Figure 14. Entering the refraction, with information already entered
The instrument is able to correct automatically the equivalent refractions (spherical
refr cylindrical refraction/2) within the range of +5D to -8D, as long as the
astigmatism is less than or equal to 0.5D. In any other situation, the instrument
requires external assistance. This may be:
- Cylindrical corrective lenses, located in the head of the unit.
- Glasses or trial frames.
- Contact lenses.
The program itself, depending on the information entered, will display how both
patient’s eyes can be corrected, hiding the corrective modes that do not apply, and
highlighting the most recommended mode.
