Pump, Vacuum, Infusion and Intraocular Pressure Control in Vitrectomy Devices

Abstract

In vitrectomy devices pump, vacuum, intraocular pressure control and infusion systems must be in a delicate balance for optimal surgical results. In parallel with the advances in technology, there have been significant developments in pump and infusion systems in devices. The devices with only peristaltic or venturi pumps in conventional devices have been replaced by hybrid systems where both pumps are in the same device and can be easily switched between pumps during surgery. Likewise, gravity-dependent infusion systems have been replaced by automated systems that allow more controlled operation. These developments have allowed faster, safer and more comfortable surgery. In terms of finding the device that surgeons can work comfortably with, it is important to know the advantages and disadvantages of each vitrectomy device and to have information about these systems, which we will describe in our review.
