■评估和比较飞秒激光辅助白内障手术对LASIK术后和处女眼角膜散光的影响。
■接受飞秒激光辅助白内障手术的患者被纳入研究,并分为两组:A组,包括LASIK术后患者的眼睛,B组,由处女眼睛的患者组成。视敏度,角膜散光,评估手术诱发的散光(SIA)。此外,SIA与术前角膜散光的相关性,平均角膜曲率,和中央角膜厚度也进行了分析。
■本研究共纳入168只眼,A组62只眼,B组106只眼,术后早期两组间角膜散光和SIA比较,差异有统计学意义(P<0.05)。然而,术后6个月差异无统计学意义(P>0.05)。两组术后角膜散光均显示出违反规则的转变。SIA与术前角膜散光之间没有显着相关性,角膜曲率或角膜厚度。此外,两组术后6个月的非矫正视力(UDVA)无显著差异.
■飞秒激光辅助白内障手术对LASIK术后眼和原始眼角膜散光的影响在术后早期是不同的。然而,术后6个月无显著差异。与原始眼睛相比,LASIK后的眼睛表现出延迟的恢复。
UNASSIGNED: To evaluate and compare the effect of femtosecond laser-assisted cataract surgery on corneal astigmatism in post-LASIK eyes and virgin eyes.
UNASSIGNED: Patients who underwent femtosecond laser-assisted cataract surgery were included in the study and categorized into two groups: Group A, consisting of patients with post-LASIK eyes, and Group B, consisting of patients with virgin eyes. Visual acuity, corneal astigmatism, and surgically induced astigmatism (SIA) were evaluated. Additionally, the correlation between SIA and preoperative corneal astigmatism, mean corneal curvature, and central corneal thickness was also analyzed.
UNASSIGNED: A total of 168 eyes were enrolled in this study, with 62 eyes in Group A and 106 eyes in Group B. Significant differences in corneal astigmatism and SIA were observed between the two groups in the early postoperative period following cataract surgery (P<0.05). However, there was no significant difference at 6 months postoperatively (P>0.05). Corneal astigmatism demonstrated an against-The-rule shift in both groups postoperatively. No significant correlation was identified between SIA and preoperative corneal astigmatism, corneal curvature or corneal thickness. Additionally, there was no significant difference observed between the two groups in terms of uncorrected distance visual acuity (UDVA) at 6 months postoperatively.
UNASSIGNED: The effect of femtosecond laser-assisted cataract surgery on corneal astigmatism in post-LASIK eyes and virgin eyes was different in the early postoperative period. However, there was no significant difference at 6 months postoperatively. The post-LASIK eyes exhibited a delayed recovery compared to the virgin eyes.
