To evaluate moderate to high astigmatism corrections on the outcomes of SmartSight lenticule extraction for myopic astigmatism with a new femtosecond laser system.
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.
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 ( < .0003).
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. .
评估使用新的飞秒激光系统对中高度散光的近视散光进行 SmartSight 角膜微透镜提取的效果。
在 6 个月的随访中,评估了 292 只连续接受近视散光治疗的眼睛,其散光大小大于 1.00 屈光度(D)。患者的平均年龄为 29 ± 6 岁,平均等效球镜为-5.06 ± 2.20 D,平均屈光性散光大小为 1.74 ± 0.61 D。
6 个月时,散光为 0.10 ± 0.20 D。未矫正和矫正的远视力(UDVA 和 CDVA,分别)均为 0.0 ± 0.1 logMAR。术后 UDVA 与术前 CDVA 之间的差异以及 CDVA 的变化均比术前提高了+0.4 ± 0.7 行(<.0003)。
Smart-Sight 角膜微透镜提取治疗在 6 个月时是安全有效的。结果表明,在治疗近视散光时,中高度散光在 SmartSight 角膜微透镜提取后得到改善。
