Anterior segment laboratory: Foreign body removal apparatus construction

1 May 2006


INTRODUCTION All optometric physicians must be skilled in foreign body removal from the human eye. To this end, an apparatus for effectively practicing various techniques is proposed, with the pig eye as the preferred model.

METHODS Assembly and application of a prototype for a pig eye holder is illustrated. Third year optometric students evaluated the device and questionnaires were completed to determine the value in practice.

RESULTS Overall, the eye model was a successful practicing tool for the removal of ocular foreign bodies. Minor adjustments to the appearance and presentation are needed to improve the likeness of the replica to that of a human eye.

CONCLUSIONS The proposed apparatus is an excellent teaching device. Ease of construction, reusability, and low cost make it invaluable. Simple modifications could improve the experience for students, and further testing using the model may provide beneficial information.
