I have found toric IOLs invaluable for managing astigmatism for my cataract patients. The online calculators are great, but do require you to be in front of a computer to choose the lens and don’t easily allow you to try different wound locations or astigmatic combinations.
EyeToric allows you to dynamically change the wound position to see the effect on lens power and placement.
For anyone who has worked at a hospital where not all toric powers are routinely stocked, occasionally the lens you want is not available, or you have enlarged the main wound and need to compensate for greater astigmatism – EyeToric has this covered. It is possible to change the predicted lens power and axis placement and see the effects this has on postop astigmatism.
If you get an unexpected postop result you are able to determine if this is due to unexpected lens positioning or inaccurate preop Ks – useful in planning further surgery.
I think the application is quite intuitive, particularly if you have used the online calculator. Feedback is welcome.

Lens Database updated to most recent constants at http://ocusoft.de/ulib/c1.htm.
Two databases are now available to update online at http://eyeapps.com.au/lensdata.txt (ULIB database)
and a seperate toric database (http://eyeapps.com.au/toricdata.txt. It is possible for the user to point to their own databases (in JSON format).
A tolerance arc is displayed to show the "wriggle room" for toric placement. Set at 1D of astigmatism (can be changed in app settings).
Improved access to IOLMaster database.
Multiple bug fixes.
Ratings and Reviews
Functional and useful
The calculator works as promised, and is useful for on the go toric calculation. Not going to win any beauty pageants, but that's okay. Thanks for making this tool available!
Note that it is by default more aggressive than the Alcon web based one; for a patient I tried it with recently, by recommending a T6 it targeted 0.05 dippers of residual cyl (a slight overshoot) rather than the 0.54 diopters the online calculator left in the original axis by choosing a T5. A slider lets you adjust residual cyl to your own threshold.
This app was extremely helpful understanding an off axis T8 toric iol
