Abstract

Background: The rotational conjuctival flap technique in primary pterygium surgery has been studied before with positive outcomes in terms of aesthetics and recurrence rate. Based on this, we have studied and made improvements in the double conjunctival flap rotation technique in order to simplify the surgical process as well as increase the effectiveness of treatment for patients with pterygium. Objective: 1. To investigate clinical features of pterygium. 2. To evaluate the results of pterygium treatment by rotating double conjunctival flaps. Methods: Descriptive, prospective, clinical trial on 41 eyes of 36 primary pterygium patients who were treated with double - rotating conjunctival flaps surgery at the ENT - Eye - Odontology Department, Hue University of Medicine and Pharmacy Hospital. Patients were followed up at postoperative day 1, 7; 1st month and 3rd month. Results: Grade II and III pterygium accounted for the majority, the intermediate clinical morphology comprised 56.1% of cases. The mean postoperative visual acuity was 0.66 ± 0.23D (the preoperative VA was 0.54 ± 0.28D). Astigmatism decreased from 1.23 ± 0.83D preoperatively to 0.98 ± 0.59D after 1 month and 0.71 ± 0.54D after 3 months of surgery. Kf index of pterygium grade III and IV after surgery increased statistically significantly with p < 0.05. 40/41 eyes in the study (97.56%) achieved good cosmetic results. No case of recurrence was recorded 3 months after surgery. Conclusions: The initial research of the double conjunctival flap rotation has achieved good results in terms of aesthetics, function, few complications, low recurrence rate.
