Zepto-rhexis: A new surgical technique of capsulorhexis using precision nano-pulse technology in difficult cataract cases

Abstract

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.
