Abstract

Purpose: To evaluate moderate to high astigmatism corrections on the outcomes of SmartSight lenticule extraction for myopic astigmatism with a new femtosecond laser system.

Methods: Two hundred ninety-two eyes consecutively treated for myopic astigmatism with astigmatism magnitude greater than 1.00 diopter (D) were evaluated at the 6-month follow-up visit. The mean age of the patients was 29 ± 6 years with a mean spherical equivalent of -5.06 ± 2.20 diopters (D) and a mean magnitude of refractive astigmatism of 1.74 ± 0.61 D.

Results: At 6 months, astigmatism was 0.10 ± 0.20 D. Uncorrected and corrected distance visual acuities (UDVA and CDVA, respectively) were both 0.0 ± 0.1 logMAR. Differences between postoperative UDVA and preoperative CDVA and the change in CDVA were both +0.4 ± 0.7 lines better than preoperatively (P < .0003).

Conclusions: Lenticule extraction treatment using Smart-Sight is safe and efficacious at 6 months. Findings suggest that moderate to high astigmatism improves after SmartSight lenticule extraction in the treatment of myopic astigmatism. [J Refract Surg. 2024;40(5):e328-e335.].

使用 SCHWIND ATOS 对术前散光大于 1.00 Diopter 的复性近视散光进行 SmartSight 矫正：回顾性病例系列。

目的：评估中高度散光矫正对使用新型飞秒激光系统进行 SmartSight 光阑摘除术治疗近视散光效果的影响：连续治疗散光度数大于 1.00 屈光度 (D) 的近视散光患者 292 例，在 6 个月随访时进行了评估。患者的平均年龄为 29 ± 6 岁，平均球面等效度数为 -5.06 ± 2.20 屈光度 (D)，平均屈光散光幅度为 1.74 ± 0.61 D：术后 6 个月，散光度数为 0.10 ± 0.20 D。未矫正视力（UDVA）和矫正远视力（CDVA）均为 0.0 ± 0.1 logMAR。术后 UDVA 和术前 CDVA 之间的差异以及 CDVA 的变化均比术前提高了 +0.4 ± 0.7 线（P < .0003）：结论：使用 Smart-Sight 进行扁平苔藓摘除治疗在 6 个月后安全有效。研究结果表明，SmartSight 光阑摘除术治疗近视散光后，中高度散光得到改善。[J Refract Surg. 2024;40(5):e328-e335]。

期刊介绍： The Journal of Refractive Surgery, the official journal of the International Society of Refractive Surgery, a partner of the American Academy of Ophthalmology, has been a monthly peer-reviewed forum for original research, review, and evaluation of refractive and lens-based surgical procedures for more than 30 years. Practical, clinically valuable articles provide readers with the most up-to-date information regarding advances in the field of refractive surgery. Begin to explore the Journal and all of its great benefits such as: • Columns including “Translational Science,” “Surgical Techniques,” and “Biomechanics” • Supplemental videos and materials available for many articles • Access to current articles, as well as several years of archived content • Articles posted online just 2 months after acceptance.
