Holding all else constant, the probability of achieving failure at any time point postoperatively with phaco alone was 3.40 times more likely than with phaco/MP-TSCPC (p = 0.005). Higher baseline IOP was found to be a statistically significant predictor of survival in comparing phaco/MP-TSCPC and phaco alone, with a one unit increase in baseline IOP reducing the hazard of clinical failure at any point in time by 9% (p = 0.022)
