Purpose:To determine the efficacy and the safety of surgical implantation of iris diaphragm IOLs in patients with traumatic iris defects. Methods:Ten patients were evaluated in a retrospective study. Ten eyes had iris diaphragm scleral–fixated IOL implantation (Ophtec mod. 311 HMK ANI 2) for traumatic iris defects. All eyes were aphakic with no capsular remnants and had previously undergone a posterior vitrectomy for retinal detachment (5 eyes), for vitreous hemorrage (2 eyes) and for dislocated lens (3 eyes). Three eyes had also undergone a perforating keratoplasty for traumatic corneal opacities. Intraoperative and postoperative complications, visual acuity, subjective glare and photophobia and cosmetic results were evaluated. Results:Patients were followed postoperatively for a mean 17.5 months (range 6 to 40 months). Best corrected visual acuity was improved in 8 of 10 eyes, unchanged in 2 eyes. The severity of glare disability was subjectively improved in all eyes.There were no significant intraoperative complications.Postoperative complications included: transient increase of intraocular pressure in 4 eyes, persistent increase of intraocular pressure in 1 eye, mild anterior inflammation in 1 eye, corneal graft decompensation in 1 eye, and a recurrent retinal detachment with PVR in 1 eye. All IOLs remained centered and stable. All patients were satisfied with cosmetic results. Conclusions:Implantation of iris diaphragm IOL improved postoperative outcomes by correcting aphakia, by reducing glare disability in victrectomized eyes with traumatic iris defects, and by improving cosmetic results, so appearing to be a safe and effective technique.
