Abstract Details

Purpose:

To evaluate and compare the effects of scleral fixated rigid and foldable intraocular lenses on IOL stability, centration, safety, complications and visual outcomes

Setting:

Indira Gandhi Government General Hospital & post-graduate Institute, Puducherry, India

Methods:

This prospective study consisted of 45 patients, 3 groups(group I, group II, group III) of 15 patients each, who had trans scleral fixation of rigid polymethylmethacrylate lenses, hydrophobic acrylic and hydrophilic acrylic IOL’s respectively. All patients were followed up for 6 months. Data on visual acuity, refractive changes were evaluated pre-operatively and post-operatively. The post-operative complications were analysed in the 3 groups.

Results:

The Mean age of patients was 61.42 ± 8.15. Best Corrected Visual Acuity (BCVA) improved in all 3 IOL groups in which group I had an improvement from 0.70± 0.11 preoperatively to 0.44± 0.21 (P=0.00)at 6 months. In group II, preoperative vision from 0.62± 0.12 improved to 0.30 ±0.08(P=0.00)at 6 months.In group III, vision improved from 0.60 ±0.14 preoperatively to 0.46 ±0.20 at the end of 6 months(P=0.06).The mean Spherical Equivalent which improved from 10.16± 1.59 preoperatively to 1.96 ± 0.14 at 6 months in group I; from 10.07± 1.03 to 1.64± 0.074 at 6 months in group II and from 10.46 ± 0.92 to 1.71± 0.17 at 6 months in group III with P=0.00 in all the 3 groups.(P=0.00). The complications encountered were corneal edema, secondary glaucoma, vitreous hemorrhage, IOL decentration and tilt, suture irritation, cystoids macular edema.

Conclusions:

Trans scleral fixation of rigid and foldable lenses were safe, effective and provided encouraging visual results. Foldable SFIOLs’ remain as a good alternative to conventional rigid IOLs’, but at the cost of increased operation time. However, evaluation of the techniques in a larger population over long term is required
