“The device reduces or eliminates the need to remove and wipe forceps. “I find the MVP to be more stable device and less fatiguing, in that there is no need to activate forceps with my hand,” he said. No iatrogenic retinal breaks or other complications were observed.īased on the device’s performance, Dr. In only 10 of the 100 cases, an instrument exchange was needed to wipe a fragment of a membrane that clogged the port of the device. The 25-gauge model was used in most cases 3 cases each were performed using the 23- and 27-gauge models. However, he has also used the MVP for more complicated cases such as diabetic traction detachment, myopic retinal detachment, and proliferative vitreoretinopathy retinal detachment. Awh has used the MVP in more than 100 cases, the majority of which were performed to treat ERMs or macular holes. He used the MVP to perform the fluid-air exchange in the macular hole case, eliminating the need for a separate extrusion cannula. Awh showed surgical videos of the MVP in cases of epiretinal membrane, macular hole, and traction retinal detachment. Two micropicks, one on each side of the tip, can be used to create an edge or flap in the membranes, and importantly, this is done with minimal risk of damaging the underlying retina.ĭr. It is small enough to create vacuum holding force but is sufficiently large enough to allow pieces of membranes to be aspirated out of the eye through the lumen of the MVP. The spatula shields the retina from the vacuum port, which is located much closer to the tip than the port of a vitrectomy cutter. Awh, who is in private practice at Tennessee Retina in Nashville, TN.Īt the distal end of the MVP is smooth primary spatula that is designed to lift membranes but not shred them. “The MVP is a multi-function device with active aspiration controlled by a foot pedal, using the active extrusion function of a vitrectomy machine,” said Dr. The device is available with 23-, 25- and 27-gauge shafts. With all of these capabilities, the number of instrument exchanges decreases, its use may eliminate the need for forceps and scrapers, and it may even cause less trauma to the macula. Awh designed the device, which can be used to create a membrane edge, secure the membrane, peel it from the retina, and remove it without removing the instrument from the eye fluid-air exchange can also be performed when needed. A new device for peeling internal limiting membranes (ILMs) and epiretinal membranes (ERMs) provides vitreoretinal surgeons an alternative to forceps during vitreoretinal surgeries.ĭuring the opening day of the American Academy of Ophthalmology’s virtual 2020 annual meeting, Carl Awh, MD, highlighted the Micro-Vacuum Pick (MVP) (Katalyst Surgical).
