The goal of this clinical trial is to learn about an innovative surgical technique for macular hole repair. This technique is for patients with high myopia using pars plana vitrectomy (PPV) combined with corneal flap transplantation. The main questions it aims to answer are: * Is the innovative surgical technique useful for patients? * Is the surgical technique safe for patients? Participants will: * Undergo PPV combined with corneal flap transplantation to cover the macular hole. * Maintain a prone position for 2 weeks postoperatively. * Be observed by visual acuity, slit lamp, optical coherence tomography (OCT) and fundus photography for 1 year after surgery.
