Primary outcome measure(s)
Defocus curve — Three months after operation On the basis of BCDVA, add +2.5\~-5.0D spherical lenses (decreasing at intervals of 0.5D) before the patient's operation, record the logMAR vision of the patient at each added spherical lens degree, and draw the average Defocus Curve with the added spherical lens degree as the abscissa and the average vision of each corresponding degree as the ordinate.
Far, middle and near vision — Three months after operation The naked eye vision was measured at 5m, 70cm and 40cm respectively.
