AIM: This study was conducted to evaluate the efficacy of Energie EyeRelaxä therapy to improve myopia in Chinese school children in 90 days.
METHODS: One hundred and eighty one Chinese school children aged 8 -11 years old with myopia between -0.25D and -3.25D were enrolled in a single-site, randomised, prospective and single masked study. All subjects were refracted thoroughly before the therapy began and prescribed with the latest prescription. Subjects in the treatment group were required to perform the Energie EyeRelaxä therapy twice a day for 90 days. A further 90-day follow-up was also carried out after the treatment was stopped. The primary outcome measures were refractive error and unaided visual acuity. In view of the hierarchical data structure, multivariate generalised linear latent and mixed models (GLLAMM) were applied to perform the analysis. Data were analysed with Stata 10.0 (Stata Corp, Texas, USA) and all statistical tests were conducted at 5% level of significance after correcting for gender, age, myopia, baseline refractive error and visual acuity.
RESULTS: Altogether, 93 subjects (51.4%) were randomised to receive Energie EyeRelaxä therapy. There was no significant difference in baseline characteristics between the Energie EyeRelaxä therapy and control groups. The right and left eye refractive error of the therapy group was reduced from -1.53 ± 0.77D at baseline to -0.73 ± 0.72D at 90 days and from -1.52 ± 0.81D at baseline to -0.70 ± 0.70D at 90 days respectively, and remained insignificant after the treatment was stopped. On the other hand, the control group’s right and left eye refractive error deteriorated from -1.56 ± 0.74D at baseline to –1.66 ± 0.77D at 90 days and further to -1.71 ± 0.77D at 180 days and from -1.50 ± 0.82D at baseline to –1.57 ± 0.84D at 90 days and further to -1.63 ± 0.84D at 180 days respectively. A similar result was observed in unaided visual acuity.
CONCLUSION: There is evidence suggesting that Energie EyeRelaxä therapy is effective in improving and maintaining myopia in myopic Chinese school children. Further investigations in other visual functions need to be conducted to support the use of Energie EyeRelaxä therapy.
