Radiofrequency (RF) thermokeratoplasty uses RF currents to alter the curvature of the cornea by means of thermal lesions. An RF applicator which combined a microkeratome suction ring and a circular electrode was designed with the aim of creating circular thermal lesions in a predictable, uniform and safe way. An experimental study was conducted on ex vivo porcine eyes. A theoretical model was also designed. The experimental results showed a lesion depth of 34.2 ± 11.0% of corneal thickness at a… CONTINUE READING
