  • Page 6: Theory Of Operation

    D.O.R.C. MICRO DIATHERMY SYSTEM Theory of operation Diathermy is used in operations for retinal detachment to produce a burn of the pigment epithelium. This burn is obtained by the applications of localized RF current on the sclera. A. Why High Frequency 13.56 MHz Power ? The following consideration resulted in the selection of the 13.56 MHz : Clinical tests have established that this frequency produces optimum burns of the pigment epithelium with the least possible damage to adjacent tissue such as the sclera and choroid.
  • Page 7 D.O.R.C. MICRO DIATHERMY SYSTEM C. Factors affecting a Diathermy burn : Several factors affect the nature of a burn obtained in scleral diathermy applications : 1. Voltage The intensity of the burn is proportional to the voltage level for any given frequency.
