Abstract

Objective: to evaluate the clinical and functional results of the implantation of sectional modification of iris-lens diaphragm in patients with severe post-traumatic pathology of the anterior segment of the eye. Materials and methods. 7 patients (7 eyes) with post- traumatic aniridia, aphakia who were presented for reconstructive surgery were under observation. During the operation the artificial iris (The H1 model, «Reper-NN», Nizhny Novgorod) and an optical element have been consistently implanted to all patients. Due to the lack of safe structures of a capsular bag, the artificial iris was fixed by 3 scleral sutures. Standard and special ophthalmological examinations of patients were made before surgery and 3 months later. Results of the study. After the surgery the uncorrected visual acuity and the best-corrected visual acuity were increased compared with preoperative values. IOP remained stable in all patients, with the implant centered throughout the follow-up period. There were no intraoperative complications. Among the postoperative features, it was worth noting the transient edema of the cornea tissue, which was resolved by the 3-7 day of inpatient treatment. Patients noted a significant decrease of photophobia, undesirable visual effects (glare, halo) and were satisfied with the postoperative cosmetic result. Conclusion. Based on the presented clinical research, the possibility of using the sectional modification of iris-lens diaphragm in optical-reconstructive surgery of the anterior segment of the eye was shown. The prospects of development are the potential to replace the optical element, which is especially important in pediatric ophthalmic traumatology, including the need for spherotorical correction. In the case of preservation of the structures of the capsular bag in patients, it is possible to implant sectional modification of iris-lens diaphragm through surgical access to 2.4 mm, which minimizes the value of induced astigmatism (2 figs, bibliography: 11 refs).
