Pars plana vitrectomy for posteriorly dislocated intraocular lenses: risk factors and surgical approach

Retrospective study of secondary implantation of retroiridial fixation lenses in patients without capsular support: functional results and complications

INTRODUCTION

The correction of aphakia when there is no adequate capsular support remains a therapeutic challenge. The use of retroiridial fixation lenses has been extended given their lower complication rate compared to other available options.

MATERIAL AND METHODS

Retrospective study including all cases operated with an Artisan® retropupillary aphakia implant.

RESULTS

33 eyes were included out of a total of 28 patients. The follow-up period has been 38.55 months (1-96). 32.3% had a lens dislocation and 67.7% had an intraocular lens dislocation. The previous mean best corrected visual acuity (BCVA) was 1.18 ± 0.79 logMAR and post-intervention 0.36 ± 0.62 (p < 0.01). 93.8% of the patients presented a final BCVA equal to or better and 62.5% an improvement of 3 or more lines. The most frequent complication was corectopia (31.3%) and hypotony in the immediate postoperative period (21.9%). An epiretinal membrane (ERM) developed in 18.8% and cystic macular oedema (CME) in 9.4%. The presence of complications in the postoperative period did not statistically influence the final BCVA.

CONCLUSIONS

The retropupillary Artisan® lens allows the correction of aphakia with satisfactory visual results and a low rate of complications.
