Effect of Modified Pedicle Conjunctival Flap Transposition Combined with Surgical Resection in the Treatment of Pterygium and its Effect on Tear Film Function and Visual Acuity Level
Objective To study the effect of modified pedicle conjunctival flap transposition combined with surgical resection on patients with pterygium and its effect on tear film function and visual acuity level.Methods Sixty patients with pterygium admitted to the Department of Ophthalmology&Otorhinolaryngology,Yiyang County People's Hospital from December 2020 to December 2022 were selected and divided into control group(30patients)and observation group(30 patients)by random number table method.The control group was treated with surgical resection,and the observation group was treated with modified pedicle conjunctival flap transposition on the basis of the control group.The surgical efficacy,tear film function[tear film rupture time(BUT),basic tear secretion test(SIT)],corneal index(corneal horizontal curvature,corneal vertical curvature,corneal astigmatism),visual acuity level and postoperative recurrence were compared between the two groups.Results The excellent and good rate of treatment in the observation group was higher than that in the control group(P＜0.05).The BUT and SIT of the two groups at 6 months after operation were greater than those before operation,and the BUT and SIT of the observation group were greater than those of the control group(P＜0.05).The corneal horizontal curvature and corneal vertical curvature of the two groups at 6 months after operation were greater than those before operation,the corneal astigmatism was smaller than that before operation,andthe corneal horizontal curvature and corneal vertical curvature of the observation group were greater than those of the control group,the corneal astigmatism was smaller than that of the control group(P＜0.05).The visual acuity of the two groups at 1 week after operation was higher than that before operation(P＜0.05).The visual acuity level of the observation group was higher than that of the control group at 1 month after operation(P＜0.05).The recurrence rate of the observation group was lower than that of the control group at 6 months after operation(P＜0.05).Conclusion Modified pedicle conjunctival flap transposition combined with surgical resection is effective in the treatment of pterygium,which can improve the tear film function,correct the corneal degree,accelerate the recovery of visual acuity level and reduce the risk of postoperative recurrence.
