Abstract

Purpose: To assess visual and refractive outcomes of 1,500 eyes that underwent small incision lenticule extraction (SMILE) with the VisuMax 800 femtosecond laser (Carl Zeiss Meditec AG).

Methods: This retrospective study includes 1,500 eyes of 770 patients younger than 45 years with corrected distance visual acuity (CDVA) of 20/20 or better who were treated with SMILE using the VisuMax 800. The surgery was performed by an experienced surgeon using a standard technique and 3-month follow up data were analyzed.

Results: A total of 1,500 eyes of patients with a mean age of 27.25 ± 4.746 years (39.5% men and 60.52% women) were included in this study. At 3 months, 98% of eyes had uncorrected distance visual acuity (UDVA) of 20/20 or better with an efficacy index of 1.011. Mean preoperative spherical equivalent (SE) was -4.170 ± 1.860 and -0.025 ± 0.120 diopters (D) at 3 months (P < .001). A total of 18.4% gained one line of CDVA and 9.2% lost one line with a safety index of 1.085. Postoperative SE was within ±0.50 and ±1.00 D in 99% and 100% of eyes, respectively. A total of 98.4% and 100% of eyes showed astigmatism of 0.50 and 1.00 D or less, respectively. No eyes lost two or more lines of CDVA. At 3 months, the Objective Scatter Index score was 0.844 ± 0.486, which was close to preoperative values (0.733 ± 0.871), with a mean change of 0.11. Subgroup analysis was done based on grade of myopia and age.

Conclusion: The VisuMax 800, with centration guidance (CentraLign) and cyclotorsion adjustment features (OcuLign), showed safe and effective outcomes for the treatment of myopia and myopic astigmatism in a large cohort of 1,500 eyes.

VisuMax 800小切口晶状体摘除术1500眼视力及屈光效果观察。

目的：评估使用VisuMax 800飞秒激光（卡尔蔡司Meditec AG）进行小切口晶状体摘除术（SMILE）的1500只眼睛的视力和屈光结果。方法：采用VisuMax 800进行SMILE治疗的年龄小于45岁、矫正距离视力（CDVA）为20/20及以上的患者770例，1500只眼进行回顾性研究。手术由经验丰富的外科医生使用标准技术进行，并对3个月的随访数据进行分析。结果：纳入患者1500只眼，平均年龄27.25±4.746岁，其中男性占39.5%，女性占60.52%。3个月时，98%的眼未矫正距离视力（UDVA）在20/20及以上，疗效指数为1.011。术前3个月平均球面等效度（SE）分别为-4.170±1.860和-0.025±0.120屈光度(D) （P < 0.001）。CDVA上涨1条线的占18.4%，下跌1条线的占9.2%，安全指数为1.085。99%和100%的眼睛术后SE分别在±0.50和±1.00 D以内。散光≤0.50 D的占98.4%，小于1.00 D的占100%。没有眼睛失去两行或更多的CDVA。3个月时，客观散射指数评分为0.844±0.486，与术前值（0.733±0.871）接近，平均变化0.11。根据近视程度和年龄进行亚组分析。结论：VisuMax 800具有聚焦引导（CentraLign）和旋扭调节功能（OcuLign），在1500只眼的大队列研究中显示出安全有效的治疗近视和近视散光的效果。
