I have just submitted my dissertation (St. Andrews University, Scotland) on soft focus lenses. You might inquire of folks present at APIS 2005 or the English APIS 2003 who heard me speak on the subject; I can PM you my viva if you are interested.
Jeremy- I have a nearly complete run of the NPS Journal and Newsletters- there are a lot! However, there may be some copyright issues. PM me if you're still game and we can discuss the nitty-gritty.
