A contact lens as an artificial cornea for improved visualization during practice surgery on cadaver eyes.

Objective: To describe the use of a polymethylmethacrylate contact lens as an artificial cornea to enhance visualization for practice surgery using cadaver eyes.

Design: The opaque cornea of a cadaver eye is removed by trephination. Cyanoacrylate glue is used to secure a large-diameter polymethylmethacrylate contact lens to the corneal rim.
