翼状胬肉不同手术方式的术前术后屈光变化观察

Refractive changes comparison of pre-and post-operation in different pterygium surgery

目的:回顾分析原发性翼状胬肉不同手术方式前后视力及眼屈光度的改变。方法:初发翼状胬肉24例24眼随机分为两组,均侵犯角膜3～4mm,一组行翼状胬肉切除联合自体球结膜移植,一组行翼状胬肉切除联合生物羊膜移植,分别比较术前术后屈光度的差异及裸眼视力的变化。结果:自体球结膜移植组术前术后裸眼视力及散光变化有统计学意义(P<0.05)。生物羊膜移植组术前术后裸眼视力及散光变化有统计学意义(P<0.05)。结论:翼状胬肉导致的眼球屈光不正以远视散光为主,两种手术治疗均可以降低散光,提高视力。

AIM：To analysis the refractive and ocular vision acuity changes of pre-and post-operation in different pterygium surgery.METHODS：A total of 24 eyes with primary pterygium were included in the study;12 eyes underwent pterygium excision and amnioticmembrane transplantation surgery;12 eyes underwent pterygium excision and conjunctival autograft transplantation surgery. Astigmatism and un-correctedvision acuity of pre-and post-operation were observed.RESULTS：In both groups, the astigmatism and visul acuity but not with hyperopia had statistic significance in pre-and post-operation.CONCLUSION：The refractive change in pterygium is hyperopia astigmatism,both pterygium excision and amnioticmembrane or conjunctival autograft transplantation surgery can low astigmatism degree and improve the visual acuity accordingly.
