It looks like they also somehow found the upper and lower lid curves. To truncate the circles, it looks like you just need to know when the circle goes above or below the lid curve. Do you have the lid curve?

no sir.... i dont have the lid curve.... i just got the circle around the iris....

The how can you possibly know where to stop the circle? If you don't know where to stop, then you can't stop it.
