Corneal drape for use in performing a photorefractory keratectomy procedure

摘要

The invention contemplates a template or mask for use in aid of a photorefractory keratectomy procedure for recurvature of a cornea. The template or mask is of flexible sheet material that is so fenestrated or otherwise configured as to be self-adherent to the cornea in the region outside of and surrounding the central optically used area of tissue- ablating recurvature, the template being configured to provide ready centering on the visual axis. The self-adherence is relative, intended only to serve for correct centering, and for moisture-retention, regardless of the corneal curvature to which it is applied.
