Abstract Details

Purpose:

To compare visual outcomes observed postoperatively in patients with subluxated intraocular lens (IOL) treated with iris fixation and scleral fixation of IOL

Setting:

Department of Ophthalmology, Haeundae Paik Hospital, Inje University College of Medicine, Busan, South Korea

Methods:

In this retrospective single-surgeon interventional case series, 75 consecutive patients who had referred with IOL subluxation from 2010 to 2013 were enrolled and divided into two groups by the surgical method performed to correct subluxation. Thirty-five patients with subluxated IOL were treated with iris fixation of IOL using Modified McCannel method (IF group) and 40 patients underwent scleral fixation of IOL (SF group). The main outcome was postoperative corrected distant visual acuity (CDVA), surgically induced corneal astigmatism, operation time, and complication including recurrence of IOL subluxation.

Results:

Subluxation of IOL was corrected successfully during the first operation in all patients in the both groups. Postoperative CDVA, converted into LogMAR, improved significantly from 0.55 preoperatively to 0.22 in IF group, and from 0.52 to 0.24 in SF group (p<0.001, p=0.001, respectively; Wilcoxon Signed Rank test). Corneal astigmatism was not induced significantly in the both groups (-0.03 Diopter(D) in IF group and 0.02 D in SF group, p>0.05 in both groups; Mann-Whitney U test). Mean operation time was significantly shorter in IF group as 38.9 min compared to 49.3 min of SF group (p=0.002, Mann-Whitney U test). Recurrence of IOL subluxation occurred 5 eyes (14.3%) in IF group and 3 eyes (7.5%) in SF group, however the between-group difference was insignificant (p>0.05, Fischer’s exact test).

Conclusions:

Iris fixation of IOL seems to be a good option for the treatment of IOL subluxation, considering less operation time but comparable clinical outcome to the scleral fixation method.
