What is Goniotrans?

Simple tool to reference angles

digital angle conveyor

GonioTrans is a useful, free and yet simple tool based on a virtual angle conveyor to annotate the angular position of the ocular structures based on a picture of the eye. After capturing a picture of the eye, it is copied and stored in the program, that overlays a pattern that simulates an angle conveyor with two overlaying hemi-meridians with marks from 0° to 180°, using steps of 5° or 10°.

The appropriate meridians for incisions, the marks for toric lens, etc. can be determined precisely thanks to referrers like nevus or iris crypts, aqueous veins, etc. In the same way this allows to check the lens position and stability, incisional axes, etc.

It's very easy to use, it runs on Microsoft Windows PC, iOS and Android Devices.
