“…Other methods include the use of vitreous cutter needles, superotemporal incisions, stab knives, 25-27 gauge needles, and extremely ne 30G insulin syringe needles for anterior capsulotomy [13,14,15]. Numerous newly reported techniques such as vacuum capsulorrhexis, modi ed two-step methods, and suture needle microcapsulotomy have also been attempted [16,17,18,19].…”

Objective: To effectively avoide the occurrence of the Argentinian flag sign during the process of continuous, circular, and centered anterior capsulotomy (CCC) on the anterior capsule in cortically liquefied intumescent cataracts Methods: Preoperative examinations including slit-lamp examination, ocular A-scan ultrasonography, and UBM were conducted on 61 patients with intumescent cataracts. Cases with cortically liquefied intumescent cataracts were selected and after staining with indocyanine green, the anterior chamber air bubble technique was used to compress the anterior capsule, and liquefied cortex was aspirated using a puncture needle. CDVA and intraocular pressure were recorded on postoperative days 1, 1 week, 1 month, and 6 month. Intraoperative and postoperative complications were documented and analyzed. Results: Fifty eyes were identified as having cortically liquefied intumescent cataracts. No cases of the Argentinian flag sign occurred, and standard capsulorrhexis was achieved, facilitating smooth phacoemulsification. All patients achieved satisfactory outcomes at follow-ups of 1 day, 1 week, 1 month, and 6 month postoperatively. Mild corneal edema was observed in three cases on the first postoperative day, with no other complications noted. Conclusion: The anterior chamber air bubble technique combined with cortical fluid release technique can prevent the occurrence of the Argentinian flag sign in cortically liquefied intumescent cataracts, this method is simple, convenient and economic for the clinical promotion.

“…Here, radial tearing is avoided by puncturing the anterior capsule with a 30 G before capsulorhexis to equalize the pressure of the anterior chamber and the intercrystalline space. The technique was used successfully in 174 cases [51]. A similar technique involving puncturing the capsule before CCC was described by Balyan et al [52] in 60 cases in which the flag sign was avoided.…”

Purpose of reviewSuccessful anterior capsulotomy is an important step in cataract surgery. This article reviews the various anterior capsulotomy techniques available to surgeons to optimize the step, including those that have become available since the introduction of femtosecond-laser-assisted cataract surgery (FLACS). Studies comparing the relative advantages of each technique will be emphasized. Recent findingsManual continuous curvilinear capsulorhexis (CCC) and FLACS remain the two most widely studied techniques for achieving anterior capsulotomy. Each technique has been shown to be effective for a wide range of patients and cataract surgery complications. Meta-analyses have shown that FLACS provides similar results to manual CCC for long-term cataract surgery outcomes. Several alternative methods for anterior capsulotomy have been described, which aim to provide some of the advantages of laser capsulotomy at a lower cost; among these, precision pulse capsulotomy (PPC) and selective laser capsulotomy (SLC) have been investigated the most in the literature so far.

“…It is realized that white, intumescent and hypermature cataracts have a high intracrystalline pressure (ICP). CCC is started in the constant way and because of the conceivable abrupt loss of tension distinction between the ICP, the anterior chamber pressure (ACP) and the vitreous chamber pressure (VCP), there is a danger of a spiral tear towards the periphery of the anterior capsule, with the potential inconveniences of augmentation of the tear to the posterior capsule, loss of vitreous and fall of the nucleus into the vitreous 8 .…”
