Abstract Details


It is well established that radial tears in the capsulorhexis increase the rate of cataract surgical complications. Despite the appeal of an automated method of creating a perfectly circular anterior capsulotomy, global adoption of femtosecond laser capsulotomy (FSLC) has been limited. Compared to manual continuous curvilinear capsulorhexis (CCC), the FSLC is highly reproducible, uniformly more circular, and has a more precise diameter.


Setting: C.M.A. Centro Microchirurgia Ambulatoriale Monza – Italy


A novel capsulotomy method and technology called PPC and trade named Zepto. The Zepto precision pulse capsulotomy (PPC) technology (Mynosys - Fremont, California) creates a circular anterior capsulotomy of a precise diameter using a disposable handpiece and tip that are used in the normal surgical sequence. A disposable handpiece and nanoengineered capsulotomy tip are powered by a small console to automatically and instantaneously create a perfectly circular capsulotomy of a precise predesigned diameter The tip consists of a circular nitinol ring covered by a thin soft, clear silicone suction cup (SC)-shaped like a miniature inverted frying pan


100 consecutive eyes with cataract underwent surgery with an automated method to perform capsulorhexis. The anterior chamber depth was 2.75 ± 0.33. Endothelial Cells Count preop was 2207 +- 386 and 4 months postop 2122 +- 358 with a 4% lost cells. We experienced 4 anterior radial tears in the first 25 cases.


The Zepto PPC technology creates a precise circular anterior capsulotomy used as part of the normal surgical sequence. This technique allows cataract surgeons to reduce the rate of cataract surgical complications.
