Visual Performance after a Unilateral or Bilateral Implantation of Enlarged Depth-of-Focus Intraocular Lens in Patients with Cataract: A Prospective Clinical Trial

Figure 3

Refractive outcome after the implantation of TECNIS® Symfony IOL. (a) Histogram showing postoperative spherical equivalent (SE) refraction measured by manifest refraction at 1, 4, and 12 weeks postoperatively. (b) Histogram showing the differences in SE between manifest refraction and automated refraction. (c) Histogram showing the percentage of eyes within ± 0.5 D and ± 1.0 D for the target refraction. (d) Histogram showing mean numerical error using SRK/T, Holladay 2, Haigis, Hoffer Q, Barrett Universal II, and Hill-RBF formulas. (e) Histogram showing mean absolute error using SRK/T, Holladay 2, Haigis, Hoffer Q, Barrett Universal II, and Hill-RBF formulas.
