To investigate the intraoperative performance and the ultrastructural features of anterior capsulotomy performed with the improved Zepto precision pulse capsulotomy (PPC) device.
Launceston Eye Institute, Launceston, Tasmania, Australia.
Prospective, consecutive case series.
Intraoperative observation of performance and complications were made on consecutive eyes having capsulotomies with the improved PPC device. The capsulotomy specimens were examined under scanning electron microscope and compared with manual continuous curvilinear capsulorhexis and femtosecond laser-assisted cataract surgery specimens.
The study comprised 52 eyes. Intended capsulotomy occurred in 50 eyes with 2 device failures. Complete free-floating capsulotomies were achieved in 48 eyes (96%). Anterior capsule tears occurred in 2 eyes (4%).
The ability of the PPC device to create complete free-floating capsulotomies improved; however, the radial tear rate remained high. The ultrastructural features in ex vivo human capsulotomy specimens still showed areas of irregular capsule margin with frayed edges.
研究使用改良型 Zepto 精密脉冲囊膜切开（PPC）设备进行前囊膜切开术的术中表现和超微结构特征。
澳大利亚塔斯马尼亚州朗塞斯顿眼研究所。
前瞻性、连续病例系列。
对连续行囊膜切开术的患者进行术中表现和并发症的观察，这些患者均使用改良型 PPC 设备进行手术。扫描电子显微镜检查囊膜切开标本，并与手动连续曲线囊膜切开术和飞秒激光辅助白内障手术标本进行比较。
该研究共纳入 52 只眼。50 只眼的预期囊膜切开术成功，2 只眼发生设备故障。48 只眼（96%）实现了完整的游离囊膜切开术。2 只眼（4%）发生前囊膜撕裂。
虽然 PPC 设备创造完整游离囊膜切开术的能力有所提高，但放射状撕裂率仍然较高。体外人囊膜切开标本的超微结构特征仍显示出不规则囊膜边缘和磨损边缘的区域。
