Document Type and Number:
Japanese Patent JP2001518346
Kind Code:
A
Abstract:
A rotatable electrosurgical apparatus for reprofiling a cornea is described. The apparatus includes one or more electrosurgical electrodes that extend radially outward from a center point. The electrodes are shaped to reform at least a portion of an anterior surface of the cornea. The electrodes are disposed on an electrode support, which is rotatable. The electrodes project from the bottom of a rotary handle, which rotates the electrodes about a central visual axis of the cornea. The rotary handle has a hollow bore and a viewing port. The apparatus includes a support base having a base ring for positioning on the eye. The base ring can hold a solution against the eye to even out irregularities in the cornea. The apparatus may include pads to exert pressure on the cornea to cause the cornea to bulge in desired areas. These bulged areas are more easily modified by the electrodes when energized. The pressure pads take different forms depending upon whether they are used for the correction of myopia, hyperopia or astigmatism.
