Combined aniridia-intraocular lens implantation and pars plana vitrectomy in cases with total traumatic aniridia and retinal disordersB. Wiechens
Background: Total traumatic aniridia can complicate intraocular surgery. Especially in those cases with retinal diseases that demand a combined approach with pars-plana-vitrectomy (PPV) and intraocular tamponade the cornea can be impaired by the tamponade substances or gases.
Patients and methods: We present 3 cases with total traumatic aniridia in which implantation of an aniridia-IOL (desg. by Sundmacher) and combined PPV was performed for the following indications:
Results: Operative procedures could be performed without complications in all 3 cases. All eyes experienced postoperative increase in visual acuity. In the latter eye with silicone oil-tamponade the aniridia-IOL could prevent the silicone oil from overflow into the anterior chamber and corneal endothelial contact.
Conclusions: A combined aniridia-IOL-implantation and PPV is possible without intraoperative complications. In those cases that require intraocular silicone oil-tamponade the aniridia-IOL similar to the iris diaphragm developed by Heimann et al. - can prevent endothelial contact of the silicone oil. Is the visual prognosis favorable then implantation of this type of aniridia-IOL may be considered.
