<p>An ophthalmic method and apparatus preferably for removing the relatively soft cellular epithelium from a predetermined region of the relatively hard fibrous cornea of the eye preparatory to reshaping the cornea as by laser ablation or the like, preferably by an abrasive surface formed by the ends of a bundle of thin soft filaments constrained against lateral movement and rotatable to comminute and emulsify the epithelium into tiny removable cell-particles, with features, where desired, of concavely contouring the surface formed by the free ends of the filaments to correspond to the anterior convex cornea, and interiorly hollowing the bundle to provide an annular abrasive surface formed by filament ends surrounding the hollow. <MATH></p> |
