title: An experimental model for the evaluation of vitrectomy instruments.
abstract: A scleral window was designed for implantation in human autopsy eyes. This model provides direct visualization of the pars plana, vitreous base and peripheral retina. Using this model, one can directly observe vitrectomy instruments entering the globe, and can evaluate the cutting ability of a variety of instruments. The model can also be used to provide practical experience, analogous to clinical vitrectomy, and is therefore useful as a training device.
