There is nothing wrong with laser surgery on the eye to correct weak vision
Question

                Is Laser surgery for correction of eyesight weakness forbidden so that one does not have to wear glasses.
Praise be to Allah.
    Doing laser surgery to correct weak vision is permissible. 
    And there is nothing wrong with doing it if it is done by an expert and it 
    is thought that the surgery will most likely be successful and will not 
    result in harm or complications that will make the situation worse than 
    before, because Islam forbids doing harm to oneself or to others, as the 
    Prophet  (peace and blessings of Allaah be upon him) said, “There should 
    be neither harming nor reciprocating harm.” Sharee’ah does not prevent the 
    Muslim from doing things that will benefit him and enhance his physical 
    faculties using permissible means. Laser surgery is not changing the 
    creation of Allaah. We ask Allaah to keep us, our religious commitment, our 
    health, our children and our wealth safe and sound.

     And Allaah knows best.
