We have no financial interest Purpose: To study results of 5 cases of PK & 1 case of descemet’s stripping femtosecond laser assisted endothelial keratoplasty with retrofixation of Iris claw lens with min. F/U of 6 mths.
Methods In cases without posterior capsule where keratoplasty is required retrofixated Iris claw lens after +/- ACIOL explantation & anterior vitrectomy done in cases of bullous keratopathy Routine post op F/U up & treatment done.
Methods Iris enclavation areas monitered by UBM at 3 & 6 mths. IOL and Iris planes compared on UBM AC & vitreous cells monitered postop at 1,2,4,12 & 24wks . Pre and post op BCVA at 6 mths compared.
Results Iris enclavation was firm in all cases till last follow up in all 6 cases. Iris & IOL planes were parallel in all 6 cases without any tilt. No cases had postop uveitis.
Results 1 case had acute allograft rejection at 8 wks 1 had graft infiltrate (GPC in pairs) which led to graft failure at 11 wks Still till last F/U, retrofixated IOL was well in place. In rest of the cases, BCVA improved from average 1.4/60, <N36 to 6/24, N 8.6 at 6 mths.
Conclusion Retrofixation of Iris claw lens appears to be good alternative to SFIOL or aphakic CLs in cases without posterior capsule where keratoplasty is needed Further long term studies comparing results with SFIOL cases are of course required to know the efficacy & safety of these lenses.
Conclusion Iris atrophy leading to late slippage of the lens on long term seems unlikely but needs to be monitered and studied. Can be used with even dilated, fixed irregular pupils provided we get a good chunk of iris for enclavation on both sides.
