Some studies have shown that there is a certain rotation of the eye in the sitting and lying position of the patient. The Visumax system used for the Refractive Lenticule Extraction-Small Incision Lenticule Extraction (ReLEx SMILE) surgery lacks the rotation of eye control function. So, is the ReLEx SMILE surgery for patients with astigmatism safe and effective?
To evaluate the outcomes of the ReLEx SMILE surgery in cases with myopic astigmatism.
The case series included 120 eyes with myopic astigmatism undergoing ReLEx SMILE surgery from January 2018 to November 2018. The distribution of patients for two subgroups based on the power of astigmatism, low astigmatic group (≤ 1.50D) and high astigmatic group (> 1.50D). All patients were measured UDVA, CDVA, refractive sphere, astigmatism and sphere equivalent before and after surgery one week, one month and three months carefully. The astigmatic correction was evaluated by the vectorial analysis Alpins.
The mean efficacy index of the low and high astigmatic group was 1.035 and 1.082 (respectively); the mean safety index was 1.113 and 1.215 (respectively). 93% of eyes in the low astigmatic group had an angle of error (AE) within ± 15 degrees and 100% in high astigmatic group. There was an undercorrection in astigmatic treatment. No complications during and after surgery were recorded.
ReLEx SMILE surgery for the myopic astigmatic treatment was safe and effective.
一些研究表明，患者在坐立和卧位时眼睛存在一定程度的旋转。用于屈光性晶状体切除术-小切口晶状体切除术（ReLEx SMILE）手术的Visumax系统缺乏眼睛旋转控制功能。那么，ReLEx SMILE手术对于散光患者是否安全有效呢？
评估ReLEx SMILE手术治疗近视散光的效果。
该病例系列纳入了2018年1月至2018年11月期间接受ReLEx SMILE手术的120只近视散光眼。根据散光度数将患者分为两个亚组，低散光组（≤1.50D）和高散光组（>1.50D）。所有患者在术后1周、1个月和3个月时仔细测量术前和术后的最佳矫正视力（UDVA）、矫正视力（CDVA）、屈光球镜、散光和等效球镜。通过矢量分析Alpins评估散光矫正情况。
低散光组和高散光组的平均疗效指数分别为1.035和1.082；平均安全指数分别为1.113和1.215。低散光组93%的眼睛误差角（AE）在±15度以内，高散光组为100%。散光治疗存在欠矫情况。手术期间及术后未记录到并发症。
ReLEx SMILE手术治疗近视散光安全有效。
