Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To describe and compare the acquisition rate between different biometers in eyes To describe and compare the acquisition success rate between different biometers in eyes with advanced cataracts | 6 months | Acquision succes rate is indicated by a percentage, from 0% to 100%. The biometer can obtain (success) or not (failure) the measurement. This value will be indicated for each biometer. |
Secondary
| Measure | Time frame |
|---|---|
| To describe the correlation of success rate and Dysfunctional Lens Index (DLI, iTrace) | 6 months |
