CataractCoach™ 2648: Rosatelli double capsulorhexis for white cataracts

We love Dr Neto Rosatelli and his incredible surgical skill. An intumescent white cataract poses significant challenges during cataract surgery due to high intralenticular pressure and poor red reflex. The double capsulorhexis technique offers a controlled approach to prevent the dreaded Argentinian flag sign, where the anterior capsule tears radially due to sudden decompression. The procedure begins with staining the anterior capsule using trypan blue dye to enhance visualization. A small, central “mini-capsulorhexis” (approximately 2-3 mm) is created carefully with a cystotome or micro-forceps, allowing controlled egress of liquefied cortical material. Once intralenticular pressure is relieved by aspirating the liquefied lens cortex, viscoelastic is injected to flatten the anterior capsule and stabilize the anterior chamber. The surgeon then enlarges the mini-capsulorhexis into a standard-sized continuous curvilinear capsulorhexis (CCC), ensuring a strong, tear-resistant margin for phacoemulsification. This staged approach minimizes the risk of capsule runout and maintains control over capsular flap dynamics. The double capsulorhexis technique is particularly valuable in cases where pre-operative imaging indicates significant lens swelling and liquefaction. Mastery of this method provides surgeons with a safe, systematic approach to tackling these complex cases, reducing intraoperative complications, and ensuring a stable platform for successful cataract removal and intraocular lens (IOL) implantation.
