This document discusses a study evaluating the use of consistent preoperative marking and transitional conic cylinder intraocular lenses (IOLs) to improve results of astigmatism correction during cataract surgery. 79 eyes underwent cataract surgery with implantation of transitional conic surface IOLs. A preoperative topographic limbus marking was performed for reference during surgery. Early results suggest a more effective preoperative marking technique and use of conical transition IOLs can achieve good astigmatism correction and precise IOL power calculation. Further evaluation of intraoperative digital alignment and reduction of aberrations may improve refractive outcomes.
