方法：随机双盲对照研究。收集2017-03/2018-03行手术治疗的单眼原发性鼻侧翼状胬肉患者90例90眼，分为A、B、C三组。A组角膜绷带镜+3g/L玻璃酸钠治疗； B组角膜绷带镜+1g/L玻璃酸钠治疗； C组：3g/L玻璃酸钠+包盖治疗。比较三组治疗后眼表刺激症状评分、角膜上皮愈合时间和结膜植片水肿消退时间。

结果：术后A组各观察时间点眼表刺激症状评分均低于C组(P<0.001)； A组角膜上皮愈合时间(2.08±0.78d)、结膜植片水肿消退时间(4.62±1.17d)均较C组(5.13±2.34、6.42±1.51d)明显缩短(P=0.001、0.002)。A组与B组术后各时间点眼表刺激症状以及结膜植片水肿消退时间均无差异(P>0.05)，但A组角膜上皮愈合时间明显缩短(P=0.018)。

结论：3g/L玻璃酸钠联合角膜绷带镜在翼状胬肉切除术后早期应用具有协同作用，可以有效缩短角膜上皮愈合时间，缓解刺激症状。

METHODS: In this double blind randomized controlled study, 90 eyes of 90 patients with unilateral primary nasal pterygium who underwent surgical treatment from March 2017 to March 2018 were sorted into three groups, named as group A, group B and group C. Group A was treated with +3g/L sodium hyaluronate eye dropsand corneal bandage contact lens; group B was treated with +1g/L sodium hyaluronate eye drops and corneal bandage contact lens; and group C with +3g/L sodium hyaluronate and patching. Ocular surface irritation symptom scores, corneal epithelial healing time and conjunctival graft edema subsidence time of the three groups were compared after treatment.

RESULTS: Ocular surface irritation symptom scores in group A were lower than those in group C at all observation time points postoperatively(all P<0.001); the corneal epithelial healing time(2.08±0.78d)and conjunctival graft edema subsidence time(4.62±1.17d)in group A were significantly shorter than those in group C with corneal epithelial healing time(5.13±2.34d)and conjunctival graft edema subsidence time(6.42±1.51d)(P=0.001, P=0.002). The corneal epithelial healing time was significantly shorterin group A when compared with group B(P=0.018), but there were no significant differences in ocular surface irritation symptom scores and conjunctival graft edema subsidence time between the two groups.

CONCLUSION: The combination of 3g/L sodium hyaluronate and corneal bandage contact lens has synergistic effect when applicated in the early stage after pterygium excision surgery, it can effectively shorten the corneal epithelial healing time as well as relieve irritation symptoms.
