Abstract The aim of this study is to describe and evaluate the surgical management of sublimated or dislocated crystalline lens in patients with complications of closed- globe injury using pars plana lensectomy, pars plana vitrectomy and scleral fixation of posterior chamber intraocular lens. The conclusion of this study is that combined lensectomy, pars plana vitrectomy and primary intraocular lens implantation, in the management of eyes with closed trauma with ectopia lentis, is safe, and allows rapid visual rehabilitation and saves the patient another surgery. Both scleral fixation of pc-iol and ac-iol can be used but since scleral-fixation of pc-iol is technically more difficult than ac-iol implantation, the decisive factor in choosing the iol is the ocular condition and the surgical experience. Scleral fixation of pc-iol is better in children, eyes with glaucoma or damage to the ac angle, eyes with peripheral anterior synhiae, or eyes with insufficient iris tissue to support ac-iol. Capsuaiar tension rings can be used in cases of traumatic subluxated lenses, without vitreous in the AC, to allow the implantation of a foldable pc iol in the capsular bag. The risk factors for decreased postoperative visual correction were the presence of preoperative post traumatic maculopathy, retinal detachment, glaucoma and amblyopia, and postoperative development of cystoids macular edema, epiretinal membrane and retinal detachment. |
