NeuroVision's NVC™ vision correction is a non-invasive treatment based on visual stimulation and facilitation of neural connections responsible for vision. This treatment involves an internet-based computer generated visual training exercise regime using sets of patient-specific stimuli (Gabor patches) to sharpen contrast sensitivity function (CSF) and visual acuity (VA). The reported treatment successes were mainly in low myopes (−0.50DS to −1.50DS). This study is a pioneering effort to evaluate the efficacy of NeuroVision's treatment for unaided VA (UCVA) improvement in moderate myopes (−1.75DS to −3.00DS). 102 moderate myopes were given NeuroVision treatment, while another 35 subjects in a control group were given placebo treatment resembling the NeuroVision treatment in a superficial way. Each subject completed 40 sessions of treatment within 3 months. The end-of-treatment examination indicated a mean UCVA improvement of 0.17(+/−0.01) LogMAR for the treatment group and 0.10(+/−0.03) LogMAR for the placebo group. In addition, 58% of the treatment group and 42% of the control group have 0.2 LogMAR or more UCVA improvement in at least one eye. Nevertheless, the difference between the two percentages was not significant (P[[gt]]0.05, Fisher's Exact Test). However, after one year without further treatments, post-treatment examinations revealed strong retention of UCVA improvements in the treatment group but not in the control group; the treatment group still retained a mean UCVA improvement of 0.14(+/−0.01) LogMAR, while the mean control group improvements dipped to 0.05(+/−0.02) LogMAR. Moreover, 50% of the treatment group retained 0.2 LogMAR or more UCVA improvement in at least one eye after one year, significantly greater than the 24% observed in the control (P=0.01, Fisher's Exact Test). The retention results indicated that NeuroVision's NVC vision correction produced a stable one year post-treatment improvement in UCVA for moderate myopes.
