title: Machines and Cutters: Stellaris PC.
abstract: The Stellaris PC (Bausch & Lomb) is a versatile platform that allows surgeons to perform both anterior segment and posterior segment surgeries. It was developed based on the Stellaris microincision cataract surgery system and can therefore perform <2-mm coaxial or bimanual microincision cataract surgery in combination with posterior segment surgery. Similar to Millenium, its predecessor, the Stellaris PC has an open architecture with modular design that allows products and instruments manufactured by other companies to be used with the system. Vitrectomy can be performed using the traditional 20-gauge system or with microincision 23- or 25-gauge transconjunctival sutureless vitrectomy systems. The special design of the vitreous cutter with increased port area, improved fluidics, and optimized port open time makes the Stellaris PC an efficient system for performing microincision vitrectomy surgery. This article will describe the design, features, and details of various components of the Stellaris PC, including machine controls, entry site alignment trocar/cannula system, fluidics, and high-speed vitreous cutter, as well as its unique illumination system.
