Biomechanical control of continuous curvilinear capsulorhexis: a structured video-based analysis of error patterns and recovery maneuvers.

Ten of these cases were purposively selected for detailed analysis on the basis of educational relevance.

In these 10 videos, the most salient error pattern assigned by the author was a small or poorly mobile flap in 5 cases, traction-vector misalignment in 4, and inadequate pivoting in 1; these proportions describe the selected sample only.

A continuous capsulorhexis was completed in all 10 cases, and in-the-bag intraocular lens implantation was achieved in all 50 procedures.

In an inter-observer analysis by two blinded assessors, agreement was high for the final outcome and low for the primary error pattern.
