A solution for non spherical eyes thats what i started out to achieve but as i progressed i added a lot of elements for example there are 3 types of eyes in this tool that cover most of the workflows you may use in production and here are some of the features inside:
3-Iris and Pupil Control
4-Iris Rounder ( This makes the iris always round no matter how you stretch)
5-1 Click Mirroring
6-Connection with the head Rig

The tool is in its first release and will continue to develop it , i hope you see this tool as useful.
