Visual function after bilateral secondary implantation of the lens, which have been made 18 years after congenital cataract extraction in the patient with congenital rubella syndrome

Abstract

Comparison of a quality of vision and changes in a everyday function in 18 years old patient with congenital rubella syndrome and concomitant nystagmus who was undergoing onetime secondary implantation of intraocular lenses. A congenital cataract extraction has been done in the first years of his life. An eye defect of high hyperopia was a consequence of postoperative aphakia and has never been corrected before. A lack of cooperation from the patient was a consequence of mental retardation. Secondary lens implantations have been done to the sulcus, onetime to the both eyes. The procedure was done under total anaesthesia. An electrophysiology examinations were taken before and 24 months after the surgery. A total change in behavior and also an improvement of cognitive abilities which was accompanied by retinal response observed in electrophysiology examinations has been achieved after correction of high hyperopia by secondary lens implantation gained due to correction of both eyes. Correction of high hyperopia caused by postoperative aphakia after removal of congenital cataract resulted in improvement of vision quality, despite long-term, over ten years of absence of any correction of this defect. Obtaining this improvement effect should be an incentive to consider secondary implantation in every case, especially when the other senses (hearing) and communication organs (speech) are also disturbed, regardless of the period of non-correction.
