"White-puncture": A simple technique to prevent tearing of the anterior capsule during capsulorhexis in intumescent white cataracts.

Abstract

In order to avoid radial tearing of the anterior capsule while performing continuous circular capsulorhexis (CCC) in a white intumescent cataract, called the "Argentinian flag sign" when CCC is associated with a previous capsular stain with trypan blue, an initial puncture of the anterior capsule is performed with a 30G needle as the first step of the surgical procedure, that means, prior to any previous aperture of the anterior chamber. This act seems to allow the pressure of the intracrystalline space and the pressure of the anterior chamber to be equalized, as the liquefied content of the intumescent white cataract is released into a presumably hermetic anterior chamber, avoiding the dreaded anterior capsular radial tear. This technique, called "white-puncture", has been used in 174 cases without any associated complications.
