Long-term in vivo experiments shown are a variations between the estimated and measured pump outflow over 95Â days, b the correlation between the estimated and measured pump outflow, c the error rate during early period from 0 to 30Â days after the operation, d the error rate during middle period from 31 to 60Â days and e the error rate during final period over 61Â days
