Greetings, fellow ophthalmologists

We're in the midst of changing everything as far as IOL power calculations are concerned.

There will be at least two new strategies to calculate IOL power soon. We're waiting for the 

clinical data to be available before we launch these.

In the meantime, we're removing the older calculator versions. Stay tuned.

Calculate Surgically Induced Astigmatism for upto 200 cases at a go. The perfect SIA Calculator for academic use.
