The risks of semi-femtosecond laser myopia surgery mainly include dry eye syndrome, refractive regression, change of corneal shape, overcorrection or undercorrection, and so on.
1. Dry eye syndrome: If part of the nerve fibers are cut off in the semi-femtosecond laser myopia surgery, the tear secretion will be reduced, and the symptoms of dry eye syndrome, such as dry eyes and foreign body sensation, etc., may occur.
2. Refractive regression: If you don’t pay attention to the rest of your eyes after the semi-femtosecond laser myopia surgery, if you don’t standardize the medication treatment, or if you have a big reaction to the postoperative wound healing, refractive regression may occur, resulting in vision loss.
3. Changes in corneal morphology: Semi-femtosecond laser myopia surgery is operated in the corneal stroma layer, which may cause changes in corneal morphology, resulting in the formation of corneal opacity or opacities, etc.
4. Overcorrection or undercorrection: If there is negligence in the examination before the semi-femtosecond laser myopia surgery, the refractive error may be overcorrected or undercorrected.
The risk of Hemifacial laser myopia surgery does not mean that it will definitely happen, but it cannot be avoided completely either. If you want to have semi-femtosecond laser myopia surgery, it is recommended that you choose a local regular large hospital and have the surgery operated by an experienced and professional surgeon, so as to reduce the risks that the surgery may bring.
