Really interesting. I had no idea. How fortunate that you've learned this!

There's a supplement that may be helpful, as it supports a healthy immune environment in the eyes. (Actually, it does this in all of our organs requiring significant moisture, especially our mouth and eyes. Genitals too, I'd guess.) It's lactoferrin, a glycoprotein that the body synthesizes, and it's produced at super high levels in mother's milk. I first learned about it when my husband was on a checkpoint inhibitor for his cancer and had developed very dry mouth and eyes, and his sense of taste became very distorted and at times disappeared. I posted the taste problem on the botanical/integrative medicine listserve I belong to, and a physician who works at a hospital in West Va said that standard treatment there for patients who had lost their sense of taste during chemo was 250 mg of lactoferrin (Jarrow) 3x/day. It restores taste for the large majority, and they were contemplating organizing a clinical trial.

So I got it. And gradually......he no longer needed his several-times-a-day eye drops, and no longer needed his saliva-like mouth drops. And the weird tastes disappeared. And the lost ones returned. I continued the lactoferrin, and I wouldn't be surprised if this played a role in his healing with amazing speed after his cataract surgeries. I began taking it too'just 2/day'before my cataract surgeries, and have continued. Our immune system needs support as we get older. And it's not just fighting bacteria and viruses and cancer, etc, but the immune environment in more local niches.

So you might want to consider this, and see if it makes a difference. I get mine at allstarhealth.com, which has great discounts.
