- Primary Outcome Measures
Name Time Method Distance visual acuity: It will be measured at a distance of 6 meters and adjusted to infinity.
- Secondary Outcome Measures
Name Time Method Ocular biometry: it will be performed using the two ocular biometers of the study (both with CE marking) on each patient following the procedure of use indicated in the manual for each equipment. This measurement, of short duration, provides information on the K, CCT, ACD, LT, WTW and AL of the eye. Three measurements will be carried out for each biometer, being the first one or the other in a randomized basis indicated by a randomization software.
