Paper Abstract

The cornea may be reshaped to correct for hyperopia by selective shrinkage of collagen in the stroma using radio frequency (RF) current from a needle electrode. Pulsed current is used to maximize therapeutic effect while minimizing radiating thermal damage. Finite difference numerical models of the electric fields and resulting thermal events were used to study the process parameters. The models were calibrated by comparison to histologic data using predicted and measured loss of birefringence in collagen as the standard of comparison.
