The Constellation Vision System is a dual pneumatic drive technology vitrectomy machine with a Venturi vaccum pump. This was particularly noticeable when using venturi pumps and peristaltic pumps, however, this risk has been reduced [12, 17]. A new dual port cutter system for vitrectomy surgery. LAVAL, Quebec, Jan. 8, 2018 /PRNewswire/ -- Bausch + Lomb, a leading global eye health company and wholly owned subsidiary of Valeant Pharmaceuticals International, Inc. (NYSE: VRX and TSX: VRX) ("Valeant"), today announced that it has received CE Mark from the European Commission for the Stellaris Elite Vision Enhancement System, the company'. The vitrectomy efficiency was calculated from the aspirated mass (g) within 30s. The aperture of the different vitrectomy probes was filmed with a high-speed camera. Hypersonic vitrectomy rests on the well-utilized physics of ultrasound probes for intraocular surgery. Fang, S. Y., DeBoer, C. M. T. & Humayun, M. S. Performance analysis of new-generation vitreous cutters. Regarding fluid control, the aspiration flow at the cutter orifice is difficult to control, as liquid removal depends not only on the vacuum pressure, but particularly on the viscosity of the fluids. Current microincision vitrectomy systems (MIVS) promote self-sealing sutureless sclerotomies, such as the 23-gauge sclerotomies developed by Eckardt, and the further minimization to 27-gauge by Oshima et al. Quantity: Dr. Kevin Blinder, MD - Bi-Blade Stability, 3365 Tree Court Industrial Blvd.St. Pavlidis, M. Two-Dimensional Cutting (TDC) Vitrectome: In vitro flow assessment and prospective clinical study evaluating core vitrectomy efficiency versus standard vitrectome. 3365 Tree Court Industrial Blvd.St. Request a New Catalog. window.mc4wp = { It had a lot of firsts for the industry, said the director of surgical equipment research and development at Bausch + Lomb. 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. The combination of continuous yet reduced flow gives the surgeon increased control of vitrectomy dynamics. 2014;34(3):55867. 1. We developed the FreeFlow infusion system to provide surgeons with great control during their high flow vitrectomy procedures, Chuck Hess, vice president and general manager, U.S. Surgical, Bausch + Lomb, said in a company news release. The states of aggregation are fluid ( 1020C) or firm (22 37C), depending on the temperature. Historically, removing vitreous has required variations on vitreous cutter systems that have an opening at the instrument tip that closes at high frequency in a guillotine fashion, which cuts the vitreous collagen fibers while they are being aspirated. The SK-650A retinal camera is a nonmydriatic camera that is also DICOM-compatible. } The smaller vitreous pieces obtained with higher cut rates are more easily aspirated through the probe; hence, the relationship between cut rate, duty cycle, and flow rate becomes more dynamic.8, Duty cycle is highly variable from one vitreous cutter to another, but there is an inverse correlation between cut rate and duty cycle in that the higher the cut rate the lower is the duty cycle.9, At high-speed velocity, most conventional cutters decrease their DC, or percent of port open time, throughout the cut cycle; and consequently, there is an expected decrease in the water and vitreous flow rates and a corresponding increase in the surgical time required. Why compromise when Stellaris Elite offers both cataract and retina capability in a single platform? With the Vitesse, we are able to perform vitrectomy and remove lens material without needing to switch to a fragmatome. The area under the curve analysis showed differences in efficiency between vitrectomy systems. For comparing the efficiency and characteristics of modern vitrectomy systems, the