4. Optimizes very high axial length to Wang & Koch optimized Axial Length values ( it has integrated W&K nomogram and you do not need to hunt for one )

5. It validates the Pupil and Iris barycenters for multifocal lenses (with integrated builtin formulas).

6 Provides you colour codes so that your biometrician and optometrists are aware when out of bound values are keyed in.
