsulorhexis. The signs were vitreous strands in the anterior chamber, vitreous strands attached to the capsule flap, and distortion of the anterior and posterior capsulorhexis margins; the latter is considered a pathognomonic sign of AVF disturbance. As a result of the early recognition, modifications to the cataract surgery technique were made.
