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.
研发一种带有集成输液套管的临时性角膜移植片，以尽量减少在角膜混浊眼的玻璃体切割术中视网膜并发症的发生。
对宽视野临时性角膜移植片进行了改良，使其包含一个集成输液套管。20号套管从角膜边缘的周边开始，弯曲90度，穿过角膜圆柱体周边后进入眼内。
输液宽视野临时性角膜移植片已成功应用于3例患者，无需放置单独的输液装置，而单独输液装置有导致医源性视网膜裂孔或视网膜脱离的风险。与标准临时性角膜移植片相比，输液临时性角膜移植片后表面的液滴凝结减少。
我们研发了一种带有集成输液套管的宽视野临时性角膜移植片，用于严重角膜混浊眼的玻璃体切割术。该装置消除了与睫状体扁平部输液套管相关的并发症风险。
