Although increasing the port diameter of a vitreous cutter would increase the flow, the system reduces its effectiveness as the port becomes larger.3, Although it is feasible to create even smaller instrumentation, the clinical outcomes and applicability may not necessarily warrant it. Unlike a traditional infusion line that extends vertically off the top of the cannula, this line extends at a 30-degree angle to the cannula, providing the surgeon better access to the eye with less torqueing to direct infusion more centrally. Am J Ophthalmol. Compared to traditional single-port cutters in BSS on systems in 7500 CPM mode. With its extensive range of available cutting, accessory and visualization options, as well as the Vitesse hypersonic vitrectomy system, Stellaris Elite is perfect for any practice and every vitreoretinal surgeon. For egg-white high standard deviations did not allow for the defining of significant differences between different vitrectomy systems using mono-bladed probes (Fig. Louis, MO 63122(800) 338-2020 (USA)BLSurgCustSvc@Bausch.com, Use of this site signifies your agreement to the Legal Notice and Privacy Policy. 2023 Bausch + Lomb.

Stellaris Elite - Bausch Surgical 1. The surgery was performed in its entirety using the 23-gauge Vitesse hypersonic system. REVIEW, Tuesday, June 13, 2023 | All Eyes On Evaporation. Given the homogeneity in viscosity of this Newtonian fluid, a cutting process is not necessary. Bausch + Lomb Medical Devices/Surgical. 2 years later, a further innovation came, in this instance through Storz OphthalmicInstruments, which later became part of BAUSCH + LOMB. Using powerful hypersonic technology, it liquefies vitreous for a new level of surgical control and precision. forms : { To attain higher efficiency, one should bear in mind that vitreous removal is influenced by the sclerotomy size, the duty cycle of the vitrector (cut rate and aspiration), the infusion pressure and the aspiration vacuum. The innovative tools in the Synergetics line, such as our 27 gauge endoilluminator, offer you the most modern instruments to perform the most current techniques in vitreoretinal surgery. callback: callback PubMed From a clinical perspective, this enables us to perform posterior lens removal through standard small-gauge cannulas, obviating the need for conjunctival peritomy and direct sclerotomies. From the smaller lens pieces to the larger lens pieces, we were able to remove all of the IOL remnants. 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. The platform features multiple advancements as well as the ability to integrate future technologies, such as the Vitesse hypersonic vitrectomy system, which is exclusive to Stellaris Elite vision enhancement system. The aspiration of water (g), egg white and porcine vitreous as a function of cut rate and vacuum pressure for 23-gauge dual-cut vitrectors for the megaTRON S4HPS and EVA vitrectomy systems. echnologies recently introduced two new products: the SK-850A visual field analyzer and the SK-650A retinal camera. Furthermore, the Dutch Ophthalmic Research Center (DORC) (Zuidland, The Netherlands) introduced a vitrector with two angled blades, promising improved fluid dynamics and higher cut rates [16]. 1972;10:6849. OMalley C, Heintz RM. With its dual-edge blade, the BiBladevitrectomy cutterdoubles the effective cut rate over single-edge vitrectomy cutters, allowing for faster procedures. The smaller opening diameter of the port, in comparison to the size of the port opening in the guillotine cutter systems, means that the flow through the port in milliliters per unit time is less than in the guillotine cutter systems. 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. It is time to leave the status quo and experience the truth about vacuum fluidics innovation. Article Stellaris Elite integrates cataract and retina capabilities into a single platform, maximizing immediate and long-term ROI. Advances in cutter technology | Bausch + Lomb Surgical It is not unusual to have potentially dangerous transient hypotony during fragmatome lensectomy because of a mismatch between infusion and aspiration flow. By considering its higher viscosity, less Pluronic gel was aspirated than water. All vitrectomy systems were evaluated using 20-gauge as well as 23-gauge vitrectomes submerged in water, 17.5% PluronicF127 gel, egg white and porcine vitreous without infusion pressure in an open beaker. The aspiration of porcine vitreous (g) as a function of cut rate and vacuum pressure for 20- and 23-gauge vitrectomes for the vitrectomy systems Stellaris PC, Constellation Vision System, megaTRON S4HPS and EVA. Both videos were recorded at 5000cpm and 200mmHg aspiration pressure. To analyze the characteristics of the vitrectomes and their duty cycles, high-speed videos were recorded (CR30002 high-speed video-camera, Optronis, Germany). Mohamed, S., Claes, C. & Tsang, C. W. Review of Small Gauge Vitrectomy: Progress and Innovations. A Convenient Solution for Office Injections. 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. Bi-Blade - Bausch Surgical Effective cut rate.2. Highlights. 