We describe a phacoemulsification technique for cataracts in eyes with anticipated weak zonular apparatus. After central sculpting, a crater 90% deep is made. A horizontal fracture is created with the phaco probe and chopper. The nucleus is chopped, dividing the inferior hemisection into 2 pie-shaped pieces, which are then emulsified. Without rotating the nucleus, a groove is made at the superior hemisection and a vertical fracture created with the chopper. The bevel of the phaco probe is then turned down to emulsify each quadrant separately. This technique is especially useful in eyes with weakened zonular apparatus such as those with hypermature cataract, uveitis, long-standing glaucoma, trauma, retinitis pigmentosa, and operated retinal detachments.
我们描述了一种用于预期晶状体悬韧带薄弱的眼中白内障的超声乳化技术。在进行中央雕刻后，制作一个深度达90%的凹坑。用超声探头和劈核器制造一条水平骨折线。将核劈开，把下半部分切成2个扇形块，然后进行乳化。不旋转核，在上半部分制作一条凹槽，并用劈核器制造一条垂直骨折线。然后将超声探头的斜面朝下，分别乳化每个象限。该技术在晶状体悬韧带薄弱的眼中特别有用，如过熟期白内障、葡萄膜炎、长期青光眼、外伤、视网膜色素变性以及视网膜脱离手术后的眼睛。
