Developing a Measure to Quantify Ocular Pain Postoperatively: The Adaptation of the Ocular Pain Assessment Survey

Table 1

The statistics of the answers given to pre, post, and late-postsurveys. Each section is evaluated from 0 to 10. The final section on pain relief is not included since it is only tested in the late-postsurvey. Overall significance is measured statistically via the Friedman test, whereas individual significances are calculated using Wilcoxon signed rank test. P1 is the significance between presurvey and postsurvey where P2 is the significance between post and late-postsurveys and P3 is the significance between pre and late-postsurvey. Bonferroni adjustment is made to determine the significance of the three surveys (significance <0.05/3).
