monocular and binocular visual acuity
uncorrected distance visual acuity (UCVA), intermediate visual acuity, near visual acuity will be measured at 5m, 80cm and 40cm respectively. All visual acuity measurements will be conducted under photopic conditions (85 cd/m2) and at 100% contrast
3 months postoperatively
economic efficiency
economic efficiency was defined as the ratio of objective spectacle independence (UCVA better than 0.10 logMAR) and IOL price, then compare the economic efficiency among different groups.
