Purpose: An original, modified, transconjunctival, 2-step 23G trocar insertion technique is presented in this article.

Methods: The technique does not require the use of Eckard pressure plate for displacement of the conjunctiva and stabilization of the globe. The technique prevents disalignment of conjunctival and scleral aperture and consequent, possible loss of the sclerotomy under the conjunctiva.

Results: The advantage of this bimanual, modified technique is that an instrument is constantly engaging the sclerotomy: the bent MVR blade serves as guide for the microcannula-inserter assembly. The microcannula-inserter introduction without Eckardt pressure plate also allows a precise measurement of the distance of the sclerotomy site from limbus, and a customized construction of the scleral tunnel.

Conclusions: This modified 2-steps technique simplifies the introduction of 23 G cannulas in complicated situations, such as chemotic and/or haemorrhagic conjunctivas and already vitrectomized eyes.
