摘要
目的 探讨放射状角膜切开治疗急性水肿期圆锥角膜的临床效果。方法 对急性水肿期圆锥角膜共12例 (12只眼 ) ,采用深度为 0 .6～ 0 .6 5 mm角膜切开刀 ,在角膜水肿区域行 6～ 8条放射状角膜切开 ,术后 7天、1、3、6个月分别观察角膜形态及视力效果。结果 急性水肿期圆锥角膜术后 7天角膜仍然水肿 ,切口微张 ,切开处角膜渗水 ,角膜水肿减退 ,1个月切口闭合 ,无角膜渗水 ,3个月角膜无水肿 ,相应处可见后弹力膜破裂灰白色疤痕 ,视力 0 .1～ 0 .6。结论 对急性水肿期圆锥角膜行放射状角膜切开可以改善角膜症状 ,提高视力 。
Objective To investigate the clinical effect of radial keratony for keratoconus with edema.Methods Radial keratome of 0.6～0.65 mm was used to cut 6 to 8 radial incisions on edematous area on 12 cases (12 eyes) with keratoconus during edema period.The conformation of cornea and visual acuity were observed at 7 days,1,3 and 6 months postoperatively.Results The cornea was still edematous and the incisions opened slightly with water escape after 7 days.At 1 month postoperatively,the edema subsided and the incisions closed without water eacape.After 3 months,the edema was disappeared while achlys were left on the incisions and the posterior elastic membrane.The visual acuity achieved 0.1 to 0.6.Conclusion Radial keratomy for keratoconus with edema can be a emergent method to condition the symptom of cornea before penetrating keratoplasty,and can improve the visual acuity.
