Effects of multifocal soft contact lenses used to slow myopia progression on quality of vision in young adults

Abstract

ABSTRACT.Purpose: To assess the effects of multifocal soft contact lenses (MF SCLs) used for myopia control on visual acuity (VA) and subjective quality of vision. Methods: Twenty-four young adult myopes had baseline high and low-contrast VAs and refractions measured and quality of vision assessed by the Quality of Vision (QoV) questionnaire with single vision SCLs. Additional VA and QoV questionnaire data were collected immediately after subjects were fitted with Proclear MF SCLs and again after a 2-week adaptation period of daily lens wear. Data were collected for two MF SCL designs, incorporating +1.50 and +3.00 D peripheral near additions, with a week washout period allowed between the two lens trials. Results: High-and low-contrast VAs were initially reduced with both MF SCL designs, but subsequently improved to be not significantly reduced in the case of high-contrast VA by the end of the 2-week adaptation period. The quality of vision was also reduced, more so with the +3.00 D MF SCL. Quality of Vision (QoV) scores describing frequency, severity and bothersome nature of visual symptoms indicated symptoms worsening rather than resolving over the 2-week period, particularly so with the +3.00 D MF SCL. Conclusion: Low and high add MF SCLs adversely affected vision on initial insertion, with sustained effects on low-contrast VA and QoV scores but not high-contrast VA. Thus, high-contrast VA is not a suitable surrogate for quality of vision. In prescribing MF SCLs for myopia control, clinicians should educate patients about these effects on vision.

Light disturbance with multifocal contact lens and monovision for presbyopia

“…The QoV questionnaire did not show (any) significant change in QoV score from baseline for either modality of the lens and there were no differences between monovision and multifocal lenses. Recently, Kang et al [43] assessed the effects of soft multifocal contact lens used for myopia control (Proclear multifocal, CooperVision, with addition power +1.50 and +3.00) on subjective quality of vision compared to a single vision Proclear spherical contact lens. They reported a significant increase in QoV scores with Proclear multifocal with symptoms worsen over the 2-week wearing period, particularly with the multifocal with +3.00 Add.…”

IMI – Clinical Management Guidelines Report

“…194 Further discussion of this can be found in Section 8b. As currently available MFSCLs, particularly lenses with higher add powers, can significantly reduce quality of vision, 195,196 it is essential that visual acuity and quality of vision are monitored. In cases where the patient experiences significant reduction in visual acuity and/or subjective quality of vision with the selected MFSCL, an over-refraction should be conducted and incorporated into the lens power.…”

Comparison of short‐term light disturbance, optical and visual performance outcomes between a myopia control contact lens and a single‐vision contact lens

“…In accordance with the present study, a number of authors found an increase in subjective symptoms with different multifocal contact lenses. 24,26,31 Fedtke et al 39 reported that decentred multifocal contact lenses with higher power variations produce lower subjective ratings. Sha et al 25 found that two prototype lenses were tolerated better by non-presbyopic myopes than the DF design lens used in the present study and another commercially available, centre-distance multifocal contact lens.…”
