劈核技术在硬核白内障超声乳化手术中的应用

探讨劈核技术在白内障超声乳化手术中的应用。方法采用改良的拦截劈裂技术,对８０例核硬度为Ⅳ级的老年性白内障行超声乳化摘除术。结果术后３个月矫正视力≥０．９者,占７６．２５％。轻度有膜水肿８例,中度角膜水肿２例,后囊破裂１例。

The application of chopping method for phacoemulsification of hard nucleus cataract

OBJECTIVE: The study was designed to investigate the application of chopping method for phacoemulsification of hard nucleus cataract. METHODS: Modified stop and chop technique was used to emulsify the hard nucleus cataract. The degree of nuclear hardness in 80 eyes was grade IV. RESULTS: Postoperatively, the visual acuity with correction was >or= 0.9 in 76.25% at 3 months. There were mild corneal edema in 8 cases, moderate corneal edema in 2 cases and posterior capsular rupture in 1 case. CONCLUSION: The modified stop and chop technique enables the tenacious nuclear plate to rupture easily, thus the stress on the zonules and capsule can be decreased, and in the mean time the technique needs less phaco energy and time.
