All this information is required because, on the basis of the artificial materials and their optical properties
present inside the eye, the instrument always corrects the measurements obtained to the most precise value
possible.
Once this information has been entered, you can access the acquisition environment.
For more details on the acquisition environment see the dedicated section.
The vitreous body nature is expressed, if different from natural, in the acquisition view as well as in the output
reports, as shown in the following figures. The lens nature is always reported.
