In order to use the lycoris model you will need to install this extension https://github.com/KohakuBlueleaf/a1111-sd-webui-lycoris and use it inside your prompt according to readme or with another extension - additional networks.
It can do both, the original style and the one with chromatic aberration, just use the tags accordingly.
You may want or not to remain original eye style, just prompt white eyes inside the positive or negative. If you still getting generations with this eyes even in the negative prompt just define eye color explicitly inside pos prompt like {red|yellow|blue|green} eyes or so.
