Patients: Why I feel dry eye after cataract surgery or glaucoma surgery?

Patients always complain that my eyes feel very dry after my cataract extraction. Glaucoma patents complain too. The reasons are:

1. Surgery factor. The corneal incision access would cut off the nerve more or less. The cornea would lost nerve support and reflex, at last lead to less tears secretion.

2. Eye drops. The most of eye drops contain antiseptic substance (preservation AT, sofzia and BAK). That would cause the corneal epithelial cells damaged. And you will feel uncomfortable.

3. Enviromental factors. Your life habits, air conditioning and so on.

The only solution is to use artificial tears consecutively to substitute your natural tears.
