Comparison of visual performance between a single and a dual-focus contact lens for the control of myopic progression

Myopia is a globally widespread ametropia. This has motivated the development of approaches to slow myopic progression, including the use of specific dual-focus contact lenses for myopia control. In this study, the visual performance of a dual focus contact lens (MiSightTM) and a single vision contact lens (Bausch & Lomb Ultra) was compared. To this aim, 25 myopic subjects were recruited (Sp from −0.50 D to −6.00 D, with max astigmatism of 1.00 CD). During the visit, the monocular and binocular visual acuity without correction was recorded, and the total topoaberrometry was performed. Subsequently, for each subject, monocular and binocular low-contrast visual acuity and high-contrast visual acuity was addressed with both type of lens. Visual quality was objectively evaluated by performing total ocular aberrometry. The results allow evaluating the effect of dual focus contact lens on vision.
