Case complexity index (Posterior Capsular Rupture)

What this data shows:

This is the overall predicted probability of PCR occurring based on the supplied case complexity data.

How the data is gathered:

This estimate is derived from the supplied case complexity data, if a centre does not accurately record the case complexity data for their operations this will impact on this estimate.

When the data is shown:

As the estimate is the overall probability of PCR occurring, and is derived from the supplied case complexity data, this can be interpreted as the higher the value, the more complex the surgery a centre or surgeon has performed.

More information about the data source:
