Has Dagny Luong received payments from drug or device companies?

Yes. Drug and device makers reported $507,719 in general payments to Dagny Luong across 709 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 Dagny Luong 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

This record is dominated by consulting fees: $367,989 of the $507,719 with a category attached, or 72.5%. 25 manufacturers reported payments, led by Alcon at 55.3% of the total. 2025 is the largest year on record at $144,877, more than ten times the $1,019 reported in 2019. Among ophthalmology clinicians in CA 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.
