I had several eye procedures done, and have used several types of drops and goops. If you have a ceiling fan or other fan in your bedroom, it will dry your eyes out, as well as running a heater or furnace. Ciba Vision puts out a product called, "GenTeal Lubricant Eye Gel" in a little tube. i pull my lower eyelid out, and squirt a little dab of it behind the eyelid. Your eye will feel a little gooey, but your bodyheat will melt it down. I have found that this gel keeps the eye lubricated all night, and works better than drops.
If your eyes feel like they are burning due to dust or other allergens, I would use Visine-A which has an antihistamine in it. You can also use Patanol, but it is prescription, and more expensive. I also suggest a sleep-mask to keep the breeze of the fans/furnace from drying out your eyes. In addition, if your eyes feel hot and dry, an icepack, cool pack, or wet washrag over the eyes will feel great.
Take care of your eyes. I learned the hard way; -on a windy day, a plastic nametag on a lanyard blew up into my face, striking me in the left eye, and cutting through both layers of my cornea. I endured 2 seperate eye procedures, as well as all sorts of eye pain and pressure, and wearing a bandage contact lens for 8 months. -Starkdog
