Abstract Details


To evaluate an intra-operative marking technique using the body axis as a reference to allow intra-operative toric intraocular lens (IOL) alignment without pre-operative corneal marking


Vienna Institute for Research in Ocular Surgery (VIROS)


Consecutive patients who were scheduled for cataract surgery, but a non toric version of an IOL, were included in this study. In all cases cataract surgery was performed as standard. Additionally, the horizontal meridian of the cornea was aligned using the body axis as a reference axis with the patient on the operating table. Afterwards, blue ink was used to mark the horizontal meridian. Post-operative marking alignment was assessed from standardised retroillumination photographs taken immediately after surgery.


In total, 40 eyes of 40 patients were included. No adverse events were reported and feasibility of the intra-operative marking was high. Mean absolute deviation between the post-operative and the aimed 180° horizontal meridian was 4.1° (SD:2.47°). Mean absolute deviation between the marked caruncula line and the intra-operative marking was 5.1° (SD: 4.15).


Intra-operative marking using the body axis as a reference was relatively reliable. Although modern marking techniques are slightly more accurate, this could be a good option for non marked patients in the intra-operative setting, or difficult cases.
