Deciding the refractive target and IOL for cataract surgery is a daunting task for both the surgeon and patient. The first two questions that must be answered are: Do you mind wearing glasses for intermediate and near tasks, and would the presence of halos and glare be acceptable in exchange for reducing your dependence on glasses?
If the patient does not mind wearing reading glasses, then providing the best distance vision in each eye is the goal. Using aspheric IOLs to reduce spherical aberration and produce the best retinal image quality, eliminating astigmatism and achieving a spherical equivalent prediction error near zero will lead to a high percentage of satisfied patients in this group.
