Pars Plana Lensectomy and Intraocular Lens Implantation in Pediatric Radiation-Induced Cataracts in Retinoblastoma

Pars plana lensectomy, vitrectomy, and simultaneous intraocular lens implantation is an effective means of managing EBRT-induced cataracts in eyes with previously treated RB. There was no evidence of active tumor in eyes undergoing surgery at least 28 months after the diagnosis and commencement of therapy for RB, and no late intraocular, orbital, or metastatic tumors were detected. Visual acuity was limited by the presence of primary macular tumor pathologic features in a subset of patients, but final vision better than 20/400 may be achieved in these eyes.
