Glaukos Corp
A California eye-care company making tiny implants and dropless treatments for glaucoma and other eye conditions, its signature iStent is a micro-sized device placed in the eye to lower pressure. Founded in 1998, it pioneered micro-invasive glaucoma surgery with the first human implant of its stent in 2001. The name comes from ancient Greek "glaukos," meaning gleaming or blue-gray—the same root as the word "glaucoma."

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 6 months: -50.6K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
