Abstract Details

Purpose:

to evaluate the longtermRotational Stability with regards to the axis of placement and and Predictability Of Foldable Toric Iol In Correction Of Astigmatism In Cataract Surgery Patients

Setting:

Narayana Nethralaya superspeciality Eye Hospital , Narayana Hrudalaya Health city , Bommasandra . Bangalore, India

Methods:

Patients meeting inclusion and exclusion criteria for toric IOL implantation were included in the study. Manifest refraction and best corrected visual acuity at 6 weeks post op was performed. IOL orientation was verified on the slit lamp on post-op day 1 and at 6 weeks.Toric iol calculator determined the site of incision and orientation of iol axis. Acrysof toric iol was implanted in all cases.

Results:

40 Eyes of 25 patients were evaluated. Mean age of the patients was 58.8 and the male to female ratio was 1.1:1. At final follow up of 6 weeks post op, uncorrected distance visual acuity of 6/9 or better was 92.5%(37 of 40 eyes) . Corrected distance visual acuity was 6/6 in all cases . The mean rotation of toric iol axis was 2.56 degrees and perfect axis alinghment was found in 33.3% (12 eyes). 40% of the 90 +/- 30 degrees axis alignment had perfect axis alignment compared to 32.3% with 180 +/- 30 degrees axis.

Conclusions:

Early and longterm (6 weeks) post operative follow up show Alcon AcrySof Toric IOL has good rotational stability and is predictable and effective in correction of pre-existing corneal astigmatism in patients undergoing cataract surgery. Manual keratometry values give predictable results in toric iol calculation. Iol’s placed in the 90 +/- 30 degress axis were found more stable than the 180 +/- 30 degrees axis.
