Abstract
Background Pterygium is a common ocular surface lesion originating in the limbal conjunctiva. It has a high recurrence rate after excision; thus, there are multiple surgeries and adjuvant therapies to avoid this high recurrence rate. Aim The aim of this study is to demonstrate the effect of argon laser photocoagulation before and after surgery on primary pterygium recurrence. Patients and methods This study is a prospective interventional study that included a total of 20 eyes of 20 patients divided into two groups randomly: The follow-up period ranged between 6 and 15 months (mean: 10.5 months). Results The recurrence rate in group A was 20%, but in group B, it was 50%. However, it is still statistically insignificant (P=0.160); there was a highly significant difference between pterygium length on the cornea before and after treatment in recurrent cases in groups A and B, with shorter length in group A (P Conclusion Argon laser photocoagulation has benefits if used as adjuvant therapy to the bare sclera technique in pterygium excision as it decreases the recurrence rate. If recurrence occurs, the length of the recurrent pterygium on the cornea is less than the length preoperatively.
