Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $131,351 of the $141,295 with a category attached, or 93.0%. Topcon Healthcare, Inc. accounts for 97.0% of it on its own, with 15 other manufacturers making up the rest. Reporting peaked in 2022 at $85,180 and has fallen 98.0% since, to $1,713 in 2025. Among optometrist clinicians in CA 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.

How this compares
$141,295 in reported general payments places this provider in the 95th percentile of 6,778 optometrist providers in California.
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.
