不同翼状胬肉手术方式对角膜屈光的影响

目的:探讨原发性翼状胬肉不同手术方式对角膜屈光的影响。方法:单侧原发性翼状胬肉43例43眼,随机分为两组,A组行翼状胬肉切除联合自体球结膜移植21例21眼;B组行翼状胬肉切除联合角膜缘干细胞移植22例22眼。两组均行术前及术后2wk的裸眼视力、角膜曲率和角膜散光的检测,进行比较分析。结果:两组术后2wk的裸眼视力、角膜曲率和角膜散光与术前比较差异具有统计学意义(P<0.05);而两组相比,术后2wk的差异无统计学意义(P>0.05)。结论:翼状胬肉手术可使角膜屈光改变,两种手术均可以提高视力,降低散光。

Effect of different surgeries for pterygium on corneal refraction

·AIM:To evaluate the changes of corneal refraction after different pterygium surgery.·METHODS:A total of 43 eyes with primary pterygium were included in the study;They were divided into 2 groups:pterygium excision with conjunctival autograft transpIantation performed in A group(21 cases 21 eyes),pterygium excision with corneal limbal stem cell transplantation performed in B group(22 cases 22 eyes).Naked visual acuity,corneal curvature and corneal astigmatism were measured and compared in preoperative,postoperative 2 weeks.·RESULTS:In group A and B,the results of naked visual acuity,corneal curvature and corneal astigmatism in postoperative 2 weeks were different to that of preoperative with statistical significance.While the changes in postoperative 2 weeks had no statistical singificance difference between two groups.·CONCLUSION:The surgery for pterygium can change the corneal refraction.Both pterygium excision with conjunctival autograft transplantation and pterygium excision with limbal stem cell transplantation can decrease astigmatism degree and improve visual acuity.·
