Abstract Details
Purpose:
To evaluate the effectiveness of various methods of surgical correction of late spontaneous dislocation of the 'posterior chamber IOL - capsular bag' complex.
Setting:
S. Fyodorov Eye Microsurgery Federal State Institution
Methods:
An analysis of 223 case histories of patients with late dislocation of posterior chamber IOLs, operated during 2013-2015 was carried out.
Results:
Average time before IOL luxation was 8.78 ± 4.85 years. 84% patients had II-III degree, and 16% patients - IV degree of IOL luxation (Hayashi K.). 85.20% of patients had pseudoexfoliation syndrome, 74.60% had myopia, 59.20% had glaucoma.
In 60.5% of cases, replacement of dislocated IOL by pupil fixation IOL was performed. Repositioning and suturing of IOL were performed in 39.5% of cases. Best-corrected visual acuity in 6-12 months after IOL replacement was 0.39±0.25 (p<0.001), and after IOL repositioning was 0.49±0.22 (p<0.001). After IOL replacement, there was a significant increase in postoperative astigmatism from -0.4±0.8 to -1.94±1.61D (p<0.001).
Conclusions:
The approach to surgical treatment in late spontaneous IOL dislocation in the capsular bag is primarily determined by IOL luxation degree, the type of dislocated IOL, and the surgeon's preferences. Insufficient visual functions after surgical treatment are caused by the presence of glaucoma, age-related macular degeneration, as well as by the intensification of postoperative astigmatism.
