Studies from Second Affiliated Hospital of Zhejiang University School of Medicine Further Understanding of Myopia (Effects of different orthokeratology lens designs on slowing axial length elongation in children with myopia).

A study conducted at the Second Affiliated Hospital of Zhejiang University School of Medicine aimed to compare the effects of different orthokeratology (ortho-k) lens designs on slowing the elongation of axial length (AL) in children with myopia. The study enrolled 654 subjects who were prescribed one of three specific brands of ortho-k lenses: CRT, Euclid, and Mouldway. The results showed that ortho-k lenses, particularly those using the vision shaping treatment (VST) design, were effective in slowing the progression of myopia. The study concluded that ortho-k lenses represent a practical strategy for mitigating the advancement of myopia. [Extracted from the article]
