Binocular Vision Alternations and fMRI Activation After ICL Implantation for High Myopia

Sex: All

Ages: 18 Years – 35 Years

Healthy volunteers: 1

Enrollment: 50

Sponsor: Zhongshan Ophthalmic Center, Sun Yat-sen University

Summary

Implantable collamer lens (ICL) is one of the most effective operation for high myopia. Due to refractive correction changed, and prism effect of the spectacle removed, in the early stage after ICL implantation, binocular function might be dysfunction, leading to asthenopia, blurred vision, double vision and so on. This study will recruit the high myopia subjects that scheduled for ICL implantation, purpose to investigate the binocular vision alternations and brain activation that impacted by ICL implantation.
