Different techniques for artificial iris implantation with or without an intraocular lens, depending on lens status, are described in the literature. We describe a surgical technique for a custom-made artificial iris and toric-intraocular lens intrascleral flange fixation. We modified the "Backpack" artificial iris implantation surgical technique to facilitate an accurate alignment of the toric-intraocular lens in a patient with aphakia, aniridia, and high asymmetric astigmatism secondary to blunt trauma. Two months after the surgery, uncorrected visual acuity was 20/30, corrected to 20/25 with a refraction of -2.00 in the diopter sphere with no residual astigmatism. The artificial iris implant and toric-intraocular lens were well-centered. The patient was satisfied with the visual and cosmetic outcomes. This procedure, however, is not complication-free as our patient developed uveitis and increased intraocular pressure during the postoperative period, which was treated successfully.
不同的人工虹膜植入技术，包括有晶状体眼和无晶状体眼的技术，取决于晶状体的状态，在文献中有描述。我们描述了一种用于定制人工虹膜和散光型人工晶状体巩膜翼固定的手术技术。我们改进了“背包”人工虹膜植入手术技术，以方便在无晶状体眼、无虹膜和继发于钝挫伤的高度不对称散光的患者中准确对准散光型人工晶状体。手术后 2 个月，未矫正视力为 20/30，矫正视力为 20/25，屈光度为-2.00 球镜，无残余散光。人工虹膜植入物和散光型人工晶状体位置居中。患者对视觉和美容效果满意。然而，该手术并非没有并发症，我们的患者在术后期间发生了葡萄膜炎和眼内压升高，经成功治疗后得到缓解。
