To describe a new surgical technique for making 23G and 25G transconjunctival sutureless vitrectomy (TSV) sclerotomies and placing trocars with minimal mechanical pressure to pars plana.
In this study patients undergoing vitreoretinal surgery a novel technique of making the trocar entries was use.We divide patients in 3 groups; in group 1, conventional entry was perform and use as control, in group 2 a no.11 scapel knife was introduce in pars plana for the sclerotomy incision, and in group 3, trocar insicion was made with a sharp diamond knife use in cataract surgery (side port in phacoemulsification). In 3 groups water tigth clousure was analyze at day one, 1 week and 1 month after surgery. Complete biomicroscopy, intraocular pressure and anterior segment optical coherence tomography were perform in every visit.
Safe, water tigth incisions were documented in all cases. When performing these novel maneuver we notice minimal resistance and strength needed to introduce the trocars, with excellent maneuverability and subsequent tigthness and no leaking after finishing the case.
These 2 novel techniques in performing sclerotomies in transconjunctival sutureless small gauge vitrectomy its a safe procedure, and it is superior to conventional technique when using resterilized material.
This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.
