To compare the utility of precision pulse capsulotomy (PPC) with manual capsulorhexis for capsulotomy in white cataracts.
Hospital-based academic practice.
Retrospective analysis of surgical case records and surgical videos from a single surgeon.
Cases involving intumescent and nonintumescent white cataracts were identified. Capsulotomy outcomes, surgical outcomes, procedural time, and resource utilization, as well as patient demographic and health data, were analyzed and subjected to statistical testing.
15 cases of white cataract (10 intumescent and 5 nonintumescent) performed using continuous curvilinear capsulorhexis (CCC) were compared with 20 cases (9 intumescent and 11 nonintumescent) performed using PPC. The cases covered a period of 14 months before and 30 months after surgeon adoption of PPC. There were no significant differences between the 2 groups in patient age, sex, ethnicity, ocular history, medical history, and medications. PPC resulted in complete capsulotomies without tags or tears and intracapsular intraocular lens implantation with 360-degree capsular overlap in all 20 cases. There was 1 CCC case resulting in the Argentinian flag sign. Compared with CCC, PPC white cataract cases also demonstrated significant advantages in capsulotomy time, reduced use of trypan blue and ophthalmic viscosurgical device, and less overall procedural time.
PPC is a safe and highly effective method to create consistent capsulotomies in both intumescent and nonintumescent white cataracts. The use of PPC provides benefits of significant reductions in capsulotomy time, overall procedural time, and resource utilization, resulting in a streamlined treatment of these complex cataract surgery cases.
比较精准脉冲囊膜切开术（PPC）与手动囊膜切开术在白内障囊膜切开术中的应用效果。
基于医院的学术实践。
对一位外科医生的手术病历记录和手术视频进行回顾性分析。
确定涉及膨胀性和非膨胀性白内障的病例。分析囊膜切开术结果、手术结果、手术时间和资源利用情况，以及患者的人口统计学和健康数据，并进行统计检验。
15 例白内障（10 例膨胀性，5 例非膨胀性）采用连续曲线囊膜切开术（CCC）进行比较，20 例（9 例膨胀性，11 例非膨胀性）采用 PPC 进行比较。这些病例涵盖了外科医生采用 PPC 前后 14 个月和 30 个月的时间。两组患者在年龄、性别、种族、眼部病史、病史和用药方面无显著差异。在 20 例 PPC 手术中，所有病例均实现了完整的囊膜切开，无标签或撕裂，并且植入了 360 度囊膜重叠的人工晶状体。在 1 例 CCC 手术中出现了阿根廷国旗征。与 CCC 相比，PPC 白内障病例在囊膜切开时间、减少使用锥蓝和眼科粘弹剂以及整体手术时间方面也具有显著优势。
PPC 是一种安全且高效的方法，可在膨胀性和非膨胀性白内障中创建一致的囊膜切开。PPC 的使用具有显著减少囊膜切开时间、整体手术时间和资源利用的优势，为这些复杂白内障手术病例的治疗提供了便利。
