A NEW SELF-SEALING CANNULA SYSTEM FOR 20-GAUGE VTTRECTOMY: OUTCOMES OF 247 CONSECUTIVE CASES

摘要

The development of 25-gauge and 23-gauge instruments has facilitated use of transconjunctival suture-less vitrectomy in complex surgical cases such as proliferative vitreoretinopathy and proliferative diabetic retinopathy. Some surgeons have proposed that transconjunctival sutureless vitrectomy can be adapted for all vitrectomy cases. However, 20-gauge conventional vitrectomy is still useful for selected severe cases. In particular, transconjunctival sutureless vitrectomy is not suitable for cases that need scleral buckling or use of strongly curved intraocular instruments. Therefore, we thought it was necessary to improve the safety of 20-gauge vitrectomy.
