| Popis: | Purpose . To study frequency of spontaneous dislocation of intraocular lens – capsular bag complex in various periods after phacoemulsification (PE) of age-related cataracts, develop its clinical classification based on objective criteria for gradation of degrees of severity. Material and methods . All cases of intraocular lens – capsular bag complex dislocation occurred in our clinic in different periods after PE of age-related cataract in 2010–2018 were selected. 24231 PE of agerelated cataract were performed in our clinic during this period. The proportion of spontaneous dislocations of intraocular lens – capsular bag complex having non-traumatic origin was at least 0.26%. We carried out retrospective analysis of the possible causes of spontaneous dislocation of intraocular lens – capsular bag complex in these patients. Results . All 63 patients with dislocation of intraocular lens – capsular bag complex presented themselves to the clinic. There were 39 men and 24 women. Their age ranged from 50 to 89. The time of formation of intraocular lens – capsular bag complex dislocations was conditionally estimated according to the data presented by the patients. It varied widely from 3 months to 14 years, averaging 5.45±3.6 years. In the course of time after performing PE, the frequency of dislocation progressively increased. Conclusion . The criteria for the presence and severity of spontaneous dislocation of intraocular lens – capsular bag complex was: 1) severity of dislocation of intraocular lens – capsular bag complex from its correct anatomical position, based on biomicroscopy, 2) uncorrected visual acuity, 3) intraocular pressure, 4) risk of intraocular complications. Our in-depth clinical analysis of the severity of postoperative dislocation of intraocular lens – capsular bag complex allowed us to create simple and affordable clinical classification of this condition. |
