First of all, I'm so glad your retina is healing nicely. That can be devastating if it doesn't...
And yes, they've come a long way with contacts! I really hope you wear them easily, but if dry eyes are still a problem here are some things I did...
I had allergies and dry eyes to the point of having to quit wearing even the new and improved contacts. However, I found that a lot of my dry eye issues had to do with diet, and when I quit eating these things my dry eyes got better. For me it was wheat and anything with vinegar (fermentation/yeast), along with alcohol (yeast). So, just in case you want to give this a try...I also found some really great naturopathic eye drops that helped a lot.
One last thing I tried was a pair of soft goggles made for dry eyes...you sleep in them, and there's a little sponge you moisten, and basically they keep your eyes from drying out when you sleep...they were comfortable and worked really well.
Here's the website I found them on...they're called TranquilEyes...
