An evaluation of four multifocal contact lenses in young monocular aphakic patients.

To evaluate the efficacy of multifocal contact lenses in the correction of presbyopic symptoms we fit six young monocular aphakic patients with four different bifocal contact lenses (ACC, Tangent Streak, VFL, and Constavu). Each patient had 20/20 uncorrected vision and normal accommodation in the other eye. We evaluated both subjective and objective parameters of comfort and vision for all four lenses. We found no significant overall performance advantage among the four lenses based on comfort, visual satisfaction, visual acuity, contrast sensitivity, or wear-related corneal complications.
