title: Machines and cutters: Constellation®.
abstract: The Alcon Constellation® provides state-of-the-art technology for vitrectomy surgery. Its innovative features include utilization of high-speed and small-gauge vitrectomy systems, surgeon-controlled duty cycle, fine intraocular pressure control, and integrated laser and intraocular gas mixing capabilities. The goal of vitrectomy surgery is the safe and efficient removal of vitreous while avoiding iatrogenic retinal tears or iatrogenic incarceration of retinal tissue. This requires the removal of vitreous in a controlled manner while maintaining safe levels of intraocular pressure. The Alcon Constellation contains improvements in technology that allow a surgeon to consistently accomplish these goals.
