Flying L Partners

Flying L Partners is a Los Angeles-based investment firm partnering with entrepreneurs to accelerate innovations entirely within the ophthalmology space. The narrow vertical focus is consistent with the wave of ophthalmology specialist funds that emerged in response to category complexity, long development timelines, and surgeon-driven adoption dynamics. Founders building ophthalmic devices, surgical instrumentation, novel implants, ophthalmic therapeutics, dry eye and ocular surface products, retinal imaging, and vision-focused digital health fit the thesis. The geographic base in Los Angeles also provides access to the West Coast ophthalmic device cluster.

The fund invests at Seed and Series A with check sizes of $1M to $5M. It is based in the United States and operates across medical devices and MedTech and pharma and therapeutics, both filtered through ophthalmology. No AI focus is stated.

Founders should approach with a clear regulatory plan, evidence of surgeon or clinical interest, and a perspective on how their technology fits within the ophthalmic surgical or pharmaceutical workflow. Given the firm’s specialization, founders without an ophthalmology angle are unlikely to find a fit regardless of broader healthcare merit. Limited public information is available about specific partners and complete portfolio. Warm introductions through ophthalmic surgeons, KOL networks, and West Coast ophthalmic device veterans are typically the most credible paths in.
