Abstract Details


To evaluate the visual outcomes of patients who underwent cataract surgery in a single center prospective study with implantation of a transitional toric monofocal intraocular lens (Precizon Toric IOL, Opthec, The Netherlands) in combination with the Cassini topographer and the RoboMarker.


nordBlick Augenklinik Bellevue, Kiel, Germany


In our prospective study 30 eyes of 15 patients were included till now. Mean age was 67 years. The follow up was at one day, one week, four weeks and three month postoperatively. Inclusion criteria were cataract eyes with a regular astigmatism over 0.75dpt and no other pathologies. Corneal astigmatism was measured by the Cassini topographer (Cassini, The Netherlands). The axis marking was performed by the RoboMarker. (Surgilum,USA). UCDVA, CDVA, spherical equivalent and rotation stability was recorded. Intraoperative and postoperative adverse events were documented.


Mean corrected corneal astigmatism was 1,72dpt (range 0.75-3.0dpt). At three months follow up mean UCDVA was 0.05 1 logMAR and mean CDVA 0.000.10 logMAR. All patients were specatcle free for far distance. No intraoperative or postoperatve adverse event were seen. Only one patient complained about severe postoperative dry eye which was not related to the type of IOL implanted. The toric iol was in average 3 degrees within the intended implantation axis. No secondary rotation of a iol was necessary due to rotation instability.


The Precizon toric is a safe and effective toric IOL in patients with cataract and astigmatism in combination with the Cassini topographer for measurement of the total corneal astigmatism and the RoboMarker for axis marking. It provides a high level of independence of glasses for far distance and provides a high rotation stability.
