In this multicenter, prospective, interventional, single-arm clinical trial, the aim is to determine safety and efficacy of CLEAR using the FEMTO LDV Z8 in Chinese patients in China. The primary objective is to evaluate the visual outcome after CLEAR using the FEMTO LDV Z8 in myopia and astigmatic myopia at the time point, when stability of manifest refraction spherical equivalent (MRSE) is reached. The corresponding hypothesis is that the percentage of treated eyes with satisfactory Uncorrected Distance Visual Acuity (UCDVA) at the point when stability of MRSE is reached after CLEAR is at least 85% of all treated eyes. This hypothesis has been chosen in line with the recommendations of the "Checklist of Information Usually Submitted in an Investigational Device Exemptions (IDE) Application for Refractive Surgery Lasers" issued by the FDA. The secondary objectives are to evaluate the efficacy and safety with respect to stability, predictability, device defects and adverse events of CLEAR using the FEMTO LDV Z8 in myopia and astigmatic myopia during follow-up.
