Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.5% of the total across 258 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 20 manufacturers, the largest accounting for just 18.5% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $1,431 and has fallen 93.9% since, to $87 in 2025. Among optometrist clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 258 payments — averaging $16.21 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.

Paid to pharmacies, not to this prescriber.
Companies that both paid and supply prescribed drugs
These companies both reported payments to this provider and make drugs the provider prescribed under Medicare Part D in 2024. For most specialties this overlap is expected — a cardiologist who is paid by a cardiology drugmaker also treats heart disease. It is shown so the reader can see it, not because it implies anything on its own.
| Company | Paid to this provider | Part D cost of their drugs |
|---|---|---|
| Bausch & Lomb Americas Inc.Xiidra, Miebo | $57 | $103,335100 claims |
| AbbVieLumigan, Restasis | $774 | $57,01684 claims |
| Aerie Pharmaceuticals, Inc.Rocklatan | $734 | $11,03232 claims |
Reading this fairly. The Part D column is what drug plans and patients paid pharmacies — this provider received none of it, and it reflects how many patients they treat and what those drugs cost. Against peers, this provider's reported payments sit in the 90th percentile of 6,778 optometrist providers in California.
