Abstract

As combined procedure with pars plana vitrectomy, pars plana lensectomy lowers the incidences of corneal edema and constriction of pupil, and elimi-nates the risk of corneal incision leakage.When intraocular lens is inserted, conventional procedure requires large anterior capsulectomy to prevent after-cataract.To maintain barrier between anterior and posterior seg-ments, anterior capsule was preserved and lens epithelial and cortical cells were polished off thoroughly with enhancement of visualization by intraocu-lar illuminator.Intraocular lenses were inserted into ciliary sulcus after vitrectomy.After a minimum of 1 year, postoperative vision was better in 17 of the 24 eyes (71%).the same in six eyes (25%)and worse in one eye (4%). Postoperative complications included after-cataract in 4 eyes (17%), decen-tration of intraocular lens in 2 eyes (8%), retinal detachment in 1 eye (4%) and neovascular glaucoma in 1 eye.Only two eyes required Nd:YAG laser capsulotomies. If intraocular illumination is utilized properly, lens epithelial and cortical cells can be removed thoroughly after pars plana lensectomy combined with vitrectomy and anterior capsule can be maintained without significant increase of after-cataract.