following systems were examined: Constellation Vision System (Alcon, Forth Worth, USA), EVA (Dutch Ophthalmic Research Center, DORC), Zuidland, The Netherlands), megaTRON S4HPS (Geuder, Heidelberg, Germany), and Stellaris PC (Bausch&Lomb, New Jersey, USA). I have performed peripheral vitrectomy with the hypersonic system adjacent to retinal neovascularization in sickle cell disease, and the decrease in retinal traction becomes even more evident in these cases, which are prone to peripheral retinal tears at the base of the neovascularization. PDF Bausch & Lomb Stellaris PC - Vitreoretinal and Cataract Eye Surgery 3) of megaTRON S4HPS and EVA showed significantly higher (p<0.0001) mass aspiration of water compared to its mono-beveled vitrectors (Fig. 2005;25:20811. This case required the ultrasonic capacity of the Vitesse system to perform the vitrectomy and removal of lens fragments in tandem. For Constellation 20G probes significantly less (p<0.0001) mass was aspirated at 5000cpm compared to 0cpm. Google Scholar. A comprehensive portfolio of high-performance laser probes enables exceptional access and surgical efficiency. J Ophthalmol. In 1992 we launched the first dual linearcontrol technology with the PREMIERE system, that had a similar look and user interface to the DAISY, but through rigorous design methods was more reliable and could be used at altitudes above 1500m. Retin Cases Brief Rep. 2009;3(1):647. 6). A study carried out to compare this new technology developed by B&L to currently available pneumatic guillotine vitrectors (GVs) systems concluded that this might be a promising new alternative to the currently available guillotine-based technologies.15. 2018, the year our new liquefaction technology for vitreous removal has been introduced onto the market. 1975;7(585e8):5914. Rossi T, Querzoli G, Angelini G, Malvasi C, Rossi A, Morini M, Esposito G, Micera A, di Luca NM, Ripandelli G. Hydraulic resistance of vitreous cutters: the impact of blade design and cut rate. Bausch&Lomb Stellaris User manual - ManualMachine.com Comparing mono to dual-bladed probes, dual-bladed probes (Fig. Bausch & Lomb Stellaris PC - Vitreoretinal and Cataract Eye Surgery Features Dual light source with surgeon-selected color filters. Consequently, porcine vitreous shows a comparable viscosity and viscoelastic behavior to human vitreous [21, 22]. Repairs 2023 Bausch & Lomb Incorporated. Their Vacuflow Valve Timing Intelligence (VTi) technology uses high-sensitivity pressure sensors and computer-controlled operating pistons, which generate a fast vacuum response and reduce undesirable flow turbulences [18]. A great story on innovation, development, work and research that has taken us to the Stellaris in 2007 with the launch of the wireless foot pedal control and Attune energy management system. The dual-port design ofBiBlade greatly enhances efficiency due to the unique design that allows for cutting without port closure. Improvements in tip design, vibration frequency, and machine software control of tip dynamics have enabled us to reinvent vitrectomy using ultrasonic probes. One could speculate that the higher aspiration volume of the EVA system compared to their competitors is based on their novel pump system, which is neither a peristaltic nor a venturi pump. Dual-bladed probes of the EVA and megaTRON S4HPS systems showed constant vitreous aspiration compared to an oscillatory and enhanced vitreous movement of the mono-bladed probes of the Constellation Vision System, megaTRON S4HPS and Stellaris PC systems. Eyes were explanted postmortem by a slaughterhouse approved in accordance with the guidelines of the German Regulations for Animal Protection and Slaughter, issued by the German Federal Ministry for Consumer Protection, Food and Agriculture in 2012.

