Waterjet cutting is an advanced technology. It consists of a cutting tool that uses a very thin stream of ultra-high-pressure water forced at high velocity through a very small nozzle, creating a very sharp knife. We report on the first experimental use of waterjet technology to reshape the cornea.
The system was used in vitro on 10 bovine eyes, and in vivo on 10 albino rabbit eyes. Using the waterjet keratome (Lipshitz-Bass knife, LBK) lamellar corneal incisions were performed. Histological examinations were performed.
A waterjet stream was found to be capable of incising corneas at relatively low energy levels (4000 PSI). Good surface quality could be obtained, and there was no collateral damage to the remaining portion of the cornea, lens, or retina. In the in vivo experiments, the epithelium healed within 48 hours.
These preliminary experiments suggest that waterjet technology can be an effective instrument for reshaping the cornea.
水刀切割是一项先进技术。它由一种切割工具组成,该工具使用极细的超高压水流,以高速通过一个非常小的喷嘴,形成一把非常锋利的刀。我们报告了水刀技术首次用于重塑角膜的实验情况。
该系统在10只牛眼上进行了体外实验,并在10只白化兔眼上进行了体内实验。使用水刀角膜刀(利普希茨-巴斯刀,LBK)进行角膜板层切口。进行了组织学检查。
发现水刀流能够在相对较低的能量水平(4000磅力/平方英寸)下切割角膜。可获得良好的表面质量,并且对角膜、晶状体或视网膜的其余部分没有附带损伤。在体内实验中,上皮细胞在48小时内愈合。
这些初步实验表明,水刀技术可以成为重塑角膜的有效工具。
