Ultrasonic vitrectomy has been attempted in the past, but there have been difficulties in performing it reliably. Transconjunctival sutureless 23-gauge vitrectomy. Aside from the further miniaturization of the scleral incision to mitigate trauma of the surgical procedure, a primary goal of recent vitreoretinal research is to increase the efficiency of the vitrectomy. window.mc4wp.listeners.push({ In addition, fragmatomes have a significantly larger diameter and lumen, with even higher aspiration flow than provided by small-gauge infusion cannulas. Bausch + Lomb, BL3190, Bausch + Lomb Anterior Vitrectomy A - eSutures Furthermore, we are grateful for the funding from the German Federal Ministry of Education and Research (BMBF) (Grant 13GW0051C). The handpiece aspirates at a controlled vacuum through the opening at its tip. 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. 2013;229(1):1520. For EVA, at least at 6000cpm, significantly more vitreous (p<0.01) was aspirated using its dual-bladed compared to its mono-bladed probe. Comparable results are shown for Stellaris PC (20G, p<0.001, 23G, p<0.05) for cut rates at and above 3000cpm compared to 0cpm. Though this concept was similar to flow-based systems, Moore sees it as a key distinction. Intraocular lenses, monofocal and premium. Both videos were recorded at 5000cpm and 200mmHg aspiration pressure. Nevertheless, the area under the curve analysis (Fig. The other new feature on the DAISY was an ultrasound handpiece that ran at a frequency of 28 kHz versus the higher frequencies used by other units. Fang, S. Y., DeBoer, C. M. T. & Humayun, M. S. Performance analysis of new-generation vitreous cutters. control 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. 1975;53(5):7317. Clin Exp Ophthalmol. Stellaris Elite - Bausch Surgical 2010;117:18893. } BL3190: Bausch + Lomb Anterior Vitrectomy Adapter Kit. 15243 Given the similarities between water and Pluronic gel regarding their homogeneity, further experiments were not performed on Pluronic gel. The technological advances in surgical devices have allowed not only increased surgical efficiency but also broaden the repertoire of indications. It could be shown that water and biological gels substantially differ from one another. The datasets analyzed during the current study are available from the corresponding author on reasonable request. Coburns New Visual Field Analyzer and Retinal Camera. A Convenient Solution for Office Injections. Machemer R, Buettner H, Norton EW, Parel JM. 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. Ann Ophthalmol. 6). Furthermore, the high flow of the fragmatome can aspirate vitreous fibers inadvertently and potentially cause retinal traction and tears. For all vitreous surrogates, EVAs double-bladed probe aspirated significantly (p<0.001) more vitreous than its mono-bladed probe. Tractional Retinal Detachments, J. Daniel Diaz, MD Justin H. Townsend, MD, Editorially Independent Content, Supported With Advertising from Bausch + Lomb and NIDEK, July/August 2021 Supplement | Clinical Case Compendium, Watch all complex surgical case videos at eyetube.net/editorial-feature/retina-clinical-case-compendium-2021. Bausch + Lomb Surgical/Vision Care. Porcine eyes were obtained from a local slaughterhouse in order to use their vitreous within 12h of slaughter. Biochimie. There was constant aspiration even at higher cut rates which, again, became significant only for EVA at 6000cpm, presumably based on high standard deviations for the other experiments. Magalhes O Jr, Maia M, Maia A, Penha F, Dib E, Farah ME, Schor P. Fluid dynamics in three 25-gauge vitrectomy systems: principles for use in vitreoretinal surgery. 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.

Poster presentation at ARVO annual meeting 2012;abstra #D972. 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. Repairs 2023 Bausch & Lomb Incorporated. Cut rates were varied in increments of 1000 cuts/min from 500cpm to the systems maximum and vacuum pressures were varied in increments of 100mmHg, from 100 to 600mmHg up to the individual systems maximum. We chose 20G and 23G probes, since not all systems had switched to a smaller G at the time the study was conducted in 2016. 2012;2012:148039. })(); I have read and agree to the privacy policy, Here you can put in a small abstract. This decreased the possibility of vitreous traction, which may occur when using a typical fragmatome handpiece and vitreous approaches the tip. By considering its higher viscosity, less Pluronic gel was aspirated than water. Additionally, the newly developed twin duty cycle (TDC) cutters in the EVA system and Mach2 in megaTRON S4HPS systems were tested, all of which operate with double-bladed cutters. Highlights. No Comments. Despite the size, there are differences in the efficiency of vitrectomy depending on the vitrectomy system used. Vitreous surrogates were filed in borosilicate open beaker glasses centered on a microbalance (SBS-LW-2000A, Steinbers System, Germany). 2016;44(4):34054. on: function (event, callback) { News Release 1 MID Labs Vitreoretinal Ophthalmic Medical Devices. Trans Am Acad Ophthalmol Otolaryngol. Proprietary color filters deliver distinctadvantages over systems without filters and may be used as an augmentation or an alternative to intraoperative dyes. Hypersonic vitrectomy rests on the well-utilized physics of ultrasound probes for intraocular surgery. 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 device features an auto mosaic. Experience the stability and efficiency of dual-port cutting with Bi-Blade vitrectomy cutters for the Stellaris Elite platform. Peripheral vitrectomy with the hypersonic system (Figure2) may be safer than standard guillotine cutter vitrectomy, because non-pulsatile linear flow decreases peripheral retinal traction caused by intermittent tugging of the peripheral vitreous typical of guillotine cutters. RD interpretation of data, substantial contributions to the conception, drafted the work and substantively revised it. The patient was referred to us with an edematous cornea and retained dense nuclear and epinuclear fragments.

A revolutionary approach to vitreous removal. Article 21 North Park Place. The rotation viscometer measures the force needed to rotate a spindle submerged in the substance. The dual-port design ofBiBlade greatly enhances efficiency due to the unique design that allows for cutting without port closure. Magalhaes O Jr, Chong L, DeBoer C, Bhadri P, Kerns R, Barnes A, Fang S, Schor P, Humayun M. Guillotine performance: duty cycle analysis of vitrectomy 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. However, we could not demonstrate differences between vitreo-retinal interactions depending on the vitrectomy system used. The main issue has revolved around how to transform the probe vibration energy into a suitable system that can shear vitreous collagen fibers. 1972;10:6849. With built-in abilities to seamlessly handle future updates and enhancements, Stellaris Elite is optimized to provide value for multi-use environments now and as future practice needs arise. 7) indicates some decline or a slower increase of aspirated mass with increasing cut rates for some systems. Bausch + Lomb also announced the introduction of the 23-gauge Bi-Blade dual port vitrectomy cutter for the Stellaris Elite vision enhancement system.
