Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $509,596 of the $520,593 with a category attached, or 97.9%. Glaukos Corporation accounts for 98.8% of it on its own, with 22 other manufacturers making up the rest. Reporting peaked in 2023 at $512,816 and has fallen 99.7% since, to $1,353 in 2025. Among ophthalmology clinicians in SD with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 161 payments — averaging $3233.50 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

How this compares
$520,593 in reported general payments places this provider in the 95th percentile of 52 ophthalmology providers in South Dakota.
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 | 107 | $4,209 |
| MoxifloxacinMoxifloxacin Hcl | 69 | $1,640 |
| Diclofenac Sodium | 28 | $324 |
