PURPOSE To evaluate visual and refractive outcomes of small incision lenticule extraction (SMILE) for hyperopia. METHODS This was a prospective study of vertex-centered hyperopic SMILE using the VisuMax femtosecond laser (Carl Zeiss Meditec, Jena, Germany). Inclusion criteria were maximum attempted hyperopic meridian of between +1.00 and +7.00 diopters (D). Lenticule parameters were 6.3- to 6.7-mm diameter, 2-mm transition zone, 30-µm minimum thickness, and 120-µm cap thickness. A standard outcomes and stability analysis was performed for the 12-month data, including contrast sensitivity using the Functional Vision Analyzer. RESULTS For the 93 eyes treated, last follow-up was 12 months for 72 eyes (77%) and 3 months for 11 eyes (12%), with 10 eyes (11%) lost to follow-up. Attempted spherical equivalent refraction (SEQ) was +5.61 ± 1.21 D (range: +1.00 to +6.90 D) and cylinder was -1.01 ± 0.64 D (range: 0.00 to -3.50 D). For eyes targeted for emmetropia (n = 37), uncorrected distance visual acuity was 20/40 or better in 95% of eyes. SEQ relative to target was -0.17 ± 0.85 D (range: -2.20 to +3.00 D) at 3 months and -0.19 ± 0.90 D (range: -2.07 to +3.50 D) at 12 months with 53% within ±0.50 D. For 70 eyes with data at 3 and 12 months, the mean change in SEQ was -0.06 ± 0.53 D (range: -2.00 to +1.75 D) and the mean change in keratometry was -0.22 ± 0.48 D (range: -1.00 to +1.00 D). There was one line loss of corrected distance visual acuity (CDVA) in 16% of eyes and no loss of two or more lines. There was no clinically significant change in contrast sensitivity. CONCLUSIONS Refractive and visual outcomes 12 months after SMILE for hyperopia were promising, given the high degree of hyperopia corrected and relatively reduced CDVA in this population. There was good refractive and topographic stability between 3 and 12 months. [J Refract Surg. 2019;35(7):442-450.].

用于远视的小切口小孔晶状体摘除术（SMILE）：12个月的屈光性和视觉效果。

目的评估远视眼小切口小孔摘除术（SMILE）的视觉和屈光结局。方法这是使用VisuMax飞秒激光（Carl Zeiss Meditec，德国耶拿）以顶点为中心的远视SMILE的前瞻性研究。纳入标准为最大尝试远视子午线在+1.00至+7.00屈光度之间（D）。小透镜参数为直径6.3至6.7毫米，过渡区域2毫米，最小厚度30微米，盖厚度120微米。对12个月的数据进行了标准的结果和稳定性分析，包括使用Functional Vision Analyzer进行对比敏感度分析。结果对于接受治疗的93眼，最后一次随访是72眼（77％）为12个月，而11眼（12％）为3个月，其中10眼（11％）被随访。尝试的球面等效折射（SEQ）为+5.61±1.21 D（范围：+1.00至+6.90 D），圆柱为-1.01±0.64 D（范围：0.00至-3.50 D）。对于以正视为目标的眼睛（n = 37），未矫正的远距离视力在95％的眼睛中为20/40或更高。相对于目标的SEQ在3个月时为-0.17±0.85 D（范围：-2.20至+3.00 D），在12个月时为-0.19±0.90 D（范围：-2.07至+3.50 D），其中53％在±0.50 D之内。对于在3个月和12个月时有数据的70只眼，SEQ的平均变化为-0.06±0.53 D（范围：-2.00至+1.75 D），并且角膜曲率的平均变化为-0.22±0.48 D（范围：-1.00至+1.00 D）。16％的眼睛有1条校正远视力（CDVA）丢失，没有2根或更多根丢失。对比敏感度没有临床上的显着变化。结论SMILE远视后12个月的屈光和视力结局是有希望的，鉴于该人群中高度矫正的远视眼和CDVA相对减少。在3到12个月之间有良好的屈光和地形稳定性。[J Refract Surg。2019; 35（7）：442-450。]。
