LAUSR

The use of hybrid limbal based vitrectomy for ROP is not previously reported in the literature. In our technique, all working ports are made in the clear cornea, thus, eliminating any chances of creating inadvertent retinal breaks. We prefer a 23G MVR blade (0.6 mm) that creates flat corneal openings which provide enough space for inserting 25G instruments and yet snug fit for adequate maintenance of the anterior chamber and proper infusion fixation. The corneal MVR allows a much sharper, flatter, self-sealing corneal entry compared to direct trocar cannula entries, which are a little difficult to insert in the cornea, as they are not designed for corneal entry and hence mostly need suturing as well. Corneal wrinkling may occur during instrument manipulation from corneal incisions (which may lead to poor surgical view); however, this is minimized significantly by proper incision orientation as well as use of contact lens which helps to provide an excellent view.
