Just wanted to add in a word of advice about coloured contact lenses.
Coloured contact lenses contain extra pigment to give the contact lens its colour. Depending on the manufacturer or brand of these contact lenses, the application process of this pigment on the contact lens might not be done well or properly.
This is especially so if the coloured contact lens is not FDA-approved or have not been through any stringent regulations or certification. It is much too easy to buy coloured contact lenses online these days, however it is uncertain whether these contact lenses have been tested for any side effects prior. So do be careful about where you obtain your coloured contact lenses.
I have seen personally cases of coloured contact lenses causing cornea abrasions (because the pigment on the contact lens is applied roughly and its uneven surface may scratch the cornea). I'm sure you would not want to suffer a cornea abrasion after your refractive surgery procedure. In addition, the pigment from the coloured contact lenses may come out to stain the cornea (such cases have been described).
Although I would not be able to say for certain which brands are trustworthy, my advice would be : If you must wear coloured contact lenses, try to ensure that your coloured contact lenses are FDA-approved at the very least.
Hope that helps!
