More and more myopic friends choose the small incision minimally invasive full femtosecond SMILE surgery to remove their glasses, but also often asked what issues should be noted before surgery. For example, soft contact lenses should be stopped for more than 2 weeks, and the preoperative medication should be adjusted according to the corneal topography examination results. Secondly, the preoperative preparation will also have an indirect effect on the outcome of the surgery. Before the surgery, the medical staff will give a more detailed preoperative guidance program, but the surgery will be nervous, and the slightest shaking of the eyes may have an impact on the outcome of the surgery, which requires a few days before the surgery to do the fixation training, the longer the fixation, the better the surgical result. Then again, if you can calm your mind and adjust your nervousness during the surgery, there is no reason not to succeed!
