Anterior capsulotomy with a pulsed-electron avalanche knife.
PURPOSE To evaluate a new pulsed-electron avalanche knife design for creating a continuous curvilinear capsulotomy (CCC) and compare the CCC with a mechanical capsulorhexis. SETTING Department of Ophthalmology, Stanford University, Stanford, California, USA. METHODS In this study, CCCs were created in freshly enucleated bovine eyes and in rabbit eyes in vivo. The cutting velocity was adjust...
متن کاملPulsed 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 کاملPulsed electron avalanche knife for capsulotomy in congenital and mature cataract.
The pulsed electron avalanche knife (PEAK-fc, Carl Zeiss Meditec) is an electrosurgical cutting device that allows precise "cold" and traction-free tissue dissection. We describe its applicability and safety for anterior capsulotomy in a child with congenital cataract and an adult patient with mature cataract. The PEAK-fc was set at a voltage of 600 V and a pulse repetition rate of 80 Hz. Anter...
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...
