It's very simple...

Do this for both eyes. Dblclk the zTrans dial (for both eyes) and input the value of your choosing for both min and max limits. Save the cr2 to your library.

Open the cr2 in your favorite cr2 editor and set the "forceLimits" flag for "translateZ ztran" channel to "1" in actors "leftEye" and "rightEye". This will lock zTrans to the value you chose, regardless of what pose is applied and whether or not you have limits turned on (the "1" forces it, "4" is used to follow). This will also prevent the axis for x (up-down) and y (side-side) from being offset, like would happen with a morph or magnet... in addition to not consuming drive space with an additional mesh [eyes translated].

You really don't even need to do anything in Poser, you could just open the cr2 that you want as the base of your new figure [in an editor] and set the values there. All three are right next to each other.
