ABSTRACT: •
Both 25- and 23-gauge sutureless vitrectomy techniques decrease surgical trauma and improve patients’ postoperative comfort.
•
The disadvantages of the 25-gauge system, however, include pliable instruments and slower gel removal time.
•
The 23-gauge system provides faster speed of vitrectomy and the instruments have stiffer shafts, but it requires a larger
incision.
•
Therefore 25-gauge is suitable in macular surgery and for less complex cases, while 23-gauge allows the performance of complex
retinal detachment. Patients suffering from more severe pathologies with poor visual recovery are still managed with 20-gauge
technology.

ABSTRACT: •
Sub-tenon anesthesia can be performed in order to perform small-gauge vitrectomy with less invasive modality than peribulbar
needle injection, and is more efficient than topical anesthesia as it allows akinesia as well.
•
Hypotony is a complication related to postoperative wound leakage, so incision construction is critical.
•
Oblique parallel incisions achieve airtight sclerotomies in 25- and in 23-gauge vitrectomy.
•
Shaving the cannula from the inside and removing the cannulas with low IOP pressure using a fiberlight are mandatory to avoid
vitreous incarcerations.
•
Endophthalmitis risk is greater in 25-gauge vitrectomy than in 25-gauge, and can be avoided by performing careful patient
preparation, by modifying incision construction, and by avoiding vitreous incarceration in the sclerotomies.
