Several techniques are used to make a capsulorhexis in white mature cataract cases as needle cystotome, Utrata capsulorhexis forceps, microincision capsulorhexis forceps, femtosecond Laser, etc. Zepto precision nano-pulse capsulotomy device (Mynosys Cellular Devices; Fremont, CA, USA) is Food and Drug Administration approved, a disposable capsulotomy device that uses low-energy pulses to create a precise central capsulorhexis, independent of pupil size, corneal clarity, or lens density. In this article, the authors report their experience of performing anterior circular curvilinear capsulorhexis with Zepto precision nano-pulse capsulotomy device in challenging cataract cases done at our center. The Zepto handpiece device was inserted through 2.8 mm clear corneal incision. Results of our study in 3 cataract cases (intumescent cataract, morgagnian cataract, and cataract with small pupil) revealed that the precision pulse capsulotomy technology mechanically and simultaneously cleaves all 360° of the apposed capsule of without cauterizing it, creating CCC of 5.2 mm size.
在白色成熟白内障病例中，有几种技术可用于制作囊膜环形撕囊，如针状晶状体囊切开刀、Utrata 囊膜环形撕囊镊、微创晶状体囊膜环形撕囊镊、飞秒激光等。Zepto 精密纳米脉冲囊膜切开装置（Mynosys Cellular Devices；弗里蒙特，加利福尼亚州，美国）已获得美国食品和药物管理局批准，是一种一次性囊膜切开装置，它使用低能量脉冲来创建精确的中央囊膜环形撕囊，独立于瞳孔大小、角膜清晰度或晶状体密度。在本文中，作者报告了他们在中心进行的具有挑战性的白内障病例中使用 Zepto 精密纳米脉冲囊膜切开装置进行前环形曲线囊膜环形撕囊的经验。Zepto 手持设备通过 2.8mm 透明角膜切口插入。在我们的 3 例白内障病例（膨胀性白内障、莫干型白内障和小瞳孔白内障）中的研究结果表明，精密脉冲囊膜切开技术机械地同时切开无灼伤的所有 360°对合囊膜，形成 5.2mm 大小的 CCC。
