3.5.5 Purkinje Measurement
3.5.5.1 Introducing the subjective refraction
To perform a Purkinje measurement, it is not necessary to have made a Best Focus
measurement. However, it is necessary to have introduced the subjective refraction
of the patient.
It is important to emphasize that, at the time of measurement, the patient:
•
Should not be corrected in any way: without their own or test glasses, without
cylindrical lenses in the head of the machine or contact lenses.
•
Must look at the laser whenever it is visible.
