[Dry transconjunctival sutureless 25-gauge vitrectomy in the treatment of pediatric cataract].
Posterior capsule opacification is the most frequent complication of pediatric cataract surgery. To prevent posterior capsule opacification, primary phacoemulsification, posterior capsulotomy and anterior vitrectomy with intraocular lens implantation is the preferred method in the treatment of pediatric cataract. Anterior vitrectomy cutter, with 18-gauge, maximum frequency at 600/min and has simultaneous cutting, irrigation and aspiration functions, is associated with more complications and poor outcomes. In 20-gauge surgery, pars plana vitrectomy is performed with two-port sclerotomy. The irrigation increases movement of vitreous and 20-gauge sclerotomy needs suture for closing. In 25-gauge surgery, the vitreous cutter can be introduced into the vitreous cavity directly though conjunctiva and sclera. The stab incision is roughly half the size of 20-gauge cutter, therefore, the sclerotomy incision can be left unsutured. Surgery with dry transconjunctival sutureless 25-gauge vitrectomy may decrease the requirement for secondary membrane surgery and the risk for retinal detachment. The application of dry transconjunctival sutureless 25-gauge vitrectomy in the treatment of pediatric cataract is reviewed.
