Abstract
To develop a temporary keratoprosthesis with integrated infusion cannula to minimize retinal complications during pars plana vitrectomy in eyes with an opaque cornea. The wide-field temporary keratoprosthesis has been modified to include an integrated infusion cannula. The 20-gauge cannula runs from the periphery of the corneal flange, bends 90 degrees, and enters the eye after passing through the periphery of the corneal cylinder. The infusion wide-field temporary keratoprosthesis has been used successfully in three cases without the need to place a separate infusion, which risks iatrogenic retinal breaks or retinal dialyses. Droplet condensation on the posterior surface of the infusion temporary keratoprosthesis was reduced compared with the standard temporary keratoprosthesis. We have developed a wide-field temporary keratoprosthesis with an integrated infusion cannula for use during pars plana vitrectomy in eyes with severe corneal opacity. This device eliminates the risk of complications related to the pars plana infusion cannula.
