To try to recreate the images reported by patients during vitreous surgery in a model eye.
A fluid-filled model eye with a posterior frosted translucent surface which corresponded to the retina was used. Three holes were made in the model eye through which an endoillumination pipe and intraocular forceps could be inserted. A thin plastic sheet simulating an epiretinal membrane and an intraocular lens (IOL) simulating a dislocated IOL were placed on the retina. The images falling on the posterior surface were photographed from the rear. The images seen through the surgical microscope were also recorded.
The images from the rear were mirror images of those seen through the surgical microscope. Intraocular instruments were seen as black shafts from the rear. When the plastic sheet was picked up, the tip of the forceps was seen more sharply on the posterior surface. The images of the dislocated IOL from the posterior were similar to that seen through the surgical microscope, including the yellow optics and blue haptics.
Intravitreal objects can form images on the surface of a model eye. Objects located closer to the surface are seen more sharply, and the colour of the objects can be identified.
尝试在模型眼中重现玻璃体手术中患者报告的图像。
使用充满液体的模型眼，其后部磨砂半透明表面与视网膜相对应。在模型眼中钻三个孔，以便插入内窥镜和眼内镊。在视网膜上放置一块模拟视网膜前膜的薄塑料片和一个模拟脱位的人工晶状体 (IOL) 的 IOL。从后面拍摄落在后表面上的图像。从手术显微镜中看到的图像也被记录下来。
从后面看到的图像是通过手术显微镜看到的图像的镜像。从后面看，眼内器械是黑色的轴。当提起塑料片时，镊子的尖端在后表面上看得更清楚。从后面看到的脱位 IOL 的图像与通过手术显微镜看到的相似，包括黄色光学元件和蓝色襻。
眼内物体可以在模型眼的表面形成图像。位于表面附近的物体看得更清晰，并且可以识别物体的颜色。
