To investigate early changes in the disk halo under different light conditions after myopic small incision lenticule extraction (SMILE).
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.
At 5 cd/m and 1 cd/m luminance, the halo radius in the high myopia (HM) group reached a postoperative peak after 1 week ( = 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 ( = 0.015), but significantly improved after 3 months ( = 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.
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.
探讨近视性小切口透镜切除术（SMILE）后在不同光照条件下视盘光晕的早期变化。
这项前瞻性研究纳入了70例年龄在18 - 33岁的近视患者的70只眼，等效球镜度（SE）为-5.87±1.86 D，均接受了SMILE手术。术前和术后测量主观验光、高阶像差（HOAs）、瞳孔测量和光晕，以分析视盘光晕变化及相关因素。
在5 cd/m和1 cd/m亮度下，高度近视（HM）组的光晕半径在术后1周达到峰值（分别为=0.000和0.019），3个月后恢复至基线水平。在中低度（LM）近视组，术后1周的光晕半径与术前水平相比无差异（=0.015），但3个月后显著改善（=0.000）。在LM组的所有时间点，光晕半径与SE、未矫正远视力（UDVA）、眼HOAs、彗差和瞳孔光反射相关，但在HM组中无相关性。
SMILE术后早期出现光晕症状，但在3个月内恢复。HM组的恢复过程比LM组慢，且光晕半径与SE、UDVA、眼HOAs、彗差和瞳孔光反射相关。
