Additionally, the investigators will evaluate the proportions of patients with postoperative SE within ±0.50D and ±1.0D, as well as postoperative cylindrical power within ±0.50D and ±1.0D, to assess the efficacy and safety of the SMILE 4.0-VISULYZE system in treating refractive errors.",[76,77],"Refractive Surgery","Myopia; Refractive Error","2025-05-22",{"date":80,"type":81},"2025-05-28","ACTUAL",{"date":83,"type":81},"2024-11-01",{"date":85,"type":70},"2026-12-31",{"name":5,"class":6},2]
