<title>Device for viewing the insertion of foldable IOL into sectioned eyes from the posterior pole</title>

Abstract

The study of insertion and deployment of foldable IOL's in cadaver eyes is enhanced by viewing the process from the posterior pole position. A video system was constructed to view IOL placement in sectioned eyes from the posterior position. All tissue used in this study were prepared using the VISUALEYES Surgical Practice System (Visitec Co., Sarasota, FL). This system allows for the precise placement and resection of the proximal third of the posterior segment of the globe. The remaining two-thirds of the globe is then placed onto the eye holder, which allows the tissue to be viewed from the posterior position. After the tissue has been prepared and attached to the fixation plate, the entire assembly is attached to the video system. A variety of intraocular procedures can then be performed utilizing this system. Both anterior and posterior views can be video taped for later analysis. Parameters such as IOL diameter, haptic length, positioning of the IOL within the eye and unfolding characteristics can be assessed using this system. This paper discusses the development of this device and presents examples of its use in the study of foldable IOL deployment.
