Abstract

L'invention concerne une composition de coloration ayant une intensité de coloration améliorée. La composition comprend un colorant vital et de l'acide hyaluronique, le colorant vital comprenant du bleu ciel de Chicago et du bleu de Trypan. La composition de coloration est utilisée pour colorer la capsule du cristallin pendant une chirurgie de la cataracte et fournit un contraste suffisant de telle sorte qu'aucune bulle d'air n'a besoin d'être injectée dans la chambre antérieure pendant une chirurgie de la cataracte.
