Abstract:
We report a new procedure for intra-operative toric intra-ocular lens (IOL) axis assessment in order to achieve optimal implantation. IOL implantation procedure was directly recorded. An assessor estimated the angle formed by the marked 0-180 axis and the toric IOL axis after implantation with the use of the appropriate software. If IOL implantation was assessed to be inaccurate, the surgeon was advised to correct IOL positioning by rotating the IOL clockwise. The assessment procedure was repeated until accurate IOL positioning was achieved.
