Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.2% of the total across 29 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Alcon accounts for 66.2% of it on its own, with 8 other manufacturers making up the rest. Reporting peaked in 2019 at $387 and has fallen 91.0% since, to $35 in 2024. That places this record below the midpoint for ophthalmology clinicians in PA, where the typical reported total is $1,202.
Across 29 payments — averaging $23.19 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$673 in reported general payments places this provider in the 35th percentile of 920 ophthalmology providers in Pennsylvania.
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 |
|---|---|---|
| Prednisolone Acetate | 111 | $3,684 |
Paid to pharmacies, not to this prescriber.
