We previously described a technique of dry pars plana posterior capsulotomy combined with anterior vitrectomy using a 25-gauge vitrectomy system after in-the-bag intraocular lens (IOL) implantation in paediatric cataract surgery.1 However, two eyes (2.5%) in the series suffered transient hypotony (<8 mm Hg), which was related to the vitrectomy incision. In our clinical practice afterwards, such a situation also occurred. Meanwhile, low cutter efficiency was noted in a few cases, which required over 60 s for posterior capsulotomy and vitrectomy with viscoelastic materials remaining in the capsular bag. Therefore, we tried to improve the technique, and report our further surgical experience herein.


A consecutive series of 57 patients (80 eyes) with paediatric cataract were included in this study. All children underwent anterior continuous curvilinear capsulorhexis, phacoemulsification and IOL (Akreos Adapt, Baush & Lomb, Rochester, New York, USA) implantation in the capsular bag through a 3.2 mm scleral incision. The …
