I find the problem! The problem was that I wasn't using any default replacement eyes.
I usually use Shady Default Multicolor Eyes , but I deleted them a few days ago for change them for others default eyes , and then I deleted that default eyes , and I forgot to put the Shady Default Multicolor Eyes again.
So the "Under the original iris is formed a more big iris of solid color ..." were the original default eyes ._.
Well , this is already solved (anyway it's very strange -.-') ...
Now I have another question xD
The sclera of this eyes is different in my game ...
Lochie's Sclera (Above) and Lushness' Sclera (Below)
Why is different? I love the Lochie's Sclera
