Abstract

Objective: The aim was to compare the recurrence rate and complications after primary pterygium surgery using intraoperative 0.02% concentration of mitomycin C between 2 minutes and 3 minutes.

Methods: In this two-group quasi-experimental research, we evaluated patients with primary pterygium who underwent pterygium surgery with intraoperative 0.02% concentration of mitomycin C, between 2 minutes and 3 minutes, at Hua Hin Hospital between March 2021 and September 2022. The 60 patients were randomly divided into 2 groups, (n = 30). One group underwent pterygium surgery using 2-minute 0.02% concentration of mitomycin C and the other one was subjected to 3-minute 0.02% concentration of mitomycin C. Data were analyzed through descriptive statistics (frequency, percentage, mean, standard deviation) and inferential statistics (chi-square test, independent t test, relative risk).

Results: Both groups had same demographic data. The recurrence rate after primary pterygium surgery using an intraoperative 0.02% concentration of mitomycin C between 2 minutes and 3 minutes were 3.3% and 10% respectively. There were no significant differences in the recurrence rate and complications between the 2 groups.

Conclusions: From the research results, intraoperative 2-minute 0.02% concentration of mitomycin C should be used in the treatment of pterygium because of a low recurrence rate and complications; moreover, it is a safe and convinient method.
