Usefulness of Implantation of Diffractive Multifocal Intraocular Lens in Eyes with Long Axial Lengths

Figure 6

Defocus curves. (a) Eyes were divided into axial length of 26 mm or longer (AL ≥ 26 group) and less than 26 mm (AL < 26 group). Bimodal curves are shown with two peaks at spherical equivalent addition of 0.0 D and D. Although a significant difference between two groups is observed at spherical equivalent addition of D, no significant differences were found at the other values. (b) Eyes in AL ≥ 26 group were further divided into 26 ≤ AL < 28 group and AL ≥ 28 group. Bimodal curves are also　observed. Significant differences are detected at additional spherical equivalent of 0.0, −1.5, −2.0, −2.5, and −3.0 D. -Whitney test.
