Purpose

Femtosecond laser arcuate keratotomy (FS-AK) and toric intraocular lens (IOL) implantation are effective for the correction of eyes with corneal astigmatism. In this study, the postoperative refractive outcomes of patients receiving femtosecond laser-assisted cataract surgery (FLACS) with FS-AK and patients receiving standard phacoemulsification with toric IOL implantation were evaluated.

Methods

This retrospective study reviewed the postoperative outcomes of patients undergoing FLACS with FS-AK (the FS-AK group) and patients undergoing standard phacoemulsification with toric IOL implantation (the toric IOL group). The main outcome measures were uncorrected and corrected visual acuities, keratometric and refractive astigmatism, and vector analysis.

Results

The FS-AK group included 41 eyes with preoperative keratometric astigmatism of − 1.64 ± 0.42 diopters (D), and the toric IOL group included 53 eyes with preoperative keratometric astigmatism of − 2.29 ± 0.91 D (P < 0.001). Postoperative refractive astigmatism was comparable between the two groups. Compared with the FS-AK group, postoperative uncorrected visual acuity was significantly better (P = 0.005) and corrected visual acuity was marginally better in the toric IOL group (P = 0.051). The absolute angles of error were 9.95° ± 9.57° and 5.08° ± 4.94° (P = 0.02) in the FS-AK and the toric IOL groups, respectively.

Conclusion

Both FLACS with FS-AK and standard phacoemulsification with toric IOL implantation are safe and effective methods for astigmatism correction during cataract surgery. Standard phacoemulsification with toric IOL implantation achieves better visual acuity than FLACS with FS-AK at the 6-month follow-up.

飞秒激光辅助白内障手术联合弧形角膜切开术和标准超声乳化联合复曲面人工晶状体植入术的屈光效果

目的

飞秒激光弧形角膜切开术（FS-AK）和复曲面人工晶状体（IOL）植入对角膜散光眼的矫正是有效的。在这项研究中，评估了接受 FS-AK 飞秒激光辅助白内障手术 (FLACS) 的患者和接受标准超声乳化术和复曲面人工晶状体植入术的患者的术后屈光结果。

方法

这项回顾性研究回顾了接受 FLACS 的 FS-AK 患者（FS-AK 组）和接受标准超声乳化术并植入 Toric IOL 的患者（Toric IOL 组）的术后结果。主要结果测量是未矫正和矫正视力、角膜曲率和屈光散光以及矢量分析。

结果

FS-AK 组包括 41 只眼，术前角膜散光为 - 1.64 ± 0.42 屈光度（D），复曲面 IOL 组包括 53 只眼，术前角膜散光为 - 2.29 ± 0.91 D（P  < 0.001）。术后屈光散光在两组之间具有可比性。与FS-AK组相比，复曲面人工晶状体组术后裸眼视力明显改善（P  =0.005），矫正视力略好（P  =0.051）。FS-AK 组和复曲面 IOL 组的绝对误差角分别为 9.95° ± 9.57° 和 5.08° ± 4.94° ( P  = 0.02)。

结论

采用 FS-AK 的 FLACS 和标准的白内障超声乳化术联合复曲面人工晶状体植入术都是白内障手术中散光矫正安全有效的方法。在 6 个月的随访中，标准超声乳化联合复曲面 IOL 植入比 FLACS 联合 FS-AK 获得更好的视力。
