Make sure the "Background copy" layer is selected and use the threshold tool to isolate the high contrast areas of the photo.

Right click >> Filters >> Blur >> Gaussian blur
Open the layer dialog box <ctl-l>, and change the layers mode from "Normal" to "Screen." Then use the "Opacity" slider bar to adjust the transparency of the top layer.
Select the background layer in and desaturate it. Right click >> Tools >> Color tools >> Hue-Saturation.
If you like, before desaturating the image, use the lasso tool to select the iris, and then invert the selection. Right click >> Select invert, and then desaturate. Everything will be desaturated EXCEPT the iris.
