“…As seen in other studies of presbyopia 31 and myopia control 32 contact lenses, both visual acuity and contrast sensitivity were slightly degraded with the multifocal contact lenses used in this study. Decreased visual acuity and contrast sensitivity were also consistent with previous findings on young adults wearing multifocal lenses.…”

Purpose To determine the effect of multifocal contact lenses on accommodation and phoria in children. Methods This was a prospective, non-dispensing, randomized, crossover, single visit study. Myopic children with normal accommodation and binocularity and no history of myopia control treatment were enrolled and fitted with Coopervision Biofinity single vision (SV) and multifocal (MF, +2.50D center distance add) contact lenses. Accommodative responses (photorefraction) and phorias (Modified Thorington) were measured at 4 distances (>3m, 100cm, 40cm, 25cm). Secondary measures included high and low contrast logMAR acuity, accommodative amplitude and facility. Differences between contact lens designs were analyzed using repeated measures regression and paired t-tests. Results A total of 16 subjects, aged 10-15 years, completed the study. There was a small decrease in high (SV: -0.08, MF: +0.01) and low illumination (SV:-0.03, MF: +0.08) (both p<0.01) visual acuity, and contrast sensitivity (SV: 2.0, MF: 1.9 log units, p=0.015) with multifocals. Subjects were more exophoric at 40 cm (SV: -0.41, MF: -2.06 Δ) and 25cm (SV: -0.83, MF: -4.30 Δ) (both p<0.01). With multifocals, subjects had decreased accommodative responses at distance (SV: -0.04; MF: -0.37 D, p=0.02), 100 cm (SV: +0.37; MF: -0.35 D, p<0.01), 40 cm (SV: +1.82; MF: +0.62 D, p<0.01), and 25 cm (SV: +3.38; MF: +1.75 D, p<0.01). There were no significant differences in accommodative amplitude (p=0.66) or facility (p=0.54). Conclusions Children wearing multifocal contact lenses exhibited reduced accommodative responses and more exophoria at increasingly higher accommodative demands than with single vision contact lenses. This suggests that children may be relaxing their accommodation and using the positive addition or increased depth of focus from added spherical aberration of the multifocals. Further studies are needed to evaluate other lens designs, different amounts of positive addition and aberrations, and long-term adaptation to lenses.

“…Our findings on good distance HCVA and reduced visual quality ratings with the MiSight lens are in agreement with the study conducted by Kollbaum et al [19]. Similarly, a study by Papas et al assessed objective and subjective vision performance variables of multifocal contact lenses over a moderate adaptation period and found that subjective performance tests were more useful measures than visual acuity based tests [27].…”

“…Such lenses not only include the plethora of commercially available bi-and multifocal contact lenses but also novel lens designs, including the marketed myopia control contact lens MiSight, which features a large central distance zone surrounded by alternating concentric distant and near zones. Various commercial and novel multifocal contact lenses have been assessed for the capacity to retard myopia progression [13][14][15][16][17], however, few studies have assessed the visual performance of multifocal contact lenses in non-presbyopic myopic eyes [18][19][20]. The accumulated evidence from these studies indicates some degradation of visual performance is likely to occur when contact lenses with multiple refractive zones are worn.…”

“…31 Though the Biofinity multifocal lens utilized in this study is not a concentric ring design, a recent study by Kollbaum et al found that visual performance was the same with both a concentric ring multifocal (MiSight; CooperVision) and the Proclear Multifocal “D” lens, which is similar in design to the lens used in the present study. 55 This finding suggests that it is reasonable to expect that children would accommodate when wearing the Biofinity Multifocal “D” lens similar to the young adults in the present study. That being said, peripheral defocus at near should be measured in any study following children over time to confirm their accommodative state.…”

Purpose To describe peripheral defocus when myopic eyes are corrected with spherical and center-distance multifocal soft contact lenses while looking at distance and near. Methods Twenty-five young adults with spherical contact lens-corrected refractive error of −0.50 to −6.00 D participated. Refractive error of each participant’s right eye was measured while it wore a spherical soft contact lens (Biofinity) and again while it wore a center-distance multifocal soft contact lens with a +2.50-D add (Biofinity Multifocal "D"). Measurements were made centrally and along the horizontal meridian at ±20°, ±30°, and ±40° from the line of sight at distance and near (3.33-D demand). Results The mean (±SD) age and spherical equivalent refractive error were 23.8 ± 1.3 years and −3.62 ± 1.56 D, respectively. At distance, the multifocal contact lens resulted in significantly more myopic defocus than the spherical contact lens at the 40° and 30° locations on the nasal retina and at the 20° and 30° locations on the temporal retina (p<0.0001). When accommodating to a near target, peripheral defocus was more myopic with the multifocal lens than with the spherical lens (p<0.0001). When viewing the near target with the spherical lens, participants experienced foveal hyperopic defocus and peripheral hyperopic defocus at all but one peripheral location. While participants also experienced foveal hyperopic defocus with the multifocal when looking at near, peripheral defocus was minimal (not significantly different than zero) at several locations (i.e., peripheral emmetropia). Conclusions The center-distance multifocal lens created peripheral myopic defocus when looking at distance. When looking at near, the multifocal lens resulted in relatively more myopic (less hyperopic) peripheral defocus than the spherical lens. The defocus profiles experienced with the multifocal contact lens in this study make it a good candidate for studies seeking to examine the effect of peripheral myopic defocus on myopia progression in children.

Vision Performance With a Contact Lens Designed to Slow Myopia Progression

Abstract: Good acuity, similar to that attainable with typical MF lens correction, is attainable with a new contact lens designed to control myopia progression. However, like other contact lenses that contain multiple refractive zones, some decrease in visual performance may be experienced.
