Strabismus Calculator will save you the hassle of always checking or double-checking recession/resection values prior to operating on a surgical patient with strabismus. It simply contains all the data from well known published nomograms and makes them available to you wherever you are and whenever you want. You just have to input the amount and type of eye deviation, and it will provide you with all possible combinations of surgery along with the corresponding recession/resection values. Later upgrades and newer versions of Strabismus Calculator will be available for free once you buy the software.
