Abstract Details

Purpose:

To evaluate and compare the advantages and disadvantages of iris fixation versus scleral fixation of posterior chamber foldable intraocular lenses in eyes without adequate capsular support.

Setting:

Ophthalmology department, Zagazig university hospital; the main tertiary hospital in Sharkeya governerate, Egypt

Methods:

Aphakic eyes without adequate capsular support and planned to be corrected with posterior chamber foldable intraocular lens implantation, were randomly distributed between two groups. Group A included eyes treated with scleral fixation technique and group B included eyes treated with iris suture fixation technique. Preoperative, intraoperative and postoperative data included uncorrected and best corrected visual acuity, refraction, intraocular pressure, signs of anterior segment inflammation, areas of capsular remnants, vitreous prolapse, surgical time, intraoperative difficulties, intraocular lens malposition and postoperative complications. Patients were followed up for at least six months.

Results:

Each group included 40 eyes. The mean duration of surgery was 48.3±12.6 min in group A and was 38.9±7.8 min in group B (P<0.05). Grades of anterior chamber cells and flare were higher in group B than group A (P<0.05) in 1st. week only. IOL tilt was found in 7(17.5%) eyes in group A and in 2(5%) eyes in group B (P<0.05). After 6 months, the mean BCVA was 0.82±0.28 in group A and was 0.77±0.22 in group B (P>0.05). Macular edema was found in 2(5%) eyes in group A and in 5(12.5%) eyes in group B (P<0.05).

Conclusions:

In absence of adequate capsular support, fixation of posterior chamber foldable IOL by iris suturing is associated with significantly less IOL malposition and consumes a shorter operative time than by scleral fixation. However, iris suture fixation is associated with a higher incidence of iridocyclitis in the early postoperative period.