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. Vitreous surrogates were filed in borosilicate open beaker glasses centered on a microbalance (SBS-LW-2000A, Steinbers System, Germany). })(); I have read and agree to the privacy policy, Here you can put in a small abstract. In addition, fragmatomes have a significantly larger diameter and lumen, with even higher aspiration flow than provided by small-gauge infusion cannulas. In addition, high-speed videos of the vitrector during a duty cycle were recorded to differentiate the characteristics of each vitrectomy system. Pavlidis M. Two-dimensional cutting (TDC) vitrectome: in vitro flow assessment and prospective clinical study evaluating core vitrectomy efficiency versus standard vitrectome. Because there is no cutting blade that closes the opening of the port, aspiration is continuous while the ultrasonic movement is shearing vitreous fibers. Here, no significant differences (p>0.05) were seen for high cut rates compared to 0cpm. 1994;31(4):32738. Unlike the Akreos AO60 lens, this hydrophobic, aspheric, acrylic lens has the benefit of avoiding opacification under gas or oil following DSAEK or vitreoretinal procedures. UD interpretation of data, substantively revised the work. These two cases span a spectrum from the simple to the complex and demonstrate the flexibility of the Vitesse Hypersonic Vitrectomy technology (Bausch + Lomb). Retina. When performing posterior lensectomy, surgeons must alternate between using a vitreous cutter to remove vitreous and a fragmatome ultrasonic handpiece to remove lens material. 2 For EVA, at least at 6000cpm, significantly more vitreous (p<0.01) was aspirated using its dual-bladed compared to its mono-bladed probe. Pig vitreous gel: macromolecular composition with particular reference to hyaluronan-binding proteoglycans. Except for EVA, high cut rates adversely affect vitreous removal. Viscosity (mPa s) of egg white and Pluronic F127 in concentrations of 15% to 18% as a function of temperature (C). 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'. 1971;75(4):81320. Therefore, anterior segments of porcine eyes were removed, and vitrectomies were filmed under illumination (Multied LT-V8-15, Optronics, Germany). 2018, the year our new liquefaction technology for vitreous removal has been introduced onto the market. 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. A novel development is the Ultravit High Speed Vitrectomy Probe (Constellation Vision System, Alcon) which operates the vitrector blades by bidirectional pulsed air in contrast to the current spring release mechanism [14, 15]. The hypersonic system enabled us to perform safe vitrectomy whenever vitreous came to the port, even when engaging dense lens material (Figure 4). While single-port cutters cut only in the forward direction, Bi-Blade cutters dual-edge blade cuts in both the forward and backward directions, enabling two cuts per cycle. In addition, no significant differences for the aspirated mass at low vs high cut-rates were detected. Porcine eyes were obtained from a local slaughterhouse in order to use their vitreous within 12h of slaughter. Featured Category.

Bausch & Lomb Storz Ophthalmic Instruments. For all vitreous surrogates, EVAs double-bladed probe aspirated significantly (p<0.001) more vitreous than its mono-bladed probe. Figure 4. This can be an added benefit of the hypersonic vitrectomy system over the standard guillotine cutter systems. 2012;2012:148039. The flow rates decrease more or less with increasing cut rates, depending on the cutter system (spring- pneumatic duty cycle). Article Stanga, P. E., Pastor-Idoate, S., Zambrano, I., Carlin, P. & McLeod, D. Performance analysis of a new hypersonic vitrector system. Tap water, Pluronic-F127 gel (Pluronic-F127, Sigma-Aldrich, Germany), egg white and porcine vitreous were employed as substitutes of human vitreous. The eye in this surgery had undergone attempted cataract surgery for a hypermature cataract that had become complicated by a capsular rupture and dropped nucleus. This site is intended for Healthcare Professionals in EMEA only, jose Removal of lens material with the smaller opening of the hypersonic vitrectomy probe avoids this scenario of intraoperative transient hypotonous collapse of the globe. This case demonstrates how the Vitesse system can be utilized for removal of dense lens material without the typical fragmatome. The main issue has revolved around how to transform the probe vibration energy into a suitable system that can shear vitreous collagen fibers. A closed surgical system with valved trocar cannulas during simulated vitrectomy. volume7, Articlenumber:8 (2021) Trans Am Acad Ophthalmol Otolaryngol. The new probe joins the available 25- and 27-gauge Bi-Blade cutters as options in the Bi-Blade portfolio. Abulon DJ. The systems EVA (DORC), Constellation Vision System (ALCON), megaTRON S4HPS (Geuder) and Stellaris PC (Bausch and Lomb) were used. Cookies policy. Featured Product. More recently, 27-gauge instruments have shown encouraging results.1The thinner instrument can be safely introduced into smaller spaces between membranes and retina, serving as a multifunctional device and facilitating tissue dissection.1Furthermore, vitrectomy instruments with smaller gauge are better suited to the narrower spaces of pediatric eyes.2, On the other hand, aspiration rate produced by smaller-gauge vitreous cutters is proportionally decreased due to a reduced port size and smaller diameter and needs higher infusion and aspiration pressures to remove vitreous. Clinical Experiences With a New Vitrectomy System Consequently, porcine vitreous shows a comparable viscosity and viscoelastic behavior to human vitreous [21, 22]. 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. It provides capabilities for phacoemulsification, irrigation/aspiration, bipolar coagulation, and vitrectomy operations. 2016;2016:3849316.
