Abstract Details

Purpose:

To compare and evaluate the visual outcome and complication rate of two different techniques of surgical management of intraocular lens (IOL) dislocation or aphakia correction. In addition, to evaluate possible risk factors for IOL dislocation and to determine the time interval between primary cataract surgery and the secondary IOL procedure.

Setting:

Department of Ophthalmology, The NU Hospital Group, Uddevalla, Sweden,

Methods:

Medical records were reviewed for all patients who had surgery for IOL dislocation or aphakia. The two most common procedures; scleral suturing of dislocated in-the-bag IOL (group1; n=35) and retropupillary fixation of iris-claw IOL (group2, n=75) were analyzed for differences in complications and visual outcome. Main outcome measures were best-corrected visual acuity (BCVA), reoperations, and complications.

Results:

109 eyes (65.5% females) were included. Mean age was 79.0 (SD 8.8) years and pseudoexfoliations were present in 67.4%. Mean interval between cataract surgery and second management was 93 months (SD 89.9, range 0.5-648 months). The intraocular pressure (IOP) decreased postoperatively in both groups (mean decrease -3.7 mmHg for scleral sutured IOLs and -2.1 mmHg for iris-claw) but no significant difference was seen between groups (p=0.264, t-test). Both groups showed significant improvement in BCVA with no significant difference between groups (p=0.056). No intraoperative complications occurred whereas one choroidal and one retinal detachment occurred postoperatively in the iris-claw group.

Conclusions:

Both methods are safe and effective with few complications. The majority of patients had pseudoexfoliations and IOP decreased postoperatively in both groups. Both group show significant improvement in visual acuity.
