Closed Iridoplasty in Correction of Iris Defects of Different Etiology
Purpose
to assess the efficacy of developed methods of closed iridoplasty as a necessary step in the surgical treatment of patients with cataract complicated by iris defects.
Methods
373 patients (395 eyes) were operated. All patients were divided into two groups: first - patients with consequences of eyeball traumas (myriasis - 10.53%, iridodialysis - 8.48%, breaks of pupillary edge and coloboma - 80.99%) - 342 persons (342 eyes), second - patients with cataract combined with congenital pathology (congenital iris coloboma) - 31 persons (53 eyes). At first stage phacoemulsification was performed. At the final stage the plastic procedures on the iris were performed. The combination of different original techniques of closed iridoplasty depended on the type and extent of iris defect.
Results
Among the intraoperative complications I would like to draw attention to specific complications associated with iridoplasty: moderate hemorrhage from iris root in 2 cases, hemorrhages during the iris-scleral sutures in 10 patients and disintegration of iris in detachment site in 7 patients. In patients with congenital iris coloboma the moderate bleeding occurred during pupilloplasty, stopped with underwater coagulator.
At discharge and in long-term follow-up 98.22% of patients were satisfied with the cosmetic effect, at that it should be emphasized that patients with congenital coloboma of the iris were satisfied in 100% of cases.
Conclusion
Use of variety of closed iridoplasty techniques in complex with phacoemulsification and IOL implantation gives a chance to minimize intra- and postoperative complications, improve visual acuity, corrects cosmetic defects and to ensure the rehabilitation of patients in a short time.
