Primary

Measure	Time frame
Uncorrected visual acuity (UCVA). Timepoint: one day preoperatively and the first day, third day, at the end of the first. Method of measurement: visual acuity without correction based on snellen chart at 6 meter.;Best corrected visual acuity (BCVA). Timepoint: one day preoperatively and the first day, third day, at the end of the first. Method of measurement: visual acuity based on snellen chart at 6 meter,after correction.(based on subjective refraction.;Central corneal thickness (CCT). Timepoint: one day preoperatively and the first day, third day, at the end of the first. Method of measurement: central corneal thickness (micron) based on Pachymetry.;Spherical equivalent (SE). Timepoint: one day preoperatively and the first day, third day, at the end of the first. Method of measurement: spherical power (diopter) based on objective refraction.: S.E =Sphere+Cylinder/2.;Astigmatism. Timepoint: one day preoperatively and the first day, third day, at the end of the first. Method of measurement: cylinder power based on objective refraction.	—
