Возможности хирургической коррекции спонтанной дислокации комплекса «интраокулярная линза – капсульный мешок», развившейся в различные сроки после факоэмульсификации возрастной катаракты

Abstract

Purpose. Substantiation of surgical correction method of spontaneous dislocation of the complex «intraocular lens – capsular bag» (CICB), that developed after phacoemulsification (PE), in relation to its severity. Material and methods. The clinical material consisted of 28 patients (28 eyes) aged 61 to 89 years. The terms of spontaneous dislocation of CICB after PE performed widely varied from 3 months to 11 years, averaging 5 ± 2 years. According to our proposed classification degrees of severity spontaneous dislocation of CICB, its 1st degree took place in 8 eyes; 2nd – in 9 eyes; 3rd – in 16 eyes; 4th – in 3 eyes. Surgical correction was performed in all cases dislocation of CICB 2nd or more degrees, the volume of which was commensurate with the initial severity of the eye condition. Results. All operations were carried out as planned, without complications. The postoperative response of the eyes was assessed on the 1st and next days of the postoperative period. In all cases, it corresponded to the volume of performed surgical intervention. So, in 19 eyes, it corresponded to the 1st degree; in 6 eyes – 2nd degree; 3 eyes developed 3rd degree postoperative response of the eyes (postoperative uveitis). Indexes of uncorrected visual acuity on days 3–5 in 14 eyes (50 %) ranged from 0.05 to 0.4; in 8 eyes (29 %) we achieved indexes like they were immediately after PE. Conclusion. Thus, in our experience, the surgical correction of spontaneous dislocations of CICB of the 2–4th degrees has shown itself to be effective in all of these cases.
