A practice model for trabecular meshwork surgery.

Models for practicing ophthalmic surgery are a necessary part of all ophthalmic training. Herein, we describe a method for preparing human donor cadaveric eyes with direct visualization of the anterior chamber angle for practicing trabecular meshwork surgery. This model can be adapted for use with both fresh and formalin-fixed eyes. The use of formalin-fixed eyes decreases the risk of infection transmission inherent with human cadaveric eyes, allows prepared eyes to be stored indefinitely, and can be reused until all of the trabecular meshwork has been exhausted in surgery. We describe the application of this model for the technique of ab interno trabeculectomy using the Trabectome system for treating open-angle glaucoma.
