Anisometropia occurring either as a result of physiological or acquired etiologies may present a challenge to the optometrist if the patient is presbyopic. Fortunately, many patients with anisometropic presbyopia are able to adapt to near induced hyperphoria. There are, however, several options available for the optical management of symptomatic patients with near induced hyperphoria. These include: displacement of the distance optical centers, setting the bifocal segment higher than usual, using a combination of these two, dissimilar bifocal segments, slab-off prism and contact lenses. This paper reviews clinical considerations as well as the available spectacle management options.
