Glaukos is growing revenue at 41% annually, leads its peer group in growth, and carries positive price momentum with a golden cross technical setup, while analyst sentiment is constructively bullish and news flow is favorable. However, the stock is trading roughly 12% above the entry price where the risk/reward is mathematically attractive—at the current price only 4.5% separates the stock from the analyst target while potential downside is materially wider—and four high-severity revenue concentration risks alongside an expensive valuation (PEG 2.59) argue for waiting rather than chasing.

About Glaukos Corporation
About Glaukos Corporation
Glaukos' glaucoma franchise — the iStent family (first FDA-cleared in 2012) and the iDose TR intracameral travoprost implant (FDA-approved December 2023) — accounted for approximately 83% of 2025 net sales, with the iLink corneal cross-linking platform contributing approximately 17%. U.S. customers represented 74% of net sales in 2025 and international customers 26%, with no single customer exceeding 10% of total net sales. Epioxa, an epi-on corneal cross-linking therapy, received FDA approval in October 2025 with commercial launch planned for early 2026.
Glaukos generates revenue through a U.S. direct sales force targeting ambulatory surgery centers, hospitals, and private practices, and through direct subsidiaries and distribution partners in Australia, Brazil, Canada, Germany, Japan, and the United Kingdom. The iStent family and iDose TR are reimbursed by Medicare and major private payers; physician fee reimbursement for iDose TR continues to be standardized across Medicare Administrative Contractors via temporary CPT codes. Manufacturing for the iStent and iDose product lines is concentrated at a sole campus in San Clemente, California, and the company relies on sole-source third-party suppliers for certain device and drug components. Glaukos competes in glaucoma primarily against Alcon, AbbVie, Sight Sciences, and Iantrek, and holds the only FDA-approved bio-activated pharmaceutical for keratoconus.

Local coverage determinations finalized by five of seven Medicare Administrative Contractors in November 2024 confirmed non-coverage for surgical MIGS procedures performed in combination with other surgical MIGS procedures, disrupting traditional ordering patterns and potentially weighing on U.S. glaucoma revenue through 2025 and beyond. The iDose platform's longer-term trajectory depends on Phase 2b/3 trial outcomes for the second-generation iDose TREX and the Phase 3 iDose TRIO program; if those trials fail to support expanded indications, the franchise may remain confined to the first-generation travoprost implant in open-angle glaucoma and ocular hypertension.
