Puncturing the anterior capsule in a patient with a very soft lens, an elastic capsule, and/or deficient zonular countertraction can be challenging even with a sharp needle or blade. The crossed-swords, capsule-pinch technique capitalizes on opposing forces from 2 needles directed toward each other with a "pinch" of the capsule between their tips. This affords a controlled and facile puncture of the capsule without creating stress on the zonules or anteroposterior displacement of the lens.
在遇到非常软的晶状体、弹性囊袋和/或悬韧带不足的患者时，即使使用锋利的针头或刀片，在前囊膜上穿刺也具有挑战性。交叉剑、囊夹技术利用了 2 根针相互指向的相反力，在针尖之间夹住囊袋，从而实现对囊袋的可控且简便的穿刺，而不会对悬韧带造成压力或使晶状体前后移位。
