Many people like to use coloured contact lenses to change or enhance their natural eye colour.
Even after you have had laser eye surgery, you can still wear these types of lenses and they are available in a zero prescription power and therefore can just be used cosmetically.
You would probably want to refrain from wearing them for two to three months after undergoing LASIK (sooner after LASEK) just to make sure that your eyes have healed and have settled.
Always seek the advice from your ophthalmologist first though, as they are best placed to tell you when it is appropriate and safe to wear coloured contact lenses.
