Summary The effectiveness of the correction of astigmatism majorly depends on the accuracy of the positioning of the toric lens implant in the eye. Appropriate removal of viscoelastic, proper centration and axis alignment have a direct impact on the effectiveness of the astigmatic correction. For phakic toric lenses positioned in the anterior or posterior chamber of the eye or adapted to the iris, as well as for pseudophakic toric lenses postioned in the capsular bag, the intraoperative use of real time OCT scanner (e.g. RESCAN 700 Zeiss) allows for an evaluation of the lens positioning. iOCT plays also a role in the estimation of the axial position of the lens, e.g. for customization of the IOL constants for formula‐based IOL calculation or the circular contact force to the posterior capsule for prevention of secondary cataract formation. In this talk we would like to show the potential of iOCT use and tailor out the add‐on value of this exciting technology.
