Can SMILE surgery correct astigmatism?

For children diagnosed with hyperopic astigmatism, early correction is strongly recommended. Delayed treatment may exacerbate symptoms and lead to further deterioration of vision. In severe cases, corrective outcomes are often suboptimal. Therefore, prompt detection and timely intervention are essential. So, can SMILE (Small Incision Lenticule Extraction) surgery treat astigmatism?

Can SMILE Surgery Treat Astigmatism?

Yes, SMILE laser surgery can effectively treat astigmatism and is currently one of the most commonly used surgical approaches for this condition. Astigmatism is a prevalent ophthalmic disorder classified under refractive errors. It typically arises from congenital developmental abnormalities, poor visual habits, ocular trauma, or corneal scarring following ocular surface infections. These factors cause an imbalance in refractive power between the vertical and horizontal meridians of the cornea, preventing incoming light rays from converging into a single, sharp focal point on the retina—instead forming a focal line—which results in blurred or distorted vision.

SMILE laser surgery corrects corneal refractive defects, thereby improving visual acuity. Currently, refractive surgery remains the only definitive treatment for true myopia. This procedure offers several advantages, including high safety, short operative time, excellent precision, and rapid visual recovery—allowing patients to select the most suitable option based on their individual circumstances.

If you notice any symptoms suggestive of eye disease in daily life, seek medical evaluation promptly and actively cooperate with your ophthalmologist’s treatment plan. We hope this information has been helpful to you.
