A 27–Gauge Instrument System for Transconjunctival Sutureless Microincision Vitrectomy Surgery

Microincision cataract surgery combined with vitrectomy: a case series

“…In retinal surgery, transconjunctival 'sutureless' pars plana vitrectomy with 23-, 25-, and 27-G techniques have been described. [1][2][3] Likewise, microincision cataract surgery (MICS) can be achieved by sub-2 mm incisions. 4 The main advantages of MICS include minimising surgically induced astigmatism and reducing higher-order corneal aberrations.…”

“…15 Oshima et al introduced further miniaturisation of the technique by means of a 27G sutureless vitrectomy system. 16 …”

“…16 As the ports of 25G and 23G vitreous cutters are small and the distances from the ports to the tips shorter than those of a conventional 20G vitreous cutter, the cutters can serve as multifunctional tools during diabetic vitrectomy, being used as vitreoretinal scissors, forceps and backflush needle. 34 In their recent study, Oshima et al 35 developed several instruments for 27G PPV.…”

“…To minimise the flexibility, Oshima et al shortened the shaft of their vitrector from 32 mm to 25 mm. 16 In doing so, they produced a 27G vitrector with similar stiffness to the standard 25G vitrector. The authors contend that even with a shorter shaft length, they were able to perform core and peripheral PPV in eyes with axial lengths ranging from 22 mm to 28 mm.…”

“…16 The fiberoptic remains fixed to the sclera after insertion, enabling execution of bi-manual surgery and providing wide illumination of the vitreal cavity (a 'chandelier'-type illumination). There is also a Torpedo light for a chandelier effect.…”
