Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 95.8% of the total across 26 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 12 manufacturers reported payments, led by Alcon at 37.1% of the total. Reporting peaked in 2019 at $315 and has fallen 57.8% since, to $133 in 2023. That places this record below the midpoint for ophthalmology clinicians in NV, where the typical reported total is $1,540.
Across 26 payments — averaging $35.38 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.

- AmnioGraft$150
- AmnioGuard$150
- Wavelight Refractive Suite$133
- AcrySof IQ PanOptix$125
- KXL System$113

How this compares
$920 in reported general payments places this provider in the 40th percentile of 121 ophthalmology providers in Nevada.
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.
