Long-term efficacy and complications of black diaphragm intraocular lens implantation in patients with traumatic aniridia.

[aniridia]

To determine the efficacy and complications of long -term black diaphragm intraocular (BDI ) lens implantation in patients with traumatic aniridia .This study analysed the demographics , clinical evaluations and treatments of 95 patients with BDI lens implantation and 75 patients who wore rigid gas-permeable (RGP ) contact lenses (CLs ). The clinical examinations included evaluations of visual acuity (VA ), best-corrected visual acuity (BCVA ), intraocular pressure measurements (IOP ), and corneal endothelial cell density (ECD ). Ultrasound biomicroscopy (UBM ) was used to observe the haptic lens positions .In the BDI group , light sensitivity dramatically decreased postoperatively in all patients , and 78 patients (82 .1 %) had a BCVA score >20 /200 . A total of 36 eyes (37 .89 %) developed elevated IOP after the BDI lens implantation , and 12 eyes (12 .63 %) underwent glaucoma laser surgery . Corneal decompensation occurred in nine eyes (9 .47 %), three of which developed glaucoma . Twelve patients (12 .63 %) experienced limbal stem cell failure , and 16 patients (16 .84 %) had eccentric BDI lenses . All patients in the RGP group had a BCVA score â‰¥20 /200 . Only seven eyes (9 .3 %) had cornea complications . There were no statistically significant differences in either the IOP or ECD after wearing the RGP CLs .G laucoma , corneal decompensation , limbal stem cell failure , and eccentric BDI lenses appeared to be the major long -term complications in BDI lens implantation . BDI lens implantation could effectively improve postoperative outcomes by reducing glare disability , improving visual performance , and addressing cosmetic issues . Because the implantation of the BDI lens in traumatic aniridia had a high incidence of complications , this treatment should be used with caution , and the long -term complications should be seriously considered .
