I have recently decided to have surgery to remove spectacles as I'm 20 year old and my minus numbers are stable since 2 years and the thing is I came to know that during this surgery my cornea is displaced temporarily and then at the end of surgery it is positioned at its place. My question is that once the cornea is cut and displaced from eyes, can it be fixed as it was before surgery or in future maybe due any accident or anything it might displace again?? That is what I fear of!!..
