| Research Abstract |
We clarified that orthokeratology can suppress myopic progression in childhood myopia. Our results confirmed that axial elongation was significantly smaller in the orthokeratology group than in the spectacle control group. The inhibitory effect was most noticeable over the first year of orthokeratology treatment and decreased with time. The details of these results were summarized in the following two articles. (Kakita T, Hiraoka T, Oshika T. Influence of overnight orthokeratology on axial elongation in childhood myopia. Invest Ophthalmol Vis Sci. 2011 ; 52:2170-4), (Hiraoka T, Kakita T, Okamoto F, Takahashi H, Oshika T. Long-term effect of overnight orthokeratology on axial length elongation in childhood myopia : a 5-year follow-up study. Invest Ophthalmol Vis Sci. 2012 ; Epub ahead of print).
