Abstract

PURPOSE
To compare and analyze the clinical outcomes after the traditional mini-flap technique and a new modified mini-flap technique for pterygium surgery. METHODS: This is a retrospective, clinical outcome study of 39 eyes that received the existing mini-flap technique from January, 2004 to August, 2005, and 142 eyes that received the modified mini-flap technique from September, 2008 to December, 2010. We analyzed the recurrence rate of each mini-flap technique and the difference between the group that experienced recurrence and the group that did not. We also analyzed the difference between the group that received the mini-flap technique and the group that received the modified mini-flap technique. RESULTS: The recurrence rate of pterygium patients who received the mini-flap technique was 10.3% (4/39). The rate of those who received the modified mini-flap technique was 2.1% (3/142), which is statistically lower (p = 0.040). However, compared from the recurrence rate of 6.1% (3/49) that was reported in 2008, the recurrence rate of the modified mini-flap technique did not show any statistical significance (p = 0.165). From the comparison of demographic factors of the patients in each surgical technique group, in both recurred and not recurred group, the patient group in the modified mini-flap technique group whose pterygium was recurrd was the youngest (p < 0.001). CONCLUSIONS: The newly applied modified mini-flap technique is not only a safe method with low recurrence rate compared to the traditional mini-flap technique, but also a reliable surgical technique in both primary and recurred pterygium.
