Abstract
PRACTICE SURGERY using human cadaver eyes can be of benefit to the learning surgeon. However, corneal edema, which is often present in cadaver eyes, impairs visualization of the intraocular structures. Although the corneal epithelium can be removed to improve visualization, clarity usually remains compromised owing to stromal edema (Figure 1).For practicing delicate microsurgical intraocular techniques, such as continuous curvilinear capsulorrhexis, 1 phacoemulsification, and pars plana vitrectomy, a clear intraocular view is essential.
