目的 :探讨以微量美蓝着色前囊膜提高白色白内障前囊在术中的辨别率的可行性和技术方法。方法 :前房内注入消毒空气 ,水分离针抽取 1%美蓝注射剂 0 0 1ml,注入前囊中央表面 ,轻轻磨擦 30s ,粘弹剂置换出空气 ,撕囊镊完成连续环形撕囊术。结果 :32例 39只眼中 35只眼获得圆形或类圆形撕囊口 ,占 89 7% ,3只眼产生 1个方位放射状裂口 ,1只眼产生 2个方位放射状裂口 ,术后未见明显前房反应和裂隙灯显微镜下所见的内皮反应。结论 :微量美蓝前囊染色可安全有效地应用于白色白内障连续环形撕囊术中 ,但必须注意操作技巧。
Objective: To explore the feasibility and technical method of improving the resolution of the anterior capsule of white cataract with a small amount of methylene blue before staining. Methods: Sterile air was infused into the anterior chamber, and 0% 1ml of methylene blue injection was injected into the water separation needle. The central cavity was injected into the central surface of the anterior capsule and gently rubbed for 30s. The viscoelastic agent was used to replace the air and the capsulotomy forceps were used to complete the continuous circular capsulorhexis. Results: Of 32 eyes (39 eyes), 35 eyes had circular or round capsulorhexis, accounting for 89.7%. Three eyes had one radial radial incision, and one eye had two radial radial incisions without postoperative Obvious anterior chamber reaction and slit lamp microscopic examination of the endothelial response. CONCLUSION: Trace minilage anterior pouch staining can safely and effectively be applied in the treatment of white cataract with continuous circumcaval capsulotomy, but care must be taken in handling techniques.
