Femtosecond lasers allow the precise placement of arcuate keratotomy incisions in patients undergoing cataract surgery. Though these surgical devices have been available for several years, most current nomograms designed to reduce astigmatism with these incisions are derived from those developed for metal or diamond knives. Anecdotal reports from surgeons indicate that the previous nomograms have limited accuracy in the setting of femtosecond laser surgery.~LaserArcs.com is an online arcuate incision nomogram calculator initially developed on the basis of 12 months of data tabulation of patients undergoing femtosecond surgery with arcuate incisions. since that time, its user base has grown because of the high accuracy its model provides. Currently over 3500 calculations are performed each month on this platform.
