Staar Surgical Co
A maker of implantable lenses for the eye, STAAR Surgical is best known for its EVO ICL — a tiny, foldable lens surgically placed behind the iris to correct nearsightedness as an alternative to glasses, contacts, or LASIK. Founded in 1982 by Tom Waggoner and Dr. Thomas Mazzocco, the company pioneered the first foldable intraocular lens for cataract surgery. Its lenses are made from Collamer, a proprietary material whose name blends "collagen" and "polymer," helping the eye accept the implant as its own.

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 3 years: +7.35M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
