I researched this and this practice of removing melanin from the eyes isn't legal at all. It can actually cause blindness, inflammation, and other problems. Many members here have brown eyes, and even fewer Gods, if you look at the descriptions of their appearance, It doesn't seem like it's a problem...
If you want to make a change, try using contact lenses in a safely way because even that can cause some inflammation, so imagine a laser removing your melanin, your natural protection.
