AIM:To investigate the surgical method to reduce the recurrence of pterygium·METHODS: Totally 95 cases(110 eyes) were randomly divided into two groups.A group of 55 cases(63 eyes) used reverse method to separate pterygium,combined with mitomycin C(MMC) and autologous conjunctival flap transplantation intraoperatively.B group of 40 cases(47eyes) used conventional surgery.Recurrence rates and corneal epithelial healing time were observed·RESULTS:Followed up for 6-12 months,A group recurrence rate was 3.2%;B group recurrence rate was 36.2%,the difference was statistically significant(χ2 =9.57,P<0.01).Corneal epithelial wound healing time:average 4.6±1.2 days in A group,average 8.1±0.9 days in B group,the difference between the two groups was statistically significant(t=13.08,P <0.01) CONCLUSION:Reverse method combined with MMC and autologous conjunctival flap transplantation in the treatment of pterygium is convenient in drawing material,easy to learn,and with the advantages of faster recovery of corneal wound,calm conjunctiva,low recurrence rate and definite effect,which is an ideal surgical way and worth promoting in primary hospitals.
