Demonstration of the interval of the first eye and second eye surgeries. If the first eye and the second eye are self-comparison, score is 2. If patients’ characteristics are the same between the first eye and the second eye but no self-comparison, score is 1. If the characteristics are not compared without self-comparison, score is 0. Proportion of the excluded patients <10% and demonstration of excluded patients.
