Treatment of IOL-capsular complex dislocation

Objective To evaluate the efficacy of IOL exchange with iris-claw IOL(Artisan) for intraocular IOL-capsule complex dislocation. Methods Retrospective case series.The data of 8 eyes of 8 cases of IOL-capsule dislocation accepted IOL exchange with Artisan IOL from Apr. 2015 to Jan. 2018 in this hospital were analyzed. Results The followed-up time was 6-18 months.Postoperative UCVA (LogMAR) was significantly ameliorated from 1.09±0.56 to 0.34±0.11(t=3.989, P=0.005). Postoperative BCVA(LogMAR) was also significantly ameliorated from 0.29±0.12 to 0.18±0.10(t=3.913, P=0.007). There was no significant difference in intraocular pressure(t=1.706, P=0.132)between before and after surgery[(12.60±1.87)mmHg v. s.(10.31±4.67)mmHg(1 mmHg=0.133 kPa)]. Mean postoperative endothelial cell density(ECD) was (2 161.25±358.95)/mm2, preoperative ECD was (2 411.13±404.44)/mm2, and the difference was statistically significant(t=4.686, P=0.002). There was no significant difference in central macular thickness (CMT)(t=-1.974, P=0.089) between before and after surgery [(197.63±32.04)μm v. s.(205.13±30.44)μm]. Conclusion Artisan IOL for the treatment of IOL-capsule complex dislocation is an effective and safe surgical procedure. Key words: Dislocation, complex IOL; IOL, iris-claw, Artisan; Exchange
