Modern possibilities of optical reconstructive surgery in patients after removal of the iridociliary zone tumor

Abstract

Choroid neoplasms account for two-thirds of all intraocular tumors, of which 23% are tumors of the iris and ciliary body, and the rest are choroidal tumors. After removing the tumor of the iridociliary zone (ICZ) it is necessary to perform optical reconstructive surgery to reduce light aberrations and increase visual functions.Purpose. To identify key features of the complex rehabilitation of patients after removal of the ICZ tumor.Material and methods. The clinical and functional results of the complex rehabilitation of 12 patients (12 eyes) aged from 35 to 84 years (average 66 years) were studied at least 1 year after removal of the ICZ tumor. The area of the iris defect before the reconstructive surgery ranged from 15 to 55%. Preoperative uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) were 0.26±0.19 (from 0.01 to 0.6) and 0.46±0.22 (from 0.1 to 0.8) respectively. All patients underwent phacoemulsification of cataract and implantation of the irislens diaphragm.Results. After the reconstructive surgery, UCVA and BCVA increased: 0.5±0.17 (from 0.2 to 0.7) and 0.61±0.27 (from 0.3 to 0.9) respectively. Undesirable optical effects were decreased, and patients were satisfied with the cosmetic result.Conclusion. The presented algorithm of optical reconstructive surgery after removal of the ICZ tumor creates necessary conditions for increasing postoperative functional results and improving the quality of life of these patients.
