Xue S, et al. - Authors assessed the visual acuity, corneal astigmatism and corneal higher-order aberrations (HOAs) after implantation of trifocal diffractive IOLs operated with either a corneal steep-axis incision or 135° incision. Reduced corneal astigmatism was exhibited by patients with preoperative corneal astigmatism of 0.51 D to 1.00 D after a corneal steep-axis incision. These patients achieved better uncorrected intermediate visual acuity (UIVA) and early postoperative uncorrected distance visual acuity (UDVA)/uncorrected near visual acuity (UNVA).
