摘要

目的：评价飞秒激光在白内障手术中角膜主要切口愈合的准确性和质量。方法：该研究是一项前瞻性、非随机、研究者隐匿性研究。在这项前瞻性、非随机的研究中，37例有白内障手术指证的患者共37只眼被分为两组：Femto组，用飞秒激光自动切口（18只眼），Phaco组，用角化刀切口（19只眼）。计划切口为2.2 mm宽，1.65 mm长。比较切口长度、内皮间隙、内皮错位和局部Descemet Membrane脱离（DMD）的发生率。结果：Femto组两次检查的平均切口长度有统计学差异：第一次检查（2 ~ 4天）为1.64 mm±0.16比1.43 mm±0.30 (p = 0.001)，第二次检查（1 ~ 3个月）为1.58 mm±0.22比1.27 mm±0.34 （p < 0.0001）。检查2未见内皮间隙。在检查1中，Femto组的内皮间隙更大。在两次检查中，Femto组的内皮错位较低，而两次检查中Femto组的DMD发生率较低。结论：与人工角膜切割相比，激光自动切口的平均长度更长，DMD患病率更低。

Evaluation of corneal incision in femtosecond laser-assisted phacoemulsification

Purpose

This study aimed to evaluate the accuracy and quality of healing of main corneal incisions in femtosecond laser procedures in cataract surgery.

Methods

It was a prospective, non-randomized, investigator-masked study. A total of 37 eyes of 37 patients with indication for cataract surgery were separated into two groups in this prospective, nonrandomized study: Femto group, with incisions automated by femtosecond laser (18 eyes), and Phaco group, with incisions made using a keratome (19 eyes). The planned incisions were 2.2 mm wide and 1.65 mm long. The length of the incision and prevalence of endothelial gap, endothelial misalignment, and localized Descemet Membrane Detachment (DMD) were compared.

Results

The mean incision length was statistically higher in the Femto group in two examinations: 1.64 mm ± 0.16 vs. 1.43 mm ± 0.30 (p = 0.001) in Exam 1 (between 2 and 4 days) and 1.58 mm ± 0.22 vs. 1.27 mm ± 0.34 (p < 0.0001) in Exam 2 (between 1 and 3 months). No eye presented an endothelial gap in Exam 2. The endothelial gap was higher in the Femto group in Exam 1. In the two examinations, endothelial misalignment was lower in the Femto group, whereas the incidence of DMD was lower in the Femto group in the two examinations.

Conclusions

Automated incisions with femtolaser presented a higher mean length and lower DMD prevalence compared to manual incisions with a keratome.
