Abstract：
OBJECTIVE: To investigate early changes in the disk halo under different light conditions after myopic small incision lenticule extraction (SMILE).
METHODS: This prospective study included 70 eyes of 70 myopic patients aged 18-33 years, with a spherical equivalent (SE) of -5.87 ± 1.86 D, who underwent SMILE. The subjective refraction, higher-order aberrations (HOAs), pupillometry, and halo were measured preoperatively and postoperatively to analyse disk halo variations and correlated factors.
RESULTS: At 5 cd/m2 and 1 cd/m2 luminance, the halo radius in the high myopia (HM) group reached a postoperative peak after 1 week (p = 0.000 and 0.019, respectively), and recovered to baseline after 3 months. In the low-to-moderate (LM) myopia group, the halo radius did not differ 1 week postoperatively compared to the preoperative level (p = 0.015), but significantly improved after 3 months (p = 0.000). The halo radius correlated with SE, uncorrected distance visual acuity (UDVA), ocular HOAs, coma, and the pupillary light reflex in the LM group at all time points, but there were no correlations in the HM group.
CONCLUSIONS: Halo symptoms occurred early after SMILE, but recovered within 3 months. The recovery process was slower in the HM group than in the LM group, and the halo radius correlated with SE, UDVA, ocular HOAs, coma, and the pupillary light reflex.

摘要：
目的：探讨不同光照条件下近视小切口微透镜摘除（SMILE）后椎间盘晕的早期变化。
方法：这项前瞻性研究包括70名年龄在18-33岁的近视患者的70只眼，球面当量(SE)为-5.87±1.86D，接受微笑的人。主观折射，高阶像差(HOAs)，瞳孔测量,术前和术后测量和晕轮，以分析椎间盘晕轮变化和相关因素。
结果：在5cd/m2和1cd/m2亮度下，高度近视（HM）组的晕圈半径在术后1周后达到峰值（p分别为0.000和0.019），3个月后恢复至基线。在低至中度（LM）近视组中，与术前水平相比，术后1周的晕圈半径没有差异（p=0.015），但3个月后明显改善（p=0.000）。晕圈半径与SE相关，非矫正视力（UDVA），眼HOAs,昏迷,LM组在所有时间点的瞳孔反射，但HM组没有相关性。
结论：微笑后早期出现晕症状，但在3个月内康复。HM组的恢复过程比LM组慢，和与SE相关的晕圈半径，UDVA,眼HOAs,昏迷,和瞳孔光反射.
