Primary posterior capsulotomy using a 25-gauge vitreous cutter in vitrectomy combined with cataract surgery.

We describe a primary posterior capsulotomy technique using a 25-gauge vitreous cutter to prevent postoperative posterior capsule opacification (PCO) in patients with vitreoretinal diseases who must have a vitrectomy combined with cataract surgery. Following phacoemulsification, a 25-gauge vitrectomy, and intraocular lens implantation in the capsular bag, the posterior capsule is removed via a pars plana approach using a 25-gauge vitreous cutter; the removed capsule is round, well centered, and approximately 5.0 mm in diameter. This technique prevents postoperative PCO completely, improving vision and enabling detailed examination of the fundus after surgery.
