| description | Purpose. To analyze the frequency, terms and risk factors of late IOL dislocation.Material and methods. A retrospective cohort study was conducted based on archival data of 70 787 cases of the senile cataracts phacoemulsifications performed in 2002–2019 years. Statistical processing of the results and Kaplan–Meier analysis were performed using the SPSS 11.0 program (STATA).Results. 320 patients in the study group were treated for late IOL dislocation at various postoperative periods. The average age of the patients was 76.2±12.5 years at the moment of reconstruction procedure. The periods from the moment of IOL implantation to its dislocation varied from 4 months to 17.58 years, the average term was 6.95±3.67 years. IOL reposition was performed in 272 cases (85.0%) and IOL change – in 48 cases (15.0%). The leading risk factor was pseudoexfoliation syndrome detected in 239 patients (74.7%). Among other factors there was high myopia (72 patients; 22.5%), in 78 cases there were the surgery procedures between cataract surgery and IOL dislocation: glaucoma surgeries – 27 cases (8.4%), vitreal surgeries – 9 cases (2.8%), laser discission of secondary cataract – 42 cases (13.1%). The cumulative 5-, 10-, 15-, and 18- year risk of late IOL dislocation was estimated using Kaplan–Meier analysis.Conclusion. The dynamics of the number of reconstructive operations at late IOL dislocations has a tendency to increase. The average term from the IOL implantation to its dislocation was 6,95±3,67 years. The leading risk factor was pseudoexfoliation syndrome. The cumulative 5-, 10-, 15-, and 18-year risk of late IOL dislocation was 0.2; 0.7; 1.15; and 1.4%, respectively. |
