—In an article in the Archives (1981;99:494-497), Parel et al alleged that bipolar bimanual diathermy was potentially unsafe. While no concerned clinician can fault a search for safety, I believe that the authors had no case report of damage caused by this method and had performed no animal experimentation either with bipolar bimanual diathermy, which they disagreed with, or the method that they recommended as being safer. They report only three cases with their method, which certainly does not prove that it is safer. The method of bipolar bimanual diathermy has been in use for six years worldwide by more than 300 clinicians of whom I am aware. I have used the method in more than 500 patients in a near 3,000-case series of pars plana vitrectomy. I have never experienced changes in the sclera or vacuoles in the lens that would be the early findings of
