■使用扫频源前光学相干断层扫描(SS-OCT)评估和比较常规和飞秒激光辅助白内障手术(FLACS)后人工晶状体(IOL)偏心和倾斜的幅度。
■在这项回顾性观察研究中,我们纳入了接受常规白内障手术或FLACS并植入疏水性1片单焦点IOL的患者.使用SS-OCT测量IOL偏心和倾斜的大小。视敏度,眼内压,球形当量,轴向长度,对比敏感度,术后1个月进行满意度问卷调查。此外,使用波前像差仪进行术后内圆柱测量.分析各参数与IOL偏心或倾斜的相关因素。
■这项研究包括100名患者的100只眼。平均IOL偏心和倾斜为0.21±0.13mm和5.01±1.49°,分别。常规白内障手术(与FLACS相比,P=0.001)和男性(与女性相比,P=0.047)与较高的术后偏心显着相关。术前晶状体直径(P<0.001),术前晶状体倾斜(P=0.007),术前眼压(P=0.027)与术后倾角增高有关。接受FLACS的50只眼显示出平均术后偏心为0.21±0.13mm,倾斜为4.64±1.48°。与常规手术组相比,FLACS组在术后偏心方面存在显着差异(0.30±0.12mm,P<0.001),但不倾斜(5.03±1.35°,P=0.173)。两组术后视力无明显差异。
接受FLACS的患者在术后一个月表现出比接受常规白内障手术的患者更好的IOL分散和倾斜。然而,IOL偏心和倾斜的差异不影响术后视力.
UNASSIGNED: To evaluate and compare the magnitude of intraocular lens (IOL) decentration and tilt following conventional and femtosecond laser-assisted cataract surgery (FLACS) using swept-source anterior optical coherence tomography (SS-OCT).
UNASSIGNED: In this retrospective observational study, we enrolled patients who underwent conventional cataract surgery or FLACS with the implantation of hydrophobic 1-piece monofocal IOL. The magnitude of IOL decentration and tilt were measured using SS-OCT. Visual acuity, intraocular pressure, spherical equivalent, axial length, contrast sensitivity, and satisfaction questionnaire were evaluated before and one-month post-surgery. Additionally, postoperative internal cylinder measurements were obtained using a wavefront aberrometer. Correlation factors between each parameter and IOL decentration or tilt were analyzed.
UNASSIGNED: This study included 100 eyes from 100 patients. Mean IOL decentration and tilt were 0.21 ± 0.13 mm and 5.01 ± 1.49°, respectively. Conventional cataract surgery (versus FLACS, P = 0.001) and male sex (versus female, P = 0.047) were significantly correlated with higher postoperative decentration. Preoperative lens diameter (P < 0.001), preoperative lens tilt (P = 0.007), and preoperative intraocular pressure (P = 0.027) were correlated with higher postoperative tilt. Fifty eyes that underwent FLACS demonstrated mean postoperative decentration of 0.21 ± 0.13 mm and tilt of 4.64 ± 1.48°. Compared with the conventional surgery group, the FLACS group significantly differed in postoperative decentration (0.30 ± 0.12 mm, P < 0.001) but not in tilt (5.03 ± 1.35°, P = 0.173). Postoperative visual acuity did not significantly differ between the two groups.
UNASSIGNED: Patients who underwent FLACS demonstrated better IOL decentration and tilt than those who underwent conventional cataract surgery one-month post-surgery. However, differences in IOL decentration and tilt did not affect postoperative visual acuity.
