The Long-term observation of the quick contrast sensitivity and its influencing factors after SMILE
SMILE demonstrated excellent 7-year outcomes. In the low-to-moderate myopia group, all eyes (100 %) achieved UDVA of 20/25 or better, and postoperative astigmatism was within ±0.50 D. In the high myopia group, 72.5 % achieved UDVA ≥20/25. Greater preservation of corneal thickness was associated with better postoperative contrast sensitivity and visual quality, whereas residual astigmatism and minor decentration were linked to slightly reduced long-term outcomes.
