*Kruskal–Wallis test comparing the difference among three groups
☨ Fisher’s test comparing the number of eyes showing improved BSCVA between in ALI group and PBK group or FED group
☨☨ Fisher’s test comparing the number of eyes showing postoperative BSCVA >20/40 between in ALI group and PBK group or FED group
