摘要
目的：评价飞秒激光辅助白内障手术（FLACS）中飞秒激光辅助弓形角膜切开术（FSAK）对散光的矫正效果。方法：回顾性研究纳入连续接受FSAK和FLACS联合手术，角膜散光为0.75 ~ 2.25屈光度(D)的患者。采用Alpines载体分析方法分析3种散光载体：靶诱导散光（TIA）、手术诱导散光（SIA）和差分载体（DV）。计算校正指数（CI）、误差角（AE）、误差幅度（ME）和调整系数（CA）。术前和术后3个月测量角膜散光。结果：共纳入107例患者的129只眼。角膜散光由1.34±0.36 D显著降低至0.69±0.47 D (P)。结论：改良FSAK可有效、安全地降低中国白内障患者的角膜散光。
Evaluating the efficacy of femtosecond laser-assisted arcuate keratotomy in correcting low-to-moderate astigmatism during femtosecond laser-assisted cataract surgery in Chinese patients.
Purpose: To evaluate the astigmatism correcting effect of the femtosecond laser-assisted arcuate keratotomy (FSAK) during femtosecond laser-assisted cataract surgery (FLACS) in Chinese people.
Methods: The retrospective study included consecutive patients who underwent combined FSAK and FLACS, with corneal astigmatism of 0.75 to 2.25 diopters (D). Three vectors of astigmatism were analyzed using the Alpines vector analysis: target-induced astigmatism (TIA), surgically induced astigmatism (SIA), and difference vector (DV). The correction index (CI), angle of error (AE), magnitude of error (ME), and coefficient of adjustment (CA) were calculated. Corneal astigmatism was measured before and 3 months after surgery.
Results: A total of 129 eyes from 107 patients were enrolled. The corneal astigmatism was significantly reduced from 1.34 ± 0.36 D to 0.69 ± 0.47 D (P < 0.001). The TIA was 1.36 ± 0.37 D, the SIA was 1.16 ± 0.69 D, and the DV was 0.7 ± 0.47 D. The ME (difference between SIA and TIA) was - 0.2 ± 0.65 D, and the CI (ratio of SIA to TIA) was 0.86 ± 0.49. The CA (inverse of the CI) was 1.79 ± 1.65. The AE was - 0.02° ± 18.33°. The corneal astigmatism significantly decreased in all axes of astigmatism (P < 0.001). Postoperatively, the residual astigmatism magnitudes were 0.76 ± 0.44 D in with-the-rule (WTR), 0.63 ± 0.51 D in against-the-rule (ATR), and 0.62 ± 0.44 D in oblique (OBL). The CI values were 0.65 ± 0.31, 1.22 ± 0.52, and 0.80 ± 0.40 in WTR, ATR, and OBL, respectively.
Conclusion: The modified FSAK for Chinese cataract patients effectively and safely reduced corneal astigmatism.
期刊介绍：
Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics.
The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
