Effect observation of pterygium excision with limbal-conjunctival flap surgery

Objective To observe the curative effect of pterygium excision with limbal-conjunctival flap surgery.Methods 29 cases(30 eyes) patiemts with pterygium,all patients were given pterygium excision with limbal-conjunctival flap surgery,after treatment,observed the corneal epithelial healing time,visual acuity level,tracked pterygium recurrence and analyzed complications.Results Among 29 cases patients in the postoperative 3 ～ 4d corneal epithelial repair 27 cases(29 eyes),20d after corneal epithelial repair 2 cases(2 eyes).Appeared lobe hemorrhage 3 cases(3 eyes).All patients with conjunctival flap edema after treatment for 10 ～ 14d,lobe hemorrhage absorption after treatment for 10d,conjunctival hyperemia subsided gradually after treatment for 15d.Pterygium recurrenced 2 cases(2 eyes),the recurrence rate was 6.5%,the remaining 27 cases(29 eyes) conjunctival flap healing formation after treatment for 1 month,graft boundary confusion,followed three years of no change,pterygium cured.After treatment for 3 months,the visual acuity(0.61±0.17) was higher than before treatment(0.34±0.14),the difference was statistically significant(P0.05).Conclusion Pterygium excision with limbalconjunctival flap transplantation is an ideal method for the treatment of pterygium,reducing the recurrence,and worthy of clinical application.
