Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 21 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 8 manufacturers, the largest accounting for just 20.5% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $173 and has fallen 73.6% since, to $46 in 2025. That places this record below the midpoint for optometrist clinicians in CO, where the typical reported total is $596.
Across 21 payments — averaging $26.96 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
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| Rxsight Inc | 1 | $116 |
| Bausch & Lomb Americas Inc. | 5 | $106 |
| Bausch & Lomb, A Division Of Bausch Health US, LLC | 4 | $98 |
| Alcon | 4 | $97 |
| Johnson & Johnson Vision Care, Inc. | 2 | $47 |
| Astellas Pharma US Inc | 2 | $44 |
| Nobel Biocare USA | 2 | $33 |
| Glaukos Corporation | 1 | $25 |
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
$566 in reported general payments places this provider in the 45th percentile of 1,025 optometrist providers in Colorado.
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.
Most prescribed under Part D
| Drug | Claims | Cost to plans & patients |
|---|---|---|
| Latanoprost | 80 | $696 |
| Brimonidine Tartrate | 31 | $258 |
| Neomycin-Polymyxin-DexamethNeomycin/Polymyxin B/Dexametha | 11 | $176 |
| Timolol Maleate | 12 | $134 |
