Zepto precision pulsed capsulotomy is an emerging technology aimed at providing a safer and more reproducible anterior capsulorhexis, with potential advantages in challenging cases. Initial reports suggest high safety, and thus far to our knowledge, no complications have been reported. Herein we report an unexpected complication. After the pulse delivery phase on a routine cataract case, a radial tear of the anterior capsule was observed. Upon careful review of the surgery video, an air bubble was noted, at the precise clock hour of the radial tear, trapped between the device wire and capsule. This air bubble presumably prevented the transfer of rapid phase transition at this site, interfering with capsule cleavage, and resulting in incomplete capsulotomy. Based on this observation, if a trapped air bubble is observed after the vacuum phase, we recommend applying more vacuum or disengaging and reattaching, before proceeding to the pulse delivery stage.

精密脉冲囊切开术并发前囊径向撕裂：一种拟议的机制。

Zepto精密脉冲囊切开术是一种新兴技术，旨在提供更安全，更可重复的前囊撕脱术，在具有挑战性的情况下具有潜在的优势。最初的报告表明安全性很高，据我们所知，迄今尚未发现并发症。在此，我们报告了意外的并发症。在常规白内障病例的脉冲递送阶段之后，观察到前囊的放射状撕裂。仔细查看手术视频后，在径向撕裂的精确时钟时刻发现了气泡，被困在设备线和胶囊之间。据推测，该气泡阻止了该部位的快速相变的转移，从而干扰了胶囊的分裂，并导致不完全的囊切开术。基于此观察结果，如果在真空阶段之后观察到残留的气泡，
