Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 30 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 11 manufacturers reported payments, led by Amgen at 31.5% of the total.
Across 30 payments — averaging $81.97 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Amgen$775
- Alcon$462
- Merz Pharmaceuticals, LLC$274
- Alcon Research LLC$215
- Biotissue Holdings Inc.$199
- Glaukos Corporation$157
- plus $376 from 5 others
Across 16 payments — averaging $142.82 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

General payments by program year
Who reported the general payments

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.

How this compares
Too few ophthalmic plastic and reconstructive surgery providers in North Carolinato place this figure against a meaningful peer group, so we don't.
Medicare billing
What this is not: this is the amount Original Medicare Part B allowed for services this provider billed in 2024. It is not their income. It excludes Medicare Advantage — now more than half of all Medicare enrollment — along with Medicaid and all commercial insurance, and it is gross practice revenue before staff, rent, supplies and malpractice premiums. CMS also suppresses any figure covering ten or fewer patients, so low-volume providers appear smaller than they are.
