Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 14 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 7 manufacturers reported payments, led by Alcon at 25.2% of the total. Reporting peaked in 2021 at $117 and has fallen 52.8% since, to $55 in 2024. That places this record below the midpoint for optometrist clinicians in CT, where the typical reported total is $928.

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 |
|---|---|---|
| Alcon | 4 | $84 |
| AbbVie | 2 | $82 |
| Sun Pharmaceutical Industries Inc. | 3 | $63 |
| Bausch & Lomb, A Division Of Bausch Health US, LLC | 2 | $42 |
| Bausch & Lomb Americas Inc. | 1 | $26 |
| Coopervision Inc. | 1 | $19 |

How this compares
$333 in reported general payments places this provider in the 30th percentile of 574 optometrist providers in Connecticut.
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 |
|---|---|---|
| Cyclosporine | 13 | $7,366 |
| Latanoprost | 35 | $639 |
| Prednisolone Acetate | 12 | $341 |
| Neomycin-Polymyxin-DexamethNeomycin/Polymyxin B/Dexametha | 17 | $186 |
