boric acid why? I'm sure he's talking about a very dilute concentration of this, but still, why not just put some vinagar in the eye, and add some salt. Now done with the sarcasm, and I know it's not you or your friend's fault, but now you know.
If anything at this time, you'll want to use simple saline drops that you use with contact lenses.
See www.arav.com and previous threads for the multitude of ways of finding a herp vet in your area. As reptiles are still somewhat of a specialty pet, and depending how remote you are, you should be prepared to drive a bit, perhaps even take a day off work. All in all, any vet of sane mind and a willingness to learn, with an appreciation of reptiles, and a humbleness that they don't know it all, will be better off than no vet at all. They have access to textbooks and veterinary online subscriptions to tap the minds of the world's finest reptile vets.
Good luck with your lizard.

ps, as an aside, your first post mentioned a 60W in a 55 gallon. In most areas of North America at this time of year, that won't get it hot enough. You'll need a thermometer to be sure, there's really no way around it.
