In our report, we present the hypersonic vitrectomy (Vitesse, Bausch and Lomb) being employed for anterior vitreous liquefaction and removal in posterior capsular rupture. The capsular tear with nucleus drop during conventional phacoemulsification was managed by vitrectomy using the hypersonic vitrector after posterior-assisted levitation followed by intraocular lens (IOL) implantation. The minimal cortical and epinuclear lens particles in the anterior chamber and vitreous were also liquefied with a stoke length of 30 to 40 μm and aspirated via the Vitesse vitrectomy system. The same probe performs the vitrectomy and the nucleus removal. The postoperative period was uneventful with clear cornea, normal fundus, and 20/20 best-corrected visual acuity (BCVA). The hypersonic vitrectomy utilizes the ultrasound power of 29.5 kHz and a stoke length of 0 to 60 μm for liquefaction of the vitreous. It can be a safe alternative for vitrectomy and lens removal in a single setting.
在我们的报告中,我们介绍了使用高超声速玻璃体切割术(Vitesse,Bausch and Lomb)在前部玻璃体液化和后囊破裂时进行玻璃体切除。在常规超声乳化过程中发生囊膜撕裂伴核下滴时,采用后辅助悬浮法联合高超声速玻璃体切割器进行玻璃体切割,然后植入人工晶状体。采用 30 至 40μm 的冲程长度将前房和玻璃体中的最小皮质和核周晶状体颗粒液化,并通过 Vitesse 玻璃体切割系统抽吸。同一个探头既进行玻璃体切割又进行核切除。术后角膜透明,眼底正常,最佳矫正视力(BCVA)为 20/20。高超声速玻璃体切割利用 29.5 kHz 的超声功率和 0 至 60μm 的冲程长度使玻璃体液化。它可以作为一种安全的替代方法,在单次手术中同时进行玻璃体切割和晶状体切除。
