Traumatic Iris Deficiency Such As Eye Implant Lie Between The Long-term Follow-up Of Intraocular Lens And Iris Embedded Technology Improvement

Purpose:Traumatic rupture of the globe is often associated with serious iris, lens and vitreoretinal damage. The visual function can be recovered partly in most patients. However, spherical aberration and chromatic aberration caused by defects in the iris can lead to severe photophobia and glare in such patients. By far, many favorable results of black diaphragm intraocular (BDI) lens implantation in eyes with aniridia and aphakia have been reported. And most scholars believe that the implantation of the BDI lens is an effective way to treatment eyes with aniridia and aphakiaWe followed up the patients who implanted BDI lens at Qingdao Eye Hospital and found that secondary glaucoma and corneal endothelial decompensation occurred in some patients during the long-term follow-up. Aiming at this problem, we improved the implant technology in order to avoid the long-term complications after the implantation of BDI lens. We followed up the patients with the use of improved technology, and report the result of long-term results.Method:BDI lens was used in Qingdao Eye Hospital since September1998, and a total of78eyes of78patients implanted BDI lens by December2012. At the first phase from September1998to August2007, we implanted BDI lens for53patients. At the second phase from November2008to December2012, we improved implantation techniques and implanted BDI lens in25patients. We contacted the patients with a variety of ways such as by telephone, Internet and home visits, and invited them back to the hospital for examination, focusing on corrected visual acuity, intraocular pressure, corneal endothelial count, and BDI lens position with UBM.Result:We found30patients of the first phase, and18cases of which have maintained a good eye condition. Corneal endothelial decompensation and secondary glaucoma occurred in12patients.25patients in the second phase who received modified technique of BDI lens implantation maintained good eye condition, without serious complications occurred.Conclusion:BDI lens should be chosen suspension implantation, rather than the ciliary sulcus or capsular bag implantation. The implant position need be appropriate backward and the haptics must be fixed firmly. BDI lens cannot contact with corneal endothelium and angle of anterior chamber, in order to avoid long-term complications of the surgery.
