Has Tu Dinh received payments from drug or device companies?

Yes. Drug and device makers reported $28,232 in general payments to Tu Dinh across 195 transactions between 2019–2025. Most Open Payments records nationally are meals worth under $20; a reported payment is not evidence of wrongdoing.

Does a payment mean Tu Dinh did something wrong?

No. Federal law requires drug and device makers to report almost every transfer of value to a physician, including a $14 sandwich at a lunch presentation. Consulting fees, research funding and royalties to device inventors are ordinary, legal parts of medicine. This site reports what was disclosed; it makes no allegation.

Payments from drug & device makers

What this record shows

The money is spread across several categories — consulting fees (47.7%), food and beverage and speaking fees — rather than concentrated in one kind of arrangement. Johnson & Johnson Vision Care, Inc. accounts for 66.9% of it on its own, with 9 other manufacturers making up the rest. Reporting peaked in 2022 at $15,200 and has fallen 92.6% since, to $1,119 in 2025. Among optometrist clinicians in PA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
