Abstract

La présente invention porte sur un perfectionnement apporté aux caractéristiques de la pointe existante avec une gradation externe sur la pointe. L'invention a quatre bandes chacune de 0,2 mm de large et d'espacement de 0,2 mm en partant de 2,0 mm à partir de la pointe. Ceci signifie que la bande 1 est de 2,0 à 2,2 mm, la bande 2 est de 2,4 à 2,6 mm, la bande 3 est de 2,8 à 3,0 mm, la bande 4 est de 3,2 à 3,4 mm. L'étalonnage mentionné peut être appliqué à toutes les pointes disponibles avec des modifications mineures dans des pointes à paroi mince et des pointes angulées. L'invention mesure la profondeur réelle pénétrée, en fonction de la profondeur désirée (mathématiquement préétablie), pendant une phaco-émulsification, élimine ainsi à la fois l'hésitation et le trop grand enthousiasme pendant la phaco-chop.
