A recent publication in Clinical Ophthalmology highlights the time efficiency benefit and similar safety profile of the 27-gauge HYPERVIT dual-blade vitrectomy cutter when compared to the 27-gauge ADVANCED ULTRAVIT vitrectomy cutter. †
In this retrospective observational study of 40 eyes undergoing vitrectomy for the treatment of epiretinal membranes (ERM) with posterior vitreous detachment (PVD), 20 eyes underwent vitrectomy using the 27 gauge, 10,000 cuts per minute (CPM) ADVANCED ULTRAVIT vitrectomy cutter and another 20 eyes utilized the 27 gauge 20,000 CPM HYPERVIT dual-blade vitrectomy cutter. †
All surgeries were performed by a single retinal surgeon using 4 ports, with one of the ports dedicated to a chandelier illumination system to enhance illumination and visibility during surgery. The maximum cut rate was used for each vitrectomy cutter (20,000 CPM for HYPERVIT and 10,000 CPM for ADVANCED ULTRAVIT), with vacuum ranging between 0–650 mmHg; intraocular pressure (IOP) was set to 25 mmHg. †
Baseline characteristics were not significantly different between groups. Duration of vitrectomy, visual acuity, the need for scleral wound closure, changes in IOP as well as complications were measured. †
The duration of vitrectomy was significantly less in the HYPERVIT group (153 ± 40s) when compared to the ADVANCED ULTRAVIT group (184 ± 57s, p=0.047). However, there were no significant differences in visual acuity, changes in IOP or the need for scleral wound closure. Only one complication of vitreous hemorrhage was noted in the ADVANCED ULTRAVIT group. †
The authors concluded that there appeared to be a time efficiency benefit with HYPERVIT when compared to ADVANCED ULTRAVIT, while providing similar safety profiles. †
