Advantages:

To show the long-term results and to demonstrate that retropupillary iris-claw lens implantation is a safe and effective method for the correction of aphakia in patients without capsule support. This surgical procedure has the advantages of a posterior chamber implantation with a low intraoperative and postoperative risk profile.

Methods:

This retrospective study included 19 eyes of 16 patients who underwent vitrectomy followed by Artisan aphakic intraocular lens implantation between February 2008 and November 2013 at the University Central Hospital of Asturias, Oviedo, Spain due to lens luxation (10 eyes) or IOL-bag complex luxation (9 eyes). Preoperative data collected included demographics, etiology of aphakia, and best corrected visual acuity. Postoperative outcomes included the best corrected visual acuity, and development of complications.

Effectiveness / Safety:

Sixteen patients (9 males and 7 females) were included. Mean age was 62.31 years old (range: 20-75). The etiology of aphakia was complex IOL-bag luxation in 10 eyes, and lens luxation in 9 eyes. IOL-bag complex luxation was secondary to: trauma associated to pseudoexfoliation syndrome (one case), previous vitrectomy due to retinal detachment (5 cases), and CMV retinitis (4 cases). Lens luxation was secondary to: trauma (3 cases), CMV retinitis (one case), and Marfan syndrome (5 cases). In all cases, vitrectomy was followed by Artisan lens retropupillary implantation for surgical correction of aphakia. During the surgery no complications were observed. All of our patients had a well-centered IOL postoperatively and during the follow-up. The mean follow-up period was 19.8 months (range: 3 – 72 months) for patients with LIO luxation, and 33.88 months (range: 3-54 months) for patients with lens luxation. Preoperative Best Corrected Visual Acuity (BCVA) was 0.06 in IOL-bag complex luxation group, and 0.26 in lens luxation group (in decimal notation in both cases). Postoperative BCVA was 0.49 in IOL-bag complex luxation group, and 0.82 in lens luxation group.

In conclusion, retropupillary iris-claw lens implantation can be a safe and effective method for the correction of aphakia in patients without capsule support, after lens luxation or IOL-bag complex luxation. Artisan implantation is a safe and effective method for these cases, above all for those patients with age inferior to 70 years old. In older patients, anterior chamber intraocular lens implantation should be the choice procedure.
