Клинико-функциональные результаты имплантации иридохрусталиковой диафрагмы с одномоментной сквозной субтотальной кератопластикой: опыт 15-летнего наблюдения пациента
Abstract
Combined traumatic injuries of the anterior eye segment are attributed to the severe consequences of the injured organ of vision. Iris\xa0defects result in spherical and chromatic aberrations, diplopia, flares, severe photophobia, cosmetic defects, and significantly reduced\xa0visual acuity after the injury. The literature describes various methods to restore visual functions impaired as a result of aniridia. Use\xa0of an artificial iris together with an intraocular lens pathology results in optimal reconstruction and recovery of normal anterior segment\xa0anatomy and topography. In this paper, we provide a report on a patient followed up for 15 years after combined reconstruction\xa0eye surgery for an off-the-job penetrating eye injury sustained in 2003. A complex intervention was required due to the involvement of\xa0the cornea, iris, and lens. In 2004, the patient underwent a lens-iris diaphragm implantation combined with penetrating keratoplasty.\xa0The diaphragm implantation was followed by an improvement in visual acuity and elimination of photophobia and flares. There were no\xa0intra- or postoperative complications. Two years later, LASIK refractive surgery was performed on the corneal transplant to eliminate\xa0induced ametropia. The patient retained good eye function, with a stable position of the lens-iris diaphragm, for many years after the\xa0diaphragm implantation, keratoplasty, and refractive surgery. In 2018, he had an intravitreal implant impregnated with dexamethasone,\xa0as changes in the retina had developed. The long-term follow-up in this case demonstrates that the implantation of a lens-iris\xa0diaphragm resulted in an elimination of undesirable optical events associated with aniridia and produced an optimal functional result,\xa0while also improving the patient’s quality of life with a good aesthetic effect.
