Purpose: To evaluate the efficacy and safety of a closed-chamber air bubble capsulotomy
technique to prevent the Argentinean flag sign (AFS) in patients with white and intumescent
cataracts.
Setting: Sohag University, Faculty of Medicine, Ophthalmology Department, Sohag, Egypt.
Design: Prospective interventional noncomparative case series.
Methods: Eighty-two eyes of 80 patients with white and intumescent cataracts were
included. Eyes with any ocular pathology other than cataract or eyes subjected to previous
intraocular surgery were excluded. Needle capsulorhexis was performed under a large air
bubble tamponade without capsular staining. Efficacy of the technique was assessed intraoperatively
by successful completion of capsulorhexis. Safety of the technique was assessed
by the occurrence of intraoperative or postoperative complications.
Results: Complete capsulorhexis by the closed-chamber air bubble technique was successful
in 75 eyes (91.5%), while capsulorhexis extension occurred in seven eyes. In four eyes with
extension, the procedure was shifted to the standard technique of CCC (circular curvilinear
capsulorhexis), using a viscoelastic device. A shift to extracapsular cataract extraction
(ECCE) surgery occurred in the remaining three eyes, as the extension was so far-gone.
No intraoperative or postoperative complications were observed.
Conclusion: The closed anterior chamber air bubble technique for capsulorhexis is a novel,
safe, and effective technique to prevent AFS in white and intumescent cataracts. It is also
time-saving and cost-effective, with less likelihood of capsulorhexis extension. The technique
is considered a valuable addition to previously described techniques.
