Patients with a diagnosis at baseline of glaucoma, asteroid hyalosis, acute or chronic uveitis, or trauma were excluded. Developments in vitrectomy probe technology have accelerated in recent years, designed to improve intraoperative surgical control and allow dlrc core vitrectomy bulk vitreous removal and tractionless controlled vitreous shaving.

A principal goal in PPV is to minimize vitreous traction by removing only the target ocular tissue, without zssociate drawing unwanted tissue into the vitrectomy probe port or creating distant traction that might cause iatrogenic retinal tears or other complications.

When the vacuum level was constant, 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. Early gauge vitrectomy systems were marked by reduced fluid flow and longer vitrectomy duration compared with gauge systems [ 9 ].

Owing to the increased cutting and snipping capacity, the surgical intervention can be aszociate and, moreover, the traction exerted on the ocular tissue drawn in during the aspiration assoviate decreases while the suction flow increases. Nearly two decades on, it was suggested that a dual port vitreous cutter system might allow surgeons to perform bulk vitrectomy more efficiently [ 5 ]. Trending in Retina Powered by: A total of 80 patients were enrolled, with equal numbers, or 20 eyes, randomly allocated to one of four surgical treatment groups: Performance of the new generation 600 and gauge TDC vitrectomes was analyzed relative to the current generation or standard gauge and gauge cutter.

Findings from this small comparative case series assessment are supportive of the efficiency of TDC vitrectome technology and of faster cut speeds for vitrectomy surgery. Reported findings suggest that a TDC vitrectomy probe provides greater operating efficiency than conventional vitreous cutter instrumentation during sutureless small-gauge vitrectomy. A TDC vitrectome delivered good overall stability in aspiration flow rate that is independent of cut speed. Vitrectomy surgery using a TDC vitrectome resulted in faster core vitrectomy, a finding that was consistent across both gauge and gauge instrumentation surgery groups.


However, enlarging dorrc port diameter of a vitreous cutter to increase flow becomes less effective as the port becomes larger [ droc ]. Evaluations reported herein are nonetheless limited by small research scale drc by the fact that the same surgeon performed all vitrectomies in this single-centre clinical assessment. A prospective single-centre clinical study assessed duration of core vitrectomy procedure using a TDC vitrectome versus a standard single-cut rorc vitrectome; the results reveal shorter operating times using a double-cutting TDC vitrectomy probe.

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 vitrectome in patients undergoing vitrectomy for epiretinal membranes. The study adhered to the tenets of the Declaration of Helsinki, and local regulatory requirements were fulfilled.

Although great care is taken to ensure that all information is accurate, it is recommended that readers seek independent verification of advice on drugs and other product usage, surgical techniques and clinical processes prior to their use.

However, the design of new generation dual-opening vitreous cutters effectively overcomes these initial limitations by assoclate for consistent flow irrespective of the cut rate used during vitrectomy surgery.

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.

The concept of a double-cutting instrument for use in ophthalmic surgery was first sssociate in [ 4 ].

Aspiration flow rates remained constant independent of TDC vitrectome cut rate, while flow rates decreased linearly at higher cutter speeds using a classic single-blade vitrectome. 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 Associaet vitrectome technology for faster, less turbulent, and potentially safer smaller-gauge vitrectomy.

Inclusion criteria were chosen to ensure adherence to a similarity principle, with similar vitreous liquefaction, similar case duration 600 difficulty, similar vitreous volume, and similar overall ocular conditions having had no prior ocular surgical intervention. Indexed in Science Citation Index Expanded.

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

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.

The concept of a double-action surgical cutting probe has only recently been developed and incorporated into modern vitrectomy instrumentation probes that feature 2 cutter openings in the guillotine shaft, thereby performing a vitreous cutting action on both forward and backward stroke of the probe device. Retinal traction increases with increasing aspiration vacuum and proximity to the retina and decreases with higher cut rates [ 1 ].

At-a-Glance Dual system, phaco and vitrectomy Twin pump system, peristaltic and venturi Programmable dual linear footswitch. The idea involved inclusion of an opening in the internal guillotine pipe or inner vitrectome sleeve.

To evaluate comparative aspiration flow performance and also vitrectomy associatee time efficiency using a double-cutting open port vitreous cutting system incorporated in a two-dimensional cutting TDC, DORC International vitrectome design versus standard vitreous cutter. The inner tube has been designed with a rectangular aperture for increased and continuous flow functionality.

In the author in wssociate 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 enhanced intraoperative fluidics stability.

Future follow-up studies might usefully evaluate postoperative visual, anatomic, and safety outcomes.
