IntraLase Corporation

Venture Round in 2000
IntraLase Corporation is a leader in the first step of LASIK surgery, the most common means of surgical vision correction. They design, develop and market a laser, related software and disposable devices used to create a cut of tissue across the cornea of a patient’s eye, or a corneal flap, which is the first step in LASIK surgery. Their advanced laser technology improves the safety, precision and visual acuity of LASIK surgery by providing a computer-controlled laser solution as an alternative to the traditional method of creating the corneal flap using a hand-held mechanical, metal-bladed device called a microkeratome. They believe their product offering will become the new standard of care for corneal flap creation. As of April 2, 2007, IntraLase Corp. was acquired by Advanced Medical Optics Inc.
