Johnson & Johnson Vision is committed to changing the trajectory of myopia by shaping the standard of care. Our commitment is to lead by science and to generate evidence that can help practitioners provide the best patient care through improved technology and a portfolio of treatments.
Johnson & Johnson had a strong presence at the Association for Research in Vision and Ophthalmology (ARVO) 2022 meeting held recently in Denver, Colorado, with fifteen presentations. A number of our experts presented exciting new research at this meeting, some of which was selected by the ARVO committee as a hot topic and recognized by Review of Myopia Management as among the most “noteworthy myopia-related posters and papers.”
The ARVO meeting is the largest face-to-face global vision and ophthalmology meeting and typically attracts up to 10,000 attendees from all over the world from the leading research and medical institutions representing all fields of vision research, ophthalmology, and optometry. It is a place for sharing cutting-edge vision research and supporting collaboration.
Below we summarize some of the most exciting research coming out of Johnson & Johnson in myopia presented at the ARVO 2022 meeting.

With increasing use of axial length to monitor myopia progression, the ratio of refractive error (RE) change to axial elongation (AE) has important clinical implications. We conducted a systematic review and meta-analysis, identifying 67 applicable studies used to create a weighted multivariable mixed model of the ratio for untreated myopic children. The overall weighted mean ratio was 2.04 [95% CI: 1.96, 2.12] D/mm, and neither age nor race were significant covariates. This sets a benchmark for clinical expectations in myopic children and is lower than had been assumed, which may be a result of lens compensation observed in younger children or a decreased ratio, anticipated from optical calculations, in longer eyes of older children. Interpretation should consider limitations of using aggregated rather than individual subject data.
Design Concepts for a Myopia Control Soft Contact Lens

This is the first optical characterization of vision compromise versus myopia control efficacy with dual focus lenses to our knowledge. Through an extensive research program characterizing efficacy and visual quality with myopia control soft contact lenses, we learned that efficacy is related to the local power in the treatment zone rather than coaxial focal power and that the optical method by which treatment is delivered can have major impact on vision quality. Efficacy of typical soft contact lenses for controlling progression of nearsightedness is limited because adding plus power leads to vision compromise. We describe the basis of this effect and a novel method of getting around this problem so that the amount of plus power added is no longer limited by the impact on vision.
Final Level of Myopia versus Age of Onset: Effect of Race and Age at Final Refraction

By systematic review of nine studies, we observed that the final level of myopia can be estimated reasonably well according to the age of myopia onset. Delaying onset by one year in a young Asian subject can be equivalent to some three years of treatment in reducing final degree of myopia. As Benjamin Franklin said, “An ounce of prevention is worth a pound of cure.”
Influence of Age and Race on Axial Elongation in Myopic Children

With increasing interest in slowing myopia progression, and the importance of axial length measurement, normative data for axial elongation in myopic children should provide a valuable clinical reference. We conducted a weighted random effects meta-analysis to model axial elongation in myopic children with emphasis on the influence of age and race. Mean axial elongation decreases 15% per year as age increases (95%CI: 11.4%-18.5%, P <0.0001) and is 28% greater in Asian children (95%CI: 7.6%-52.2%, P <0.01) compared to non-Asians. This analysis sets benchmark values and estimates of the spread of axial elongation for monitoring myopia progression and treatment efficacy.
The Role of Myopia in 2020 Uncorrectable Global Visual Impairment

Combining the age distribution of the global population in 2020 and the Holden et al. (2016) estimate of myopia prevalence of 33.9% with the distribution of myopia severity from Brennan et al. (2020) and cumulative risk of vision impairment, we calculated that 29% (32 million) of the global uncorrectable vision impairment is due to myopia and associated diseases such as glaucoma, cataract, retinal detachment, and myopic macular degeneration. In our 2020 model, each 1% increase in myopia prevalence results in an additional 1.2 million with vision impairment. Projecting for 2050, each 1% increase in myopia is predicted to be associated with 2.7 million increased vision impairment. Comprehensive eye care programs and services will likely be needed to reduce myopia prevalence and severity, as well as treat diseases associated with myopia to reduce vision impairment.

Accommodation of the eye in response to multifocality of a lens may affect the myopia control efficacy of the lens. A soft contact lens (SCL) with the RingBoost technology (RB) was designed to maximize myopia control effect without affecting normal accommodation of the eye. This randomized, controlled, double-masked study of 10 young adults examined the accommodative response under four target vergences of the RingBoost, dual-focus, and a center-distance multifocal soft contact lens versus a single-vision soft contact lens and spherical spectacle lens corrections. Four analytical methods that were either refraction- or wavefront-based were utilized to determine accommodative response. The study demonstrated that across all metrics, the RB lens had similar or better accommodative performance than single-vision corrections.

Multizone soft contact lenses (SCL) have been shown to be effective to control myopia progression in young eyes and is thought to be due to myopic defocus. This project investigated the myopic defocus introduced and how this varied as a function of lens geometry utilizing a novel analytical method. In the same study described above, “eye plus lens” defocus of 10 young adults was examined based on wavefront aberrations measured under natural pupils with a Shack-Hartmann aberrometer. Percentage of the pupil that contained myopic defocused light for each of the four soft contact lenses: single vision (SV), dual-focus (DF), center-distance multifocal (MF), and a new soft contact lens with the RingBoost technology (RB). The study showed that multizone lenses introduced significant amounts of myopic defocus at all target vergences. However, magnitude and proportion of myopic defocus was influenced by the lens zone geometry and changes in pupil sizes. The RB lens retained relatively higher levels of myopic defocus at near viewing.
