Proper centration of premium IOLs — diffractive multifocal, moderate to high toric, and aspheric — is critical to achieve the maximum optical performance and to avoid unnecessary symptoms of halos, glare and “waxy vision.” To understand and use the optical principles involved with these complaints, we must review the angles of the eye.In Figure 1, we see a cross-section of the eye from above illustrating that the foveola is temporal to the optical axis of the eye by a nominal 5.2°.
