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

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.
