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.

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.

Accommodation disorders in young people are more common than diagnosed. This review is based on the data of domestic and foreign literature and studies the effect of contact lenses of various designs on accommodation. Particular attention has been given to bifocal soft contact lenses as one of the recognized interventions for treating juvenile progressive myopia and their ability to slow axial elongation. Key words: accommodation, myopia control, bifocal contact lenses, orthokeratology.

PurposeTo determine if the spatial distribution of the relative corneal refractive power shift (RCRPS) explains the retardation of axial length (AL) elongation after treatment by either orthokeratology (OK) or multifocal soft contact lenses (MFCLs).MethodsChildren (8–14 years) were enrolled in the OK (n = 35) or MFCL (n = 36) groups. RCRPS maps were derived by computing the difference between baseline and 12-month corneal topography maps and then subtracting the apex values. Values at the same radius were averaged to obtain the RCRPS profile, from which four parameters were extracted: (1) Half_x and (2) Half_y, i.e., the x- and y-coordinates where each profile first reached the half peak; (3) Sum4 and (4) Sum7, i.e., the summation of powers within a corneal area of 4- and 7-mm diameters. Correlations between AL elongation and these parameters were analyzed by multiple linear regression.ResultsAL elongation in the OK group was significantly smaller than that in the MFCL group (p = 0.040). Half_x and Half_y were also smaller in the OK group than the MFCL group (p &lt; 0.001 each). Half_x was correlated with AL elongation in the OK group (p = 0.005), but not in the MFCL group (p = 0.600). In an analysis that combined eyes of both groups, Half_x was correlated with AL elongation (β = 0.161, p &lt; 0.001).ConclusionsThe OK-induced AL elongation and associated RCRPS Half_x were smaller than for the MFCL. Contact lenses that induce RCRPS closer to the corneal center may exert better myopia control.
