Methods: This was a retrospective non -comparative study of six eyes in five patients with iris defects. The causes o f such defects included congenital aniridia, traumatic aniridia, and oculocutane ous albinism. Three eyes underwent primary implantations of a black diaphragm IO L, and three eyes were given secondary implantations. The visual acuity, subject ive severity of glare, postoperative anatomical outcome and any intraoperative o r postoperative complications were reviewed. Results: The mean follow-up period was 20.6 months (range 3-29 months. All patients showed stable or improvement in best-corrected visual acuity postoperatively. Glare and photophobia had impr oved subjectively in all patients after implantation of the black diaphragm IOL. Intraoperative complication included one case of hyphaema and iris damage durin g insertion of the IOL. Postoperative complications included intraocular inflamm ation with choroidal detachment, secondary glaucoma, and persistent epithelial d efect after surgery. None of the patients developed decentration of IOL after su rgery. Conclusion: The black diaphragm aniridia IOL is useful in the management of the condition in patients with iris deficiency including oculocutaneous albin ism. Intraoperative and postoperative complications are not uncommon, and patients should be monitored carefully in the perioperative period.展开更多
