Somewhere around 1989, I got a rusty sliver of metal in my left eye. It was blown in by a harsh wind, and when I blinked, the movement of my eyelid forced it into the cornea.
It cut through layers 1 and 2, and rested against layer 3. ( Out of 5 ). The eye dr. informed me that he would have to use a burr and remove the rusty bit, along with a tiny smidgen of the surrounding cornea. No idea going in if the resulting scar tissue would impair my vision in any way or not.
The next day I, the professional cameraman who lives by his eyes, sat down, rested his chin in “that amazing bizarre eye dr. device thingy”, and was told to SIT VERY STILL AND NOT BLINK. Yes, sir. I watched him burr the bit out.
No vision loss, but the damage destroyed the integrity of my cornea. Ever since then, until perhaps a year or two ago, I’ve had R.C.O. He gave me similar goopy stuff to drizzle in, so that the cornea was protected and lubricated.
Apparently there is a lovely vacuum that exists within the layers of the cornea, and doing that kind of damage wrecked it. I believed him at the time, but now with the advent of Lasik surgery, I dunno about the vaccum part.
I do know that in serious dry air or air conditioned air, if I were not careful in opening my eyes in the morning I’d re-rupture. And oh god does that hurt.
If Muro 128 is pricey, ask another eye dr. to recomment a suitable cheap replacement. Really, all I needed was these tiny tubes of what was essentially highly sterilized petrolium jelly. ( Vaseline ). Not under that name, but that was what was IN it.
IANAD, so please talk to your eye dr. before switching. For years, those little blue and white tubes cost me…what, about $ 5.00 per and lasted months.
Eventually I think the cornea does replace some damaged cells, because although it is now muscle memory that makes me wake up with the left eye held shut, I have not felt much more than a tiny tug- and only on a VERY dry morning with either heat or a.c. pumping- in quite a few years.
Best of luck, email me if you wish for more detailed conversation.
