Because eye nerves are 'autonomic'? You wouldn't likely 'feel' them.... Humm
Having gone thru cataract surgeries for both eyes? Those post-op eye drops make sense? As the sensory nerves that trigger eye tears and such wouldn't work post-surgery. Nerves can't signal the right responses if damaged...DUH
I guess, I'd rebut to the surgeon? Why do you eventually start-then-stop the 'artifical tears'?
BTW, I didn't have 'Lasic'? I had real knife and implant surgery, but for one eye I had laser later to remove some scar tissues... Did anti-biotic drops then as well.
The other problematic issue could be? HOW many nerves were disturbed and/or destroyed?
Either 'manual' or laser surgeries do pose a potential for a heap of 'nerve' damages. As there are a HEAP of nerves around the eyes.
How well, and fast they can grow? Well, Mrs D has proposed lots of research based approaches to help things along. Take into consideration that we are all different, and thus no one particular course of treatment is set in concrete.
