In the last update of RSG you can see the corneal SIA of each eye. You could see the centroid values pre-op and post-op but now you can also see the individual SIA of each eye, the centroid value of the SIA and the axis of the standard deviation of x and y. In this new graphics you can click on a single eye to see more information or click and drag around some point to get the table of those points.

The following graphics shows the same eyes with both types of graphics available in RSG.



You can test RSG here.


In the last update for RSG I have included the SIA consistency. Up to now you could get your SIA but there was no measure about its consistency, you got an ellipse with the standard deviation (sd) of x and y in the graphic but it was not quantified and when subdividing per factor not even the ellipse. Now you got to the left the mean SIA for the cornea and the SIA sd, if you choose to separate the graphics by factor you get within each graphic the number of eyes, mean and sd of the SIA for each factor. That SIA sd represents the radius in diopters of the circle with the same area as the ellipse in diopters which is easier for interpretation.

The update is online and you can try it here.



Before analyzing refractive surgery outcomes with RSG you need to get data in it. With this cheatsheet you can see how to make the excel file and what is the first thing you see when you upload it.

You can contact us if you want your exported data to be automatically imported in RSG.



The new update for RSG is online. Now when the program is busy making calculations you will see an indicator:




Also a progress bar will be shown when you want to download a report:



The RSG cheat sheet lets you find your way around the program. Where to find a graphic, what are the options for the graphic and other notes like graphics manipulation.
