Posterior Scleral Reinforcement（PSR） is the only surgical method that can delay the the development of high myopia. However, The surgical method is restricted by the material source limitation and macular ischemia in the eye after reinforcement. The investigators have designed a new posterior scleral fixation system，Its basic material is medical silicone，The product is designed to solve the problem of material source limitation and macular ischemia in the eye after reinforcement.
The purpose of this study is to assess the primary safety and efficacy of High Myopic Posterior Scleral Fixation System in the treatment of macular schisis caused by high myopia.
