Of these small gauge instruments, one is an infusion port to resupply a saline solution and maintain the pressure of the eye, the second is a fiber optic light source, and the third is a vitrector. The vitrector has a reciprocating cutting tip attached to a suction device. This design reduces traction on the retina via the vitreous material. A variant sutureless, self-sealing technique is sometimes used.

Like most invasive surgical procedures, however, vitrectomy carries a risk of complications,<ref>{{cite web |url=http://nei.nih.gov/health/floaters/floaters.asp |title=Facts About Floaters |work=nih.gov |url-status=dead |archive-url=https://web.archive.org/web/20131207084700/http://www.nei.nih.gov/health/floaters/floaters.asp |archive-date=2013-12-07 }}</ref> including: retinal detachment, anterior vitreous detachment and macular edema – which can threaten vision or worsen existing floaters (in the case of retinal detachment).
