FS-CRI group = femtosecond laser-assisted corneal relaxing incisions with implantable collamer lens implantation; TICL group = toric implantable collamer lens implantation; UDVA = uncorrected distance visual acuity; CDVA = corrected distance visual acuity.Cohen’s d is the standardized mean difference between two independent groups, calculated as mean difference divided by the pooled SD
