Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 90.9% of the total across 133 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 18 manufacturers reported payments, led by Bausch & Lomb Americas Inc. at 26.4% of the total. 2025 is the largest year on record at $1,801, 3.0 times the $609 reported in 2019. 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.
Across 133 payments — averaging $57.37 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
