Abstract Details


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


Indira Gandhi Government General Hospital & Post-Graduate Institute, Puducherry, India


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.


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.


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.
