Viscoat黏弹剂联合软性角膜接触镜治疗角膜中央穿孔

Viscoat viscoelastic combined with soft corneal contact lens for central corneal perforation

目的探讨Viscoat黏弹剂联合软性角膜接触镜治疗角膜中央穿孔的临床疗效。方法收集我院眼科就诊的6例角膜中央穿孔患者的临床资料,角膜穿孔的直径均不超过2.0 mm,行角膜局部清创并在前房内注入Viscoat,然后予以配戴软性角膜接触镜,随访2~3个月,记录患者主观感觉、视力、裂隙灯检查、眼压、活体共聚焦显微镜、角膜内皮细胞计数等以判断疗效。结果所有病例均达到治愈,治疗时长为1~2个月;最佳矫正视力提高至0.6~0.8,角膜内皮细胞计数为(3415.5±279.5)个·mm-2,角膜未留明显瘢痕,无严重并发症发生。结论对于直径≤2.0 mm的外伤性角膜中央穿孔可通过应用Viscoat黏弹剂联合软性角膜接触镜治疗,预后良好,并且减轻了患者的经济负担。

Objective To investigate the clinical effects of the Viscoat viscoelastic combined with soft corneal contact lens for central corneal perforation.Methods Six cases were collected and treated with corneal local debridement of which diameter were less than 2.0 mm.Six cases received Viscoat viscoelastic injection into their anterior chamber.And then soft corneal contact lens were worn.The curative effect indicators such as patients’ symptom,visual acuity,slit lamp examination,intraocular pressure,confocal microscope and corneal endothelial cell counts were recorded in the follow-up periods.Results All the cases were healed with the recovery time of 1 month to 2 months;After treatment,the best corrected visual acuity of patients were increased to 0.6-0.8 and average corneal endothelial cell count was （3415.5±279.5）mm-2.No obvious scar was left in the cornea and no serious complications occurred during treatment.Conclusion For traumatic corneal central perforation with diameter is 2.0 mm or less can be treated with Viscoat viscoelastic combined with soft corneal contact lens.This therapy is worthy of popularize since it’s satisfied prognosis and less economic burden.