Here, double-bladed vitrectors allow preforming forward and backward cutting of vitreous during blade movement, without complete closure of the cutter opening, which stands in contrast to standard guillotine-like cutters that have an increasing closure time at higher cut rates. However, retinal traction could very well be overcome by using dual-port cutters with smaller lumina in 25/27-G cutters, as discussed in a more recent review [25]. No Comments. window.mc4wp.listeners.push({ forms : { on: function (event, callback) { Experience the stability and efficiency of dual-port cutting with Bi-Blade vitrectomy cutters for the Stellaris Elite platform. Moore describes it as more aesthetically pleasing than its predecessors.

Water has a known viscosity of 1mPa s, which has been confirmed in our tests. I have learned to move the tip of the device much more slowly and deliberately than with guillotine cutters. Of the three duty cycles to choose from in the Constellation Vision System (Port Biased Open for core-vitrectomy, Port Biased Closed), we chose the Port Biased Open, given its presumed higher vitrectomy efficiency. Experiences with partial vitrectomy in patients with proliferative diabetic retinopathy. } BAUSCH + LOMB is now celebrating the 35th anniversary of the first disposable guillotine cutter in the world.

About Bausch + Lomb Bausch + Lomb is dedicated to protecting and enhancing the gift of sight for millions of people around the world - from the moment of birth through every phase of life. This has been achieved by engineering a metallic probe with a small opening at the distal tip. 1975;80(4):7645. Intraocular lenses, monofocal and premium. I feel that these new versions of the technology have the potential to replace even our most efficient and safe standard vitrectomy probes. For surgeons, it is crucial to gain information about the oscillation of the retina in critical situations and the reproducibility of suction and cut rates to manipulate the vitreous without harming the retina. Based on the electronically recorded twist moment measured in mPa s/cP, which depends on the geometry and rotational speed of the spindle, the viscosity can be measured in mPa s/cP (1mPa s=1 cP [centi-Poise]). 3845 Corporate Centre Drive. For mono-bladed probes, the area under the curve analysis displays the aspirated mass against cut-rates from 06000cpm at a fixed 600mmHg aspiration pressure. All information and materials on this site pertain to the U.S. only, unless otherwise indicated. The probe vibrates at 31 kHz with a linear displacement of 60 m. We have reduced the need for a duty cycle while creating a consistent flow rate and continuous holding force. This innovative design used with the Stellaris Elite offers an effective 15,000 cuts per minute (cpm) rate, resulting in increased flow efficiency and control compared to prior generation guillotine cutters. Occlusion of the small opening is easy, and the ability to utilize linear high vacuum allows for controlled grasping of the posterior hyaloid to lift it over the optic nerve and extend the separation to the periphery. The aspiration of Pluronic gel (g) as a function of cut rate and vacuum pressure for 20- and 23-gauge vitrectomes for the Stellaris PC, Constellation Vision System, vitrectomy systems. The design used with the Stellaris Elite surgical platform offers up to 15,000 cuts per minute, allowing for increased flow efficiency and control. A further feature was a patented user interface inspired by automated teller machines. Bausch + Lomb Announces New Scientific Data and Analyses Featuring **Compared to traditional single-port cutters in BSS on systems in 7500 CPM mode. The ability to have linear control of vacuum while maintaining proportional flow and engaging vitreous is a significant benefit over traditional systems. PluronicF127 in a concentration of 17.5% and with an estimated viscosity of around 40mPa s was used in our experiments. They will always have pulsatile flow through the probe simply because of the opening and closing of the cutter opening. (Accessed: 10th April 2018). The megaTRON S4HPS and EVA dual-bladed probes did not significantly increase nor decrease the weight of the aspirated mass compared to mono-bladed probes. volume7, Articlenumber:8 (2021) de Oliveira, P.

For EVA, at least at 6000cpm, significantly more vitreous (p<0.01) was aspirated using its dual-bladed compared to its mono-bladed probe. Bausch + Lomb says its Bi-Blade cutters cut in both the forward and backward directions, enabling two cuts per cycle, as opposed to single-port cutters. While egg-white contains proteins such as albumins, mucoproteins and globulins, porcine vitreous proteins are mostly made up of hyaluronan-derived uronic acid and collagen [20], comparable to the collagen fibers and hyaluronic acid of human vitreous. 2016;2:28. For vitreous surrogates such as egg white and porcine vitreous, we found an increase in aspirated mass, depending on the vacuum pressure and cutting movement. As expected, 23-gauge vitrectors removed about half the amount of vitreous compared to 20-gauge ports. Bausch + Lomb Announces New Scientific Data and Analyses Featuring The new probe joins the available 25- and 27-gauge Bi-Blade cutters as options in the Bi-Blade portfolio. In contrast, the EVA system employs a peristaltic two-cylinder pump mechanism. With an unrivaled combination of leading-edge technologies, Stellaris Elite is optimized to deliver precise control and extraordinary efficiency to a wide range of cataract and retina procedures. Despite the impression that the vitrectomy is proceeding more slowly, the actual surgery time is equal to or slightly less than during guillotine vitrectomy. 1975;80(5):83843. For each vitrector, videos were recorded with a stepwise increase in vacuum pressures and cut rates according to the aforementioned protocol. Int J Retina Vitreous. Vitrectomes were submerged in the test material, and vitrectomy was performed for each setting in triplicates for 30s. The aspirated test material was measured in grams as weight loss by means of elimination of vitreous through the vitrectomy system. Core vitrectomy with the Vitesse probe. BAUSCH + LOMB is now celebrating the 35th anniversary of the first disposable guillotine cutter in the world. News Release 1 MID Labs Vitreoretinal Ophthalmic Medical Devices.

Compared to traditional single-port cutters in BSS on systems in 7500 CPM mode. The rapid movement of the small tip while aspirating can shear vitreous collagen fibers at the metal edge of the tip orifice. Bausch + Lomb Shares Developments in Vitrectomy (OIS@ASRS 2016) It is time to leave the status quo and experience the truth about vacuum fluidics innovation. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Because the hypersonic system removes both vitreous and lens material indistinctly, it also eliminates the vitreous pulling that a standard fragmatome can create. Stay informed about news and articles for surgeons: (function() { One could expect even lower amounts of vitreous being removed using 25 or 27 G devices. Both substances may obstruct the cutter opening [19]. Springer Nature. Vitrectomy Equipment.
