Higher cutting rates using a TDC vitrectome in combination with continuous uninterrupted aspiration flow as a result of 2 open cutting ports asxociate to ensure faster complete vitreous removal. This content is intended for health care professionals and providers only.

All vitrectomized subjects were adequately informed prior to surgery about standard PPV for epiretinal membrane and core vitrectomy measurements and signed a consent form.
When vitreous enters the inner aperture, it is cut first in a forward motion and then again during the backward motion.
Investigators found that, using modified gauge vitrectomy probes, the time of aspiration remained almost constant irrespective of cutting associxte, indicating almost no reduction of flow but, more importantly, that aspiration time was significantly reduced compared with a standard single port cutter.
The average aspiration flow was calculated by averaging the measurement results of the different trials and the different vitreous cutters 66000 the same type and gauge. There is undoubtedly a surgical learning curve involved in mastering the technique of using small-gauge vitrectomy instruments, typically involving the first 20 or so cases.

A TDC vitrectome delivered good overall stability in aspiration flow rate that is independent of cut speed. Company Information Contact the company for additional information, availability, or pricing: Retinal surgeons choose high vitreous cutter rates so as to maximize fluidic stability and reduce unwanted force or traction. For all tests performed, a density of 1. Moreover, the continuous open port of the TDC vitreous cutter permits greater tissue removal efficiency that is unaffected by cutter velocities, showing the potential of TDC vitrectome technology for faster, less turbulent, and potentially safer smaller-gauge vitrectomy.
In assoclate author in cooperation with DORC International developed a newer vitrectome design, introducing a modified vitreous cutter technology called two-dimensional cutting TDC vitrectome system, launched in conjunction with the EVA ophthalmic surgical platform, a new aspiration system designed to provide both flow and vacuum control mode vitrectomy for assoociate intraoperative fluidics stability.
A prospective single-centre clinical study evaluated duration of core vitrectomy in 80 patients with macular pucker undergoing gauge or gauge vitrectomy using either a TDC vitrectome at 16, cuts per minute cpm or standard single-cut vitrectome, combined with a Valve Timing intelligence VTi pump system EVA, DORC International.
The inner tube has been designed with a rectangular aperture for increased dprc continuous flow functionality. A first cutting movement occurs by cooperation of the distal end of the inner part with the distal cutting edge of the outer part.
A cut rate and a vacuum level were set on a EVA machine according to the following range of tested settings: Size 20, 23, 25, 27 gauge. The degree of retinal traction created by vitrectomy cutters is influenced by the effect of time associafe aspiration, distance from the retina, and cutting rate.
We evaluated overall vitrectomy cutting time in seconds required to remove core vitreous in 80 patients diagnosed with macular pucker as part of a comparative evaluation of flow and operating duration using a TDC vitrectome and former standard single-cut vitrectome design gauge and gauge systems, DORC during core vitrectomy procedures. A report by the American Academy of Ophthalmology in noted that, compared with gauge vitrectomy, small-gauge vitrectomy is associated with significantly lower levels of patient discomfort and ocular inflammation, with faster improvement in visual acuity, and an acceptably low incidence of adverse events comparable to those observed for gauge vitrectomy [ 13 ].
A standard blade vitrectome of both gauges was also evaluated for aspiration flow rate at varying cut rates when connected to an Associate machine. Introduction The general principle of pars qssociate vitrectomy PPV surgery is to ensure complete vitreous removal with no residual vitreous left following the procedure. The port diameter of this new TDC vitrectome is larger than previous vitrectome designs for the gauge TDC vitrectome, e.

Indexed in Science Citation Index Expanded. The concept of a double-cutting instrument for use in ophthalmic surgery was first patented in [ 4 ].
The TDC vitrectome comprises a tubular outer part and an axially movable tubular inner part arranged in the outer part [ 7 ]. Results suggest significantly decreased operating time for core vitrectomy.
Nearly two decades on, it was suggested that a dual port vitreous cutter system might allow surgeons to perform bulk vitrectomy more efficiently [ 5 associaet. Fluidic stability and control during vitrectomy is essential. The outer part has a closed distal end and the inner part an open distal end.
