To demonstrate precision pulse capsulotomy (PPC) in an open-sky procedure and to evaluate its use during triple procedure keratoplasty in small nondilating pupils.
This single-center retrospective case series study included 10 eyes (from 10 patients) with corneal opacity and poorly dilated pupils who were scheduled to undergo triple procedure keratoplasty. The main outcome measures were capsulotomy performance of the PPC device and intraoperative complications. Secondary outcome measures included postoperative best-corrected visual acuity, intraocular pressure, and other postoperative complications.
Complete free-floating capsulotomy was achieved in all 10 eyes. There were no cases of anterior capsule tears or tags. There were no postoperative complications that occurred in association with the PPC device.
The PPC device facilitates creation of a smooth, round, and appropriately sized anterior capsulotomy in open-sky surgeries, particularly in presence of small nondilating pupils.
展示开放式手术中的精密脉冲囊切开术（PPC），并评估其在小瞳孔三联手术角膜移植中的应用。
这是一项单中心回顾性病例系列研究，纳入了 10 只眼（来自 10 位患者），这些眼患有角膜混浊和瞳孔难以扩张，计划进行三联手术角膜移植。主要观察指标是 PPC 设备的囊切开术表现和术中并发症。次要观察指标包括术后最佳矫正视力、眼压和其他术后并发症。
10 只眼中均实现了完全自由浮动的囊切开术。没有前囊撕裂或标签的病例。与 PPC 设备相关的术后并发症为零。
PPC 设备可在开放式手术中轻松、准确地完成圆形、大小合适的前囊切开术，尤其是在小瞳孔的情况下。
