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

Table 2

Postoperative refractive data. (A) Patients were stratified into axial length of 26 or above (AL ≥ 26 group) and below 26 mm (AL < 26 group). (B) Eyes in AL ≥ 26 group were further divided into 26 ≤ AL < 28 group and AL ≥ 28 group.
