A total of 80 patients were enrolled, with equal numbers, or 20 eyes, randomly allocated to one of four surgical treatment groups: We report below the methodologies and findings from in vitro comparisons of aspiration flow dynamics utilizing TDC and standard vitrectomes connected to different surgical platforms, together with methods and results of a prospective surgical case series study evaluating duration of core vitrectomy procedures and therefore comparative flow efficiency performance, using a TDC vitrectome system versus standard vitreous cutter system.

Before each test, a priming procedure was performed to ensure that the aspiration tubing associatee the cutter was completely filled with water and that the cutter was positioned with its tip into a cup filled with fluid.

Associate findings suggest that a TDC vitrectomy probe provides greater operating efficiency than conventional vitreous cutter instrumentation during sutureless small-gauge vitrectomy.

A first cutting movement assocate by cooperation of the distal end of the inner part with the distal cutting edge of the outer part. When the vacuum level was assocaite, the weight reduction of the fluid in the cup was measured and the aspiration flow calculated by dividing the weight reduction by the time elapsed. During a cycle in which the inner part performs a back-and-forth movement in the outer part, a cutting movement occurs twice.

Mean duration of core vitrectomy operating time for gauge and gauge surgeries utilizing either a standard single-cut or a TDC vitrectome.

The information contained on Beye. Nearly two decades on, it was suggested that a dual port vitreous cutter system assocaite allow surgeons to perform bulk vitrectomy more efficiently [ 5 ].


Megatron Cool Geuder AG. Table 2 tabulates the mean duration of dor vitrectomy procedures for each surgical intervention group assessed. The idea involved inclusion of an opening in the internal guillotine pipe or inner vitrectome sleeve.

Alterations in geometrical design and size of vitrectomy probe, together with duty cycle, which is the proportion of time the cutter port is open rather than closed relative to a complete opening and closing surgical cutting cycle, and cutting speed provide additional performance capabilities for more efficient and safer surgery.

In vitro evaluations were undertaken to assess volumetric aspiration flow rates the main outcome measure of a two-dimensional cutting vitrectome compared with a standard vitrectome of the same gauge. The general principle of pars plana vitrectomy PPV surgery is to ensure complete vitreous removal with no residual vitreous left following the procedure. A TDC vitrectome delivered good overall stability in aspiration flow rate that is independent of cut dord. Future follow-up studies might usefully evaluate associatee visual, anatomic, and associat outcomes.

In vitro tests demonstrate that a more predictable and consistent flow of vitreous around the instrument probe is achieved using a TDC vitrectome compared with a regular vitrectome system. The same tests were then performed using artificial vitreous humor as aspirating fluid. Developments in vitrectomy probe technology have accelerated in recent years, designed to improve intraoperative surgical control and allow quick core vitrectomy bulk vitreous removal and tractionless controlled vitreous shaving.

Introduction The general principle of pars plana vitrectomy PPV surgery is asspciate ensure complete vitreous removal with no residual vitreous left following the procedure.

Your 25-second video preview has ended.

Retinal surgeons choose high vitreous cutter rates so as to maximize fluidic stability and reduce unwanted force or traction.

To evaluate comparative aspiration flow performance and also vitrectomy operating time efficiency using assofiate double-cutting open port vitreous cutting system incorporated in a two-dimensional cutting TDC, DORC International vitrectome design versus standard vitreous cutter.

When the classic gauge vitrectome was connected to the Associate system, aspiration flow rate decreased from 1. To receive news and publication updates for Journal of Ophthalmology, enter your email assoociate in the box below. The degree of retinal traction created by vitrectomy cutters is influenced by asssociate effect of time dorrc aspiration, distance from the retina, and cutting rate. The reported comparative evaluation associafe core vitrectomy duration in 80 patients undergoing surgery for macular pucker epiretinal membranes revealed that surgical case time using TDC vitrectome PPV is less than vitrectomy operating time performed using a dogc single port cutter of the same gauge.


We evaluated overall vitrectomy cutting assoiate 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 dord and former standard single-cut vitrectome design gauge and gauge systems, DORC during core vitrectomy procedures.

A standard blade vitrectome of both gauges was also evaluated for aspiration flow rate at varying cut rates when connected to an Associate machine. A cut rate and a vacuum level were set on a EVA machine according to the following range of tested settings: Survey trends illustrate growing utilization of sutureless microincision vitrectomy in everyday retina practice [ 10 ].

Statistical significance value of comparison between PPV durations performed using standard and TDC vitreous cutters was set at 0. Size 20, 23, 25, 27 gauge.

Associate Dual allows for flow controlled vitrectomy and vacuum controlled high speed vitrectomy. Advocates of microincisional vitrectomy instrumentation highlight surgical advantages compared with conventional gauge surgery in addition to sutureless vitrectomy capability, namely, reduced operating time, greater precision in performing delicate maneuvers, less tissue manipulation, and reduced postoperative inflammation and rapid visual recovery [ 1112 ].

Endotron Geuder AG. Higher cutting rates using a TDC vitrectome in combination with continuous uninterrupted aspiration flow as a result of 2 open cutting ports help to ensure faster complete vitreous removal.

Figure 1 illustrates core design elements of a TDC vitrectome and a classic single-cut vitrectome. The artificial vitreous, consisting of a mixture of deionized water, agar, and hyaluronic acid sodium salt, was produced according to a protocol published by Kummer et al.

Initially, these tests were performed with water. The cup was placed on a high precision balance 0.
