Abstract Details

Purpose:

To evaluate and compare the effects of scleral fixated rigid and foldable hydrophilic and hydrophobic 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( PMMA) lenses, hydrophobic acrylic and hydrophilic acrylic IOLs�â�€�™ respectively. All patients were followed up for 6 months. Data on best corrected visual acuity(BCVA) , refractive changes were evaluated pre-operatively and post-operatively. The post-operative complications were analysed in the 3 groups.

Results:

Mean age of patients was 61.42�Â�±8.15. BCVA improved in all 3 groups.Group I had an improvement from 0.70�Â�± 0.11 to 0.44�Â�± 0.21 (P=0.00), group II from 0.62�Â�± 0.12 to 0.30 �Â�±0.08(P=0.00) & group III from 0.60 �Â�±0.14 to 0.46 �Â�±0.20 at 6 months(P=0.06).Mean Spherical Equivalent improved from 10.16�Â�± 1.59 to 1.96 �Â�± 0.14 in group I; from 10.07�Â�± 1.03 to 1.64�Â�± 0.074 in group II & from 10.46 �Â�± 0.92 to 1.71�Â�± 0.17 in group III with P=0.00 in 3 groups at 6 months.The complications encountered were corneal edema, secondary glaucoma, vitreous hemorrhage, IOL decentration, suture irritation, cystoid macular edema.

Conclusions:

Trans scleral fixation of rigid and foldable lenses were safe, effective and provided encouraging visual results. Foldable SFIOLs�â�€�™ remain as a good alternative to conventional rigid IOLs�â�€�™,but at the cost of increased operation time and technically more demanding with surgeon factor playing an important role for injector implantation of foldable IOL�â�€�™s for IOL stability and centration.
