This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a newer laser system (VisuMax 800) works better than an older one (VisuMax 500) for correcting nearsightedness through a type of surgery called SMILE. In SMILE surgery, the laser reshapes the cornea to improve vision without creating a flap. The study will compare how well each system works by having one eye treated with each laser.
The newer laser system has several technical improvements that might make the surgery faster or more precise, but doctors don't yet have direct evidence showing whether these improvements actually lead to better patient outcomes. This trial will provide that comparison.

You would undergo bilateral SMILE surgery (both eyes) in one or more visits. One eye would be treated with the VisuMax 500 laser and the other eye with the VisuMax 800 laser (randomly assigned). You would have preoperative measurements, the surgical procedures themselves, and multiple follow-up visits to assess your vision, eye health, and how your corneas respond to surgery. The study will also analyze your tears and tissue samples to understand how each laser affects your eye at a deeper level.
