This study will evaluate the efficacy and safety of posterior scleral reinforcement on controlling myopia progression, including change in refraction, axial elongation as well as sight-threatening complications, in adults with high myopia. Half the adults will receive posterior scleral reinforcement, while the other half will receive no surgerical treatment.

Posterior scleral reinforcement (pPSR) is a procedure applied with autologous or biological material or synthetic materials reinforcing pole of the sclera after eyeball, in order to prevent or alleviate myopic development.
