Porcine vitreous was obtained within 12 to 24 h of Vitrectomy. 2021 May 10. doi: 10.1097/IAE.0000000000003215. Vitrectomy is a surgical procedure undertaken by a specialist where the vitreous humor gel that fills the eye cavity is removed to provide better access to the retina. Hypersonic vitrectomy uses ultrasound to perform vitrectomy. This probe liquefies the vitreous instead of cutting it. It also liquefies the Jorge I. Calzada, MD, FACS CEO and Founder, Deep Blue Retina, Memphis, TN, and Adjunct Professor of The HV produced consistent water and vitreous flow rates across the range of US power and aspiration levels tested. Despite the potential advantages in fluidics, the performance of In proportional vitrectomy the cut-rate remains constant, whilst the vacuum is controlled by the foot treadle. In 3D (Dual Dynamic Drive) vitrectomy both the cut rate and vacuum are controlled by the foot pedal. These are customizable and often inversely related (i.e. as the vacuum increases the cut rate decreases). Figure 7. Hypersonic vitrectomy overcomes flaws of traditional systems March 11, 2018 Michelle Dalton, ELS Using ultrasonic power to actuate a vitrectomy probe (hypersonic Hypersonic vitrectomy is a new technology that allows for smaller-gauge vitrectors with efficiency similar to that of a guillotine-based device, Dr. Stanga said. Dr. Awh explains the ultrasound technology and compares it with traditional, guillotine-style cutters. hypersonic vitrectomy system uses low amplitude motion of the tip to create oscillating high-speed flows near the port that cut vitreous. This novel method of vitreous removal was Purpose of review: To review the development of hypersonic vitrectomy and present the first case series in the United States. Hypersonic vitrectomy is the latest machine in which we use ultrasound to liquify vitreous. Various procedures were performed using this technique, ranging from posterior segment surgeries to posterior chamber ruptures with nuclear WAIKOLOA, Hawaii Hypersonic vitrectomy is a relatively new method with the potential to innovate vitreoretinal surgery, but surgeons have more to learn about it, Vitreous liquifies at the end of the port and is then aspirated. Until recently, 27-gauge vitrectomy was considered the latest entrant in this arena. Hypersonic Vitrectomy System Highlights Downloads Exclusive to Stellaris Elite , the Vitesse hypersonic vitrectomy system represents a revolutionary approach to vitreous removal. Since the technique was first described in 1973, it has been used in 148 eyes in a variety of conditions wit The availability of hypersonic vitrectomy in the current surgical practice opens a new era in vitreoretinal surgery, but the performance of this technology needs to be further optimized, mainly for the occurrence of inadequate vitreous liquefaction and Vitreous strands formation. Methods Two vitrectors were tested, a prototype, ultrasound-powered, hypersonic vitrector (HV) and a GV. Hypersonic vitrectomy may be a promising new alternative to the currently available guillotine-based technologies. From 27 September 2017 to 4 December 2017, 64 patients underwent hypersonic vitrectomy with 20 patients having conventional 23-ga vitrectomy for comparison. Purpose To evaluate porcine vitreous flow and water flow rates in a new prototype hypersonic vitrectomy system compared to currently available pneumatic guillotine vitrectors (GVs) systems. The hypersonic vitrectomy probe does not cut vitreous or tissue in a conventional manner. Instead, the device virtually liquefies tissue as it enters a port oscillating at 1.7 million cycles per minute. Dr. Awh, of Tennessee Retina, Nashville, TN, said the liquefaction occurs at the outer margins of the port. In a hypersonic system 1, low amplitude ultrasonic motion of the tip is used to create oscillating, high-speed vitreous liquefaction and flow near the outer surface of the port. Because there is only one needle rather than two, there is no chance of trapping vitreous strands between the port edge and the needle. 1 In contrast to guillotine cutters, the hypersonic vitrectomy instrument Hypersonic vitreous liquefaction drives breakthrough innovation in vitrectomy Ocular Surgery News | Hypersonic vitrectomy, which uses hypersonic reciprocating hydraulics It can also be used in cases of PC rupture with retained nuclear fra So the single lumen gives you an effectively Vitesse is not a pneumatic cutter, its 100% open 100% of the time. Recent findings: From 27 September 2017 to 4 December Peripheral vitrectomy during a rhegmatogenous retinal detachment repair using the Vitesse probe. This review discusses the benefits of hypersonic vitrectomy in comparison with the traditional method (pneumatic guillotine cutters). The hypersonic vitrectomy system uses low amplitude ultrasonic (US) motion of the tip to create oscillating high speed flows near the port that cut vitreous. Now, however, hypersonic vitrectomy has come into the picture.Hypersonic vitrectomy is performed Hypersonic vitrectomy offers potential significant advantages in fluidics compared with traditional Microincisional vitrectomy surgery (MIVS) has now become standard, with 20-gauge vitrectomy being rarely performed. In 2017, Bausch + Lomb introduced the Vitesse hypersonic vitrectomy instrument for its Stellaris Elite vitrectomy machine. The hypersonic liquefaction of vitreous may decrease iatrogenic traction on the retina and result in greater flow stability. Hypersonic Vitrectomy Carl C. Awh, MD, Timothy G. Murray, MD, MBA Show Description + Carl C. Awh, MD, speaks with Timothy G. Murray, MD, MBA, and details his experience with hypersonic vitrectomy, a new technology for removing the vitreous. With the first major innovation in vitrectomy technology since the early days of pneumatic guillotine cutters, hypersonic vit rectomy has been shown to be an efficient, effective and The preoperative VITESSE Hypersonic Vitrectomy System Vitesse hypersonic creates a near liquifying effect in a controlled area around the cutter, which offers higher levels of precision cutting to the surgeon. Ultrasonic fragmentation (USF) can be used to fragment various tissues such as the lens, the vitreous, the iris, and the ciliary body, so that they may be aspirated through a 23-gauge canula. Show Description + Hypersonic vitrectomy (Vitesse, Bausch + Lomb) utilizes ultrasound power of 28.7 KHz and a stoke length of 0 to 60m for liquefaction of The availability of hypersonic vitrectomy in the current surgical practice opens a new era in vitreoretinal surgery. The new iterations of ultrasonic vitrectomy probes, now called hypersonic vitrectomy, reliably remove vitreous and shear collagen fibers without the use of a guillotine cutter. Hypersonic vitrectomy not only takes small little particles of the vitreous gel, but it doesn't have a needle and needle design. Twenty-three-gauge hypersonic vitrectomy: real-world surgical evidence Retina. Hypersonic vitrectomy offers retina specialists a rare opportunity to help change the landscape of surgery with a disruptive technology. Also, to identify the working parameters that provide the best balance between acceleration and flow For eager surgeons with an open mind, hypersonic HYPERSONIC VITRECTOMY The most novel instrument regarding vitreous cutters is the new 23-gauge hypersonic vitrectomy probe exclusively compatible with the Stellaris Elite ( Figure 2).
