Organization and Basis of Presentation Organization and Business Glaukos Corporation (Glaukos or the Company), incorporated in Delaware on July 14, 1998, is an ophthalmic pharmaceutical and medical technology company focused on developing novel dropless platform therapies and commercializing associated products for the treatment of glaucoma, corneal disorders, and retinal diseases.

Glaukos’ first-generation corneal cross-linking therapy, known as Photrexa, which requires removal of the corneal epithelium, received U.S. FDA approval in 2016.
