Effectiveness of surgical treatment for spontaneous «intraocular lens – capsular bag» complex dislocation, developed after phacoemulsification

Abstract

Purpose. To evaluate method for spontaneous dislocation of «intraocular lens – capsular bag» complex (CICB) surgical treatment, that developed after phacoemulsification (PE), in relation to its severity. Material and methods. Clinical material included 36 patients (36 eyes) aged 61 to 89 years. Spontaneous dislocation of CICB after PE performed varied from 3 months to 11 years after surgery, average 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 treatment was not performed in patients with the 1st degree of CICB dislocation. At the 2nd degree of CICB dislocation and more severe, patients underwent its surgical correction, according to severity of the eye condition. Results. All surgical intervensions were carried out as planned, without complications. The postoperative response of the eyes was evaluated on the 1st and next days of the postoperative period (SN Fedorov, EV Egorova, 1992). In all cases, it corresponded to the amount 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 6 eyes (21%) – did not change significantly; in 8 eyes (29%) we reached the indexes that took place immediately after PE. Conclusion. Thus, in our experience, the surgical correction of spontaneous dislocations of CICB of the 2–4 degrees have shown itself to be effective in all of these cases. Key words: phacoemulsification, spontaneous dislocation of the «intraocular lens – capsule bag» complex, surgical treatment.
