The TDC vitrectome comprises a tubular outer part and an axially movable tubular inner part arranged in the outer part [ 7 ].

The artificial vitreous, consisting of a mixture of deionized water, agar, and hyaluronic acid sodium salt, was produced according to a protocol published by Associatr et al. View at Google Scholar F. Nearly two decades on, it was suggested that a dual port vitreous cutter system might allow surgeons to perform bulk vitrectomy more efficiently [ 5 ].

The second cutting movement is realized through cooperation of the distal cutting edge of the inner part with the proximal cutting edge of the outer part. Overall, vitrectomy case duration using a TDC vitrectome in combination with the EVA surgical machine was shorter than vitrectomy operating time using a standard or classic single-cut asscoiate in patients undergoing vitrectomy for epiretinal membranes.

Max Cut Speed cpm.

In vitro investigations compared aspiration flow rates in artificial vitreous humor at varying cutter speeds and vacuum levels using a TDC vitrectome and a standard vitrectome across different aspiration pump systems. Retinal surgeons associste high vitreous cutter rates so as to maximize fluidic stability and reduce unwanted force or traction.

Table of Contents Alerts. Initially, these tests were performed with water. Figure 1 illustrates core design elements aasociate a TDC vitrectome and a classic single-cut vitrectome. The axial position of the distal cutting edge of the inner part as a function of the circumferential direction initially proceeds towards the proximal end and then back to the distal end again. To evaluate comparative aspiration flow performance and also vitrectomy operating time efficiency using a double-cutting open port vitreous cutting system incorporated in a two-dimensional cutting Dorcc, DORC International vitrectome design versus standard vitreous cutter.


This necessitates higher infusion and aspiration pressures to remove vitreous when using smaller-gauge vitrectomes.

During a cycle in which the inner part performs a back-and-forth movement in the outer part, a cutting movement occurs twice. The study adhered to the tenets of the Declaration of Helsinki, and local regulatory requirements were fulfilled.

Megatron Cool Geuder AG. The port diameter of this new TDC vitrectome is larger than previous vitrectome designs for the gauge TDC vitrectome, e. Early gauge vitrectomy systems were marked by reduced fluid flow and longer vitrectomy duration compared with gauge systems [ 9 ].

When the classic gauge vitrectome was connected to the Associate system, aspiration flow rate decreased from 1. Investigators found that, using modified gauge vitrectomy probes, the time of aspiration remained almost constant irrespective of cutting speed, indicating almost no reduction of flow but, more importantly, that aspiration time was significantly reduced compared with a standard single port cutter.

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

A standard blade vitrectome of both gauges was also evaluated for aspiration flow rate at varying cut rates when connected to an Associate machine.

Vitrectomy surgery using a TDC vitrectome resulted in faster core vitrectomy, a finding that was consistent across both gauge and gauge instrumentation surgery groups. Trending in Retina Powered by: Retinal traction increases with increasing aspiration vacuum and proximity to the retina and decreases with higher cut rates [ 1 ].

Advocates asskciate 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 ]. Asscoiate 2 tabulates the mean duration of core vitrectomy procedures for each surgical intervention group assessed.

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.


Experimental assessments show maintenance of constant high aspiration flow independent of cutter speed using a two-dimensional cutting TDC vitrectome for vitreous removal. Vitrectomy surgery performed using a TDC vitrectome was faster than core vitrectomy utilizing awsociate standard single-action vitrectome at similar cut speeds. Both parts have an opening in the tube, allowing continuous aspiration of tissue during a complete cutter cycle movement. A principal goal in PPV is to minimize vitreous traction by removing only the target ocular tissue, without inadvertently drawing unwanted tissue into the vitrectomy probe port or creating distant traction that might cause iatrogenic retinal asssociate or other complications.

Time measurement of core vitrectomy duration was made by a assocoate person without a need to change standard vitrectomy procedures of PPV for epiretinal membrane removal. The concept of a double-cutting instrument for use in ophthalmic surgery was first patented in [ 4 ]. If the higher double-cutting rate minimizes unwanted vitreous traction and reduces the risk of iatrogenic retinal damage is object of a safety designed ongoing study.

Asssociate Geuder AG. After activation of the vitreous cutter, a small time was allowed for attainment of a constant vacuum level in the aspiration tubing. 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. Performance of the new generation gauge and gauge TDC vitrectomes was analyzed relative to the current generation or standard gauge and gauge cutter.
