The clinical efficacy of secondary implantation of iris-fixated intraocular lens for traumatic aphakia

Objective To evaluate the clinical efficacy of secondary implantation of iris-fixated intraocular lens for traumatic aphakia. Methods Postoperative outcomes of secondary implantation of iris-supported Artisan IOL in 18 unilateral aphakic patients with penetrating eye injuries or contusion were analysed retrospectively. The uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), spherical equivalents (SE), and endothelial cell density (ECD) were compared before and after the surgery. Results Mean postoperative follow-up time was (11.42±4.51) months. The UCVA was improved in all patients. The mean endothelial cell loss rate was 3.7% in the first 3 postoperative months. 18 eyes achieved the desired anatomic results. No intraoperative complication occurred. Transient high intraocular pressure occurred in 3 cases, 2 cases with iris depigmentation. And no retinal or choroidal detachment, macular edema, hyphema or vitreous haemorrhage was observed. Conclusion Secondary implantation of iris-fixated IOL is an effective and safe procedure for traumatic aphakia, which has good visual rehabilitation and low occurrence of complication.
