For the PAM, a lot of the study materials are the same as for Part II. For the disease part, I used Wills (using I think the first couple of chapters as an outline). I typed out a study guide of some of the major diseases and presentations and some of what I thought was most important to know about them (including treatments). I also referred to photos online and in textbooks (Mass Eye is good to have on hand too...I didn't have the newest version of Wills yet with photos).
For the refractive conditions part, I referred back to my Part II study materials. Know the problems you can have with contact lenses and what they look like. And how to troubleshoot problems with fitting.
If your exam is anything like mine, there will be a few weird, seemingly "out there" questions. Don't panic, that's just how it is. It was also frustrating how many of the "biggies" that I thought for sure would be on there...weren't. I thought I had my butt handed to me on that test, but it all turned out quite well.
For the skills exam, you'll mostly want to study the outline until you could recite it in your sleep (especially the case history). Practice it over and over and over. Note that, on the contact lens part, you have to wash your hands a LOT.
It really will be fine.
