*Vertical heterophoria possibly caused by prism dissociation due to the presence of induced optical prism is a relevant factor for practitioners to consider when fitting toric contact lenses for monocular astigmats or those requiring a mix of toric soft contact lens designs e.g., mixed prescriptions.3,4 Clinical studies have not been done to fully characterize the clinical effects of differences in base down prism among different contact lenses
†Traditional prism and peri-ballast lens designs have a thicker area below lower eyelid than ACUVUE® Brand Contact Lenses for ASTIGMATISM that can cause interaction and may cause unwanted rotation due to lateral movement of the lower lid during blinks.
