The last update for RSG is online. In the Standard graphs -> Astigmatism tab, you can now get the mean correction index, and the mean index of success for the astigmatism corrections. The correction index indicates if we over or undercorrect in magnitude but doesn't tell if we are treating the right direction, the angle of error indicates if we treat at the right direction, the index of success is a relative measure of success related to the amount of targeted astigmatism and ideally would be 0.
The success of the astigmatism surgery in percentage indicates how well we are doing taking into account the magnitude and the axis:
100% success will mean that all astigmatisms are on target in magnitude and axis, if we want no astigmatism postop then all the eyes will have no astigmatism post-op
0% success will mean, in the case we want no astigmatism postop, that the residual astigmatism is equal or larger in magnitude than the initial astigmatism.

In the astigmatism tab when you choose the preop cilinder range you can see how many eyes are shown. Also I added a new widget that tells you the mean surgical induced astigmatism for all the eyes (not just the selected).
Now, if in the excel you upload, you put as cilinder and axis preop and postop the K difference with the axis of the flattest meridian (the corneal astigmatism with negative cilinder) instead of the refractive, you can see the corneal astigmatism you are inducing.
I want to thank Cesar Albarran for verifying this with me.
Also a minor bug that made some graphics not to be shown when in the excel all the cilinder preop values where the same has been solved.
In the last update of RSG online I have change the Histograms tab for the Distributions tab where a submenu will let you see histograms and bar graphs or boxplots. In the boxplots tab you can find, indeed, boxplots! They show the SE postop by age category, each of the two custom factors and the combination of the two custom factors, which you can switch with a checkbox. With this graphics you can compare results easier.
Also on the Upload data tab, under the data table you can find two tables showing the amount of missing values for the variables that are allowed to have them and the number of unique values for the two custom factors columns. This might give you a better insight of the data you are uploading.
I am excited to announce the launch of RSG pro. RSG pro is like RSG but you can upload up to 100.000 eyes. It is a great tool to use for quality control and get a good insight of your outcomes. There are plans for one month, 3 months and 1 year.
Of course you can test it all for free at the demo site where you can upload up to 20 eyes or play with the simulated 100 eyes dataset here.
The last update for RSG online adds the Target Induced astigmatism (TIA) vector vs Surgically Induced astigmatism (SIA) vector and the refractive astigmatism angle of error, with these two graphics you can now make eight of the nine standard graphics to report refractive surgery outcomes.
At this point there are no plans to make the nineth one (SE refraction stability), since that would need to add too many columns to the excel.
You can test the program here.
