摘要

AIM: To compare the effectiveness and safety of pars plana capsulotomy and vitrectomy using 25-gauge tansconjunctival sutureless vitrectomy system and 20-gauge vitrectomy system for posterior capsule opacification(PCO) in pseudophakic children.· METHODS: Retrospectively study. Pars plana capsulotomy and vitrectomy using 25-gauge sutureless vitrectomy system was performed for PCO in the study group(32 eyes). Patients in the control group(34 eyes)underwent capsulotomy and vitrectomy using standard20-gauge vitrectomy system, providing a comparison between 2 groups with regard to preoperative and postoperative best corrected visual acuity(BCVA),intraocular pressure(IOP), and intraoperative and postoperative complications. The two groups were performed consequentially. The patients ages ranged from 2 to 13y(means: 6.61 ±2.73y). Surgical technique,intraoperative and postoperative complications, visual acuity, IOP, and recurrent PCO were recorded.· RESULTS: The surgical procedure was performed uneventfully in all patients. Visual acuity improved significantly in both groups. BCVA improved in 22 eyes(81.5%) in the study group and in 28 eyes(87.5%) in the control group. There was no statistical difference of visual acuity that were attainable in two groups(H=0.115,P =0.909). Mean postoperative IOP showed no significant difference between the groups at 1wk. All sort of PCO were accomplished by 20-gauge system, while 25-gauge system was effective for pearls style and 2 grade of fibrous PCO, and was insufficient to grade 3 of PCO. In the study group two cases were not accomplished by 25-gauge system while 20-gauge system conqueredthem. Compared with the control group, mean operative time for opening and closing the sclerotomy in the study group was considerably reduced. The mean follow-up was 38.2mo(range: 8-79mo). During the follow-up period, no incision leakage, corneal edema, vitreous loss,IOL damage, retinal detachment, recurrent PCO, or other complications were noted.·CONCLUSION: Pars plana capsulotomy and vitrectom
