Toric IOL axis

As an Ophthalmologist I have used this app on an almost daily basis to measure the exact axis of a Toric IOL in the post op period. It is accurate to 1 degree in the clinic and is essential to obtain the IOL axis especially for input in the Berdahl/Hardten Astigmatism Fix calculator to evaluate if a Toric IOL should be rotated. Just sit patient at slit lamp. Have them look into the beam. Rotate the beam to align with the IOL axis. Have patient sit back and hold cell phone up to the slit lamp and adjust the axis line in the app to be coincident with the slit beam while looking through the slit lamp. Extremely accurate and fast. Congratulations to the authors of this most useful medical tool.

Toric IOL helper

Useful tool to record axis of an IOL in situ when your slit lamp doesn’t have a protractor. Also useful to plan manual AK arcs by entering the axis and arc length.
