Myopia Control

The goal of this retrospective case series is to demonstrate the effectivity of combination low-dose atropine therapy with peripheral defocus, double concentric circle design with a center distance soft contact lenses at controlling myopia progression over 1 year of treatment. Included in this series are 3 female children aged 8–10 years with progressing myopia averaging −4.37 ± 0.88 D at the beginning of treatment. Their average annual myopic progression during the 3 years prior to therapy was 1.12 ± 0.75 D. They had not attempted any myopia control treatments prior to this therapy. The children were treated with a combination of 0.01% atropine therapy with spherical peripheral defocus daily replacement soft lenses MiSight<sup>®</sup> 1 day (Cooper Vision, Phoenix, AZ, USA). They underwent cycloplegic refraction, and a slit-lamp evaluation every 6 months which confirmed no adverse reactions or staining was present. Each of the 3 children exhibited an average of 0.25 ± 0.25 D of myopia progression at the end of 1 year of treatment. To the best of the authors’ knowledge, this is the first published study exhibiting that combining low-dose atropine and peripheral defocus soft contact lenses is effective at controlling children’s moderate to severe myopia progression during 1 year of therapy.

Myopia Control

Purpose. The prevalence of myopia is increasing worldwide and its long-term effects can have major impacts on eye health. Paediatric onset of myopia leads to a higher risk for developing high levels of myopia in adulthood. Slowing down or stopping myopia progression is an important task for the future. Material and Methods. Based on a literature review, the latest developments in the field of myopia control for children were summarized. The current study situation for orthokeratology, soft contact lenses, atropine therapy and spectacle lenses for the management of myopia is discussed in detail. Results. Results on the safety and effectiveness of orthokeratology and modified soft contact lenses are exceedingly consistent. Soft multifocal contact lenses, as well as newer spectacle lenses, recently received regulatory approval for myopia control. Studies on the administration of atropine recommend a dosage of 0.01 - 0.05 %. All methods slow down myopia progression and decrease axial length growth of the eye. Side effects, adverse events or discontinuation of treatment only occur in the rarest of cases. Orthokeratology and atropine continue to deliver the best results. Conclusion. From today’s perspective, carrying out myopia control can be recommended with great certainty. The choice of method depends on the individual requirements of each patient, with all methods offering success in reducing myopia progression. In the future, even more advanced contact lens geometries, more precise atropine dosages or improved optics of spectacle lenses will further increase the success of the treatment. Keywords.

The use of contact lenses for correcting refraction, suppressing myopia progression, and cosmetic purposes is increasing steadily. Contact lenses have various effects on the corneal surface and corneal infection can occur following obstruction of tear flow, micro-damage to corneal epithelial cells, corneal hypoxia, changes in corneal immunity, and exposure to contaminants. When a patient who used to wear contact lenses presents with keratitis, it is important to distinguish whether it is an infection; if it is an infection, it is important to find the causative strain and promptly treat it appropriately. Since improper lens care is related to infection, appropriate patient education is necessary, and the risk of contact lens infection should be reduced through regular ophthalmic examinations.

BACKGROUND Hyperopia occurs due to insufficient ocular growth and a failure to emmetropize in childhood. In anisohyperopia, it is unclear why one eye may remain hyperopic while the fellow eye grows toward an emmetropic state. Animal studies have shown that manipulating peripheral defocus through optical means while simultaneously providing correct axial focus can either discourage or encourage axial eye growth to effectively treat myopia or hyperopia, respectively. Myopia progression and axial eye growth can be significantly reduced in children and adolescents through the use of multifocal contact lenses. These contact lenses correct distance central myopia while simultaneously imposing relative peripheral myopic defocus. The effect of correcting distance central hyperopia while simultaneously imposing relative peripheral hyperopic defocus is yet to be elucidated in humans. OBJECTIVE The objective of our study is to understand the natural progression of axial eye growth and refractive error in hyperopes and anisohyperopes and to establish whether axial eye growth and refractive error can be modified using multifocal contact lenses in hyperopes and anisohyperopes. METHODS There are 3 elements to the program of research. First, the natural progression of axial eye growth and refractive error will be measured in spectacle-wearing hyperopic and anisohyperopic subjects aged between 5 and <20 years. In other words, the natural growth of the eye will be followed without any intervention. Second, as a paired-eye control study, anisohyperopes aged between 8 and <16 years will be fitted with a center-near multifocal design contact lens in their more hyperopic eye and a single-vision contact lens in the fellow eye if required. The progression of axial eye growth and refractive error will be measured and compared. Third, subjects aged between 8 and <16 years with similar levels of hyperopia in each eye will be fitted with center-near multifocal design contact lenses in each eye; the progression of axial eye growth and refractive error in these subjects will be measured and compared with those of subjects in the natural progression study. RESULTS Recruitment commenced on 6 June 2016 and was completed on 8 April 2017. We estimate the data collection to be completed by April 2020. CONCLUSIONS This trial will establish whether axial eye growth can be accelerated in children with hyperopia by imposing relative peripheral hyperopic defocus using center-near multifocal contact lenses.
