  • Method and apparatus for preventing and clearing condensation on the lens during a fluid-gas exchange portion of a pars plana vitrectomy
    Patent number: 5919158
    Abstract: An infusion cannula for use in clearing and preventing condensation on the posterior surface of an artificial lens during the fluid-gas exchange portion of a pars plana vitrectomy is described. The infusion cannula directs the flow of gas entering the eye toward the posterior surface of the lens. The moisture content of the gas supplied to the infusion cannula is minimized in order to increase the effectiveness with which condensation is removed or prevented. Additionally, the temperature of the gas supplied to the infusion cannula is controlled to further increase the effectiveness with which condensation is removed.
