Progressive myopia is a condition of accelerated eye growth and a well-established risk factor for significant ocular pathology. Dual focus optics, which can be incorporated into both spectacle and contact lenses, have demonstrated effectiveness at slowing axial elongation and myopia progression in children and teens.
This study by Kollbaum et al. evaluated the ex vivo optical quality (via optical aberrometry) and on-eye visual performance (via a randomized double-masked clinical trial of 26 myopic children) of two commercially available disposable myopia control soft contact lenses: ACUVUE Abiliti 1-day (AB) and CooperVision MiSight 1-day (MS1d).
The AB lens design employs multiple add powers (including a small central zone of +10.00D) that includes non-coaxial annular zones. On the other hand, the MS1d is a coaxially designed dual-focus lens incorporating a central distance vision correcting zone with +2.00D annular adds.
Both lens designs were found to reduce image contrast but maintain the ability to resolve high spatial frequencies and support good visual acuity. However, the coaxial MS1d lens offers slightly superior optical performance. In instances of similar myopia control efficacy and adequate visual quality, the study suggests that clinical treatment choices (e.g. lens selection) may be based on patient-specific factors and preferences rather than myopia control characteristics.
Abstract
Optical Characterisation and Vision Quality Assessment of Two Myopia Control Contact Lenses
Purpose
This investigation examined the image and vision quality of two commercially available daily disposable myopia control soft contact lenses.
Methods
Wavefront errors were measured with an SHS Ophthalmic aberrometer for two myopia control soft contact lenses: a coaxially designed dual-focus lens (omafilcon A, CooperVision MiSight® 1 day, MS1d) and a design employing multiple add powers that included non-coaxial optics in annular add zones (senofilcon A, Johnson & Johnson Vision ACUVUE® Abiliti™ 1-Day, AB). Geometric optics ray tracing generated point-spread functions and wave optics were used to compare modulation transfer functions (MTFs) and simulated letter images. Twenty-six myopic children completed a randomised, non-dispensing, contralateral double-masked clinical trial. After 1 h of wear, right and left eye visual acuity (VA), subjective vision quality and lens preference (Likert) were assessed while viewing monocularly.
Results
The lens containing non-coaxial optics employed a small central zone with approximately +10.00 D of added power and two annular rings with a power gradient typical of non-coaxial optics. The coaxial design contained a centre zone with a distance correction and two annular zones with a fixed add power of approximately +2.00 D. MTFs and simulated images were better with small pupils, which was most noticeable with the coaxial design. Distance VA was -0.02 ± 0.04 with MS1d and 0.09 ± 0.08 with AB, p < 0.01. The majority of participants (77%) reported a preference for one lens; 54% preferred the MS1d and 23% preferred the AB lens.
Conclusions
Myopia control contact lenses employing coaxial or a mixture of coaxial and non-coaxial optics both reduced retinal image contrast but successfully imaged high spatial frequencies and provided high quality of vision. Image and vision quality were slightly superior in the lens employing coaxial optics alone.
