DORC EVA PDF

CE mark was obtained in December and the enhancement is already in clinical use at several sites in Europe. From March the enhancement will be implemented in all new EVA systems and the enhancements can also be retro-fitted to all existing EVA posterior and combined systems subject to regulatory clearance per market. The enhancement has been developed in close collaboration with users, it delivers both OR efficiency and surgical performance enhancements to users. The benefits of the enhancement include the following. Firstly, the EVA footswitch has been completely redesigned, control of the EVA endolaser is now integrated into the main footswitch providing seamless switching between vitrectomy to laser and eliminating the need for a secondary laser pedal. As well as improving efficiency, any surgeon can operate independent of tech support when switching to laser.

We have had the EVA vitrectomy system DORC in our practice for roughly 3 months at the time of this writing, and we have learned a lot about the machine, including ways to modify it to maximize its efficiency. A complete core vitrectomy with the gauge system and TDC technology takes an average of 3 to 4 minutes. Given this improvement in efficiency, we have been doing significantly more gauge surgeries with this system. The time to complete a core vitrectomy with the gauge TDC platform comes close to that of a standard gauge procedure with a non-TDC vitrectome.

We have found that using gauge instruments requires much less adjustment than initially predicted. As is common with small-gauge surgery, we had an issue with some of the gauge instruments bending, but we resolved the problem with minor adjustments, such as small changes in hand position and the use of a finger on the shaft of the instrument to stabilize it.

The limiting factor in converting more cases to gauge is the finite number of options for forceps, scissors, and other instruments for the gauge ports. Although gauge forceps are evolving, they are not quite as good as our current and gauge forceps. This is more evident when teaching fellows to peel the ILM and ERM, as they have a harder time learning a new skill with more flexible instrumentation.

Our solution has been the use of a hybrid system with two gauge ports for the infusion and the light pipe and one gauge port for the dominant hand Video 1; eyetube. With the gauge port we are able to use the gauge cutter that comes in the pack to perform the vitrectomy, but we can also peel using our standard gauge instruments.

The company has stated that it plans to create hybrid packs to fit this model in the future. This will allow us to open a single pack of trocars, so as not to make the hybrid system cost-prohibitive.

VacuFlow VTi delivers the necessary flow and vacuum without risk of unwanted pulsation or flow. The EVA software allows the user to create multiple presets, which can be toggled through using the footpedal. We have used the different settings to perform entire vitrectomies for retinal detachments safely and efficiently, all on flow mode.

This setting allows us to move the cutter right up to the retinal surface with minimal movement of the detached retina. The EVA software is simple to use, includes voice feedback, and features easy-to-understand graphics on a inch touch screen.

Our surgical staff had little difficulty adjusting to the software and was comfortable using it after just a few cases. Additionally, it is easy to program and toggle between unique surgeon settings, such as those described above with regard to multiple flow control settings.

The EVA vitrectomy system comes with an integrated nm laser tool, which we find offers consistent operation. The settings for the laser are easy to adjust, and the machine includes a wireless laser pedal that can be moved around using a toe hole in the supporting safety guard without having to rely on the circulator.

The pedal includes integrated buttons that the surgeon can use to modify the power settings. The EVA also has a setting that allows an indirect laser to be plugged in. This is convenient because it eliminates having to purchase a second laser for the indirect in the OR. This allows surgeons to vary not only the light intensity, but also the color of the light from white to yellow.

Some surgeons find operating under gas easier while using a yellow light, but we prefer the white setting for all cases. When we first began using the EVA, we found that, in some cases, the vitrectomy was not as efficient as predicted. We learned later that the machine was primed in a non-TDC cutting setting, thus diminishing the efficiency of the cutter. The TDC cutter is quite efficient, and it is therefore important to keep an eye on the infusion because the port is always open on the cutter.

This might lead to using more balanced salt solution than one has used previously; however, it has not been an issue for us. Although we have had the EVA at our surgery center for only a little more than 3 months, we find that it has significantly increased our efficiency and safety in the OR, thanks to the fluidics of the TDC cutter.

We have used the EVA in more than cases and we will continue to add to that number with this gauge platform. We also look forward to more innovative features in terms of hardware and software.

Getting Familiar With EVA

The enhancements has been developed in close collaboration with surgeons and deliver both OR efficiency and surgical performance to users, according to a company news release. First, the EVA footswitch has been completely redesigned. Control of the EVA endolaser is now integrated into the main footswitch providing seamless switching between vitrectomy to laser, and eliminating the need for a secondary laser pedal. In addition to improving efficiency, any surgeon can operate independent of tech support when switching to laser, according to DORC.
