We are committed to a refractive surgical correction of presbyopia and exploring its postoperative visual acuity effect and coronal morphology in order to provide a reliable reference value for the clinical application of this technology. The correction technique applied in this paper has improved the phenomenon of insufficient distance vision and difficulty in adaptation after multifocal correction in the past, and is more suitable for patients with high requirements for distance vision. In the future, we will pay more attention to the comparative research of several different correction method and try to provide the best treatment plan for patients with presbyopia in different conditions.
