Effect of incision on visual outcomes after implantation of a trifocal diffractive IOL

To evaluate 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. This prospective study enrolled patients randomly assigned to different groups. According to...

Description
Summary:To evaluate 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. This prospective study enrolled patients randomly assigned to different groups. According to preoperative corneal astigmatism, 101 eyes of 77 patients were assigned into group A (0 ~ 0.50 D) or A (0.51 ~ 1.00 D) with a corneal steep-axis incision or group B (0 ~ 0.50 D) or B (0.51 ~ 1.00 D) with a 135° incision. Visual acuity, corneal astigmatism and corneal higher-order aberrations (HOAs) were followed-up for 3 months. Corneal astigmatism in group A significantly decreased 3 months after surgery (P
