I, too, have Hashimoto's Thyroiditis and I went in for a pre-op appt for the Lasik surgery and saw on the form the question about whether you have an autoimmune disorder, so I asked the ophthalmologist about it and she said Hashimoto's didn't concern them. Apparently it was other autoimmune disorders like lupus, rheumatoid arthritis, and diabetes that they were concerned with. I hope this helps.
