结局指标
主要结局
Best Corrected Visual Acuity
时间窗: 3 months postoperatively
The BCVA was measured by the same optometrist at each visit
Tear Breakup Time
时间窗: 3 months postoperatively
Tear Breakup Time was performed to assess tear film stability
Uncorrected distance visual acuity
时间窗: 3 months postoperatively
The UCVA was measured by the same optometrist at each visit
Intraocular pressure
时间窗: 3 months postoperatively
Intraocular pressure measured using non-contact tonometer
Glasses usage frequency
时间窗: 3 months postoperatively
The frequency of long / medium / short distance use of corrective glasses was scored as 0%, 25%, 50%, 75% and 100%
Optical visual quality questionnaire
时间窗: 3 months postoperatively
Glare, halos, starburst and other visual quality problems were graded as mild（1 score), moderate（2 score) and severe（3 score)
Endothelial cell density
时间窗: 1 month postoperatively
Endothelial cell density was measured by specular microscopy
Contrast sensitivity
时间窗: 1 month postoperatively
The contrast sensitivity was recorded in dark environment, glare dark environment, light environment, glare light environment
Stereoscopic vision
时间窗: 1 month postoperatively
The binocular diopter was not corrected. The stereopsis test card was used to record the arc seconds of random points, animals and circles
Defocusing curve
时间窗: 1 month postoperatively
From +2.00d to -4.00d, 13 different diopter states were obtained by decreasing the spherical lens degree of +0.50d, and the defocus curve was formed
Visual satisfaction
时间窗: 3 months postoperatively
The visual acuity satisfaction of distance / middle / near distance was scored from 0 (totally dissatisfied) to 10 (totally satisfied)
