New-generation cannula overcomes fluidic challenges of small-gauge vitrectomy surgery

NICE, France — A new-generation cannula with a closed tip and four vent ports along the tube improves safety and efficiency regarding injection of perfluorocarbon liquids, staining dyes or other fluids during small-gauge vitrectomy surgery, according to one speaker. With the advent of microincision vitrectomy surgery, the 20-gauge cannula has been scaled down to 23 gauge, 25 gauge and 27 gauge.
