白内障超声乳化技术分为单手法和双手法，单手法一般适用于I－II组硬度的晶状体核，III级以上的晶状体核以双手法操作为宜。所谓双手法即用一个辅助钩（phacoChop），帮助掰开或转动晶状体核，以利于超声探头的工作。目前，国内尚无这一辅助钩的生产，国外产品价格昂贵。我科用 Cataract phacoemulsification technology is divided into single-handed method and two-handed method, single-handed method generally applies to I-II group of hardness of the lens nucleus, III above the lens nucleus operating with two methods is appropriate. The so-called two-pronged approach is to use a phantom hook (phacoChop) to help break apart or rotate the lens nucleus to facilitate the ultrasound probe’s work. At present, there is no such auxiliary hook production in China, and foreign products are expensive. My department
