1/5. cataract surgery combined with implantation of an artificial iris.We describe 6 patients who presented with cataract or aphakia and absent or nonfunctional irides. The etiologies included congenital aniridia, traumatic iris loss, and chronic mydriasis secondary to recurrent herpetic uveitis. In 5 eyes, a prosthetic iris was successfully implanted in combination with small incision cataract surgery. In 2 eyes, a single-piece iris diaphragm and optical lens was implanted. Artificial irides offer a safe alternative for patients who previously had no viable options for iris reconstruction.- - - - - - - - - - ranking = 1keywords = aphakia (Clic here for more details about this article) |
2/5. Black iris-diaphragm intraocular lens for aniridia and aphakia.We present the first reported use in the united states of a black iris-diaphragm intraocular lens (IOL) for the treatment of traumatic aniridia and aphakic bullous keratopathy. The patient presented to a university-based practice with contact-lens-intolerant aniridia and aphakia with painful bullous keratopathy from a failed corneal graft. He was treated with combined penetrating keratoplasty and transscleral fixation of an aniridia IOL. The patient's preoperative symptoms of debilitating glare and photophobia resolved substantially after surgery, despite mild postoperative inflammation that resolved. The symptoms associated with aniridia can be successfully treated with a black iris-diaphragm IOL; however, chronic low-grade inflammation has been reported with its use in some cases.- - - - - - - - - - ranking = 5keywords = aphakia (Clic here for more details about this article) |
3/5. Management of post-traumatic aniridia with retinal detachment.PURPOSE: To reconstruct the anatomic and functional impairment in patients with post-traumatic aniridia, aphakia, and retinal detachment. methods: Four patients with unilateral aniridia and aphakia as well as retinal detachment as results of severe eye injuries underwent scleral buckling, vitrectomy, membrane peeling, endolaser photocoagulation, silicone oil or gas temponade, combined with iris diaphragm-IOL implantation. RESULTS: All four patients achieved successfully anatomic and functional reconstruction after surgery. During five to 22 months postoperative follow-up, all retinas remained attached. The final visual acuity increased from finger counting to 0.1-0.3. CONCLUSIONS: The combination of vitreoretinal surgery and iris diaphrgm-IOL implantation is an effective method for post-traumatic aniridia, aphakia and traumatic retinal detachment. It could ameliorate photophobia and improve the biocular vision. Furthermore, artificial iris diaphragm implantation could prevent silicone oil-endothelia contact and salvage silicone keratopathy.- - - - - - - - - - ranking = 3keywords = aphakia (Clic here for more details about this article) |
4/5. Management of traumatic aniridia and aphakia with an iris reconstruction implant.We describe the clinical features and management of a 36-year-old man with aniridia and aphakia following blunt ocular trauma. Examination showed partial aniridia and aphakia. We discuss the various options available in the management of this patient and describe the surgical technique involved in the implantation of an iris reconstruction implant.- - - - - - - - - - ranking = 6keywords = aphakia (Clic here for more details about this article) |
5/5. Use of the artificial iris implant in patients with aniridia.BACKGROUND: aniridia (or partial aniridia) often occurs as a result of a penetrating ocular trauma. This condition may cause symptoms including glare, light sensitivity, reduced vision, and asymmetric appearance. Options for these patients include specialty contact lenses, corneal tattooing, and artificial iris implants. This article details six patients who experienced penetrating trauma with significant iris tissue loss and who chose to have an artificial iris implant. case reports: Six patients with traumatic aniridia were enrolled in a single-site, single-surgeon study. They were followed for one year postoperatively. All six were complex cases that had multiple eye problems, such as aphakia, corneal scarring, corneal graft rejection, and retinal detachment. All participants were male. All patients experienced decrease in glare and light sensitivity following artificial iris implant surgery. Two experienced improved best-corrected vision (BCVA). All six patients felt the cosmetic appearance of their affected eye improved. CONCLUSIONS: The artificial iris device provides an effective means of treating traumatic aniridia. Optometrists often work with patients who have experienced a penetrating ocular trauma, with complete or partial aniridia as a complication. In cases in which nonsurgical means are not effective in returning the patient to comfort and productivity, an artificial iris implant should be considered.- - - - - - - - - - ranking = 1keywords = aphakia (Clic here for more details about this article) |
