Abstract

Purpose: To compare a new slit lamp based toric marker for corneal marking with conventional techniques of corneal marking

Methods: We have designed a new Slit lamp based Toric Marker to assist a handsfree access to the surgeon for accurate toric marking preoperatively.

30 consecutive eyes were marked using this new marker and 30 consecutive eyes were marked using conventional marker.

The results were evaluated photographically using a digital planimetry software on pre and post-operative photographs.

Postoperative residual astigmatism were compared using these 2 markers and were studied statistically.

Results: Software based analysis showed significantly more accurate placement of the corneal marks as well as IOL placement. Post-operative outcome at 6 months showed significantly better correlation with anticipated residual astigmatism in the group with our marker. Conclusions: STORM was found to be more accurate and reproducible than currently used techniques.
