Pulsed electron avalanche knife in vitreoretinal surgery.
PURPOSE To evaluate the advantages, disadvantages, safety, and surgical applicability of the pulsed electron avalanche knife (PEAK-fc), a new electrosurgical knife for "cold" and tractionless cutting, in vitreoretinal surgery. PEAK-fc is equipped with an integrated fiberoptic that makes bimanual procedures in intraocular surgery possible. METHODS A prospective consecutive trial of 18 eyes in ...
متن کاملPrecision and safety of the pulsed electron avalanche knife in vitreoretinal surgery.
BACKGROUND We have developed a new surgical instrument, called the pulsed electron avalanche knife (PEAK; Carl Zeiss Meditec, Jena, Germany), for precise, "cold," and tractionless dissection of tissue in liquid media. OBJECTIVE To evaluate the 3-dimensional damage zone induced by the PEAK compared with 2 other standard intraocular surgical instruments, diathermy and retinal scissors. METHOD...
متن کاملPulsed electron avalanche knife (PEAK) for intraocular surgery.
PURPOSE To develop a better and more economical instrument for precise, tractionless, "cold" cutting during intraocular surgery. The use of highly localized electric fields rather than laser light as the means of tissue dissection was investigated. METHODS A high electric field at the tip of a fine wire can, like lasers, initiate plasma formation. Micrometer-length plasma streamers are genera...
متن کاملPulsed electron avalanche knife: new technology for cataract surgery.
BACKGROUND The pulsed electron avalanche knife (PEAK-fc) is a new pulsed electrosurgical device that allows for precise, "cold" and traction-free tissue dissection. AIM To evaluate the surgical applicability, safety and potential complications of PEAK-fc in complicated cataract surgery. METHODS The study included five children with congenital cataracts, two patients with advanced senile cat...
متن کاملEffects of the pulsed electron avalanche knife on retinal tissue.
OBJECTIVES To evaluate the precision of retinal tissue dissection by the pulsed electron avalanche knife (PEAK) and to assess possible toxic effects from this device. METHODS To demonstrate precision of cutting, bovine retina (in vitro) and rabbit retina (in vivo) were incised with the PEAK. Samples were examined by scanning electron microscopy and histologic examination (light microscopy). T...
