Eyes

Hi,

   I'm trying to create realistic eyes for my human models. 
   
   I have viewed all the tutorials I could find in this forum and on the web. 
   
   The ones I found were for older versions of Zbrush and since the interface has changed the are difficult to follow. 
   
   I'm using Zbrush 3.1 on Vista.
   
   I can't seem to figure out how to create the iris part of the eye. The first image is an eye I made. I noticed in older tutorials that a noise material was used but I can't find a way to accomplish this. Also, using multi colors to define how the iris should be represented.
 
 If you look at the second image, this sample is what I would like to reproduce in Zbrush 3.1, or close to it.
   
   Help please,
   
   Marc
