背景技术Background technique
板层角膜移植术，是一种部分厚度的角膜移植。手术时仅切除角膜前面的病变组织，再移植以部分厚度的透明角膜供体，修补切除区域。术后发生免疫排斥的几率较低。临床常用于治疗中浅层角膜混浊、角膜营养不良性混浊、圆锥角膜、角膜中浅层感染、角膜肿瘤等。Lamellar keratoplasty is a partial-thickness corneal transplant. During the operation, only the diseased tissue in front of the cornea is resected, and then a part-thick transparent corneal donor is transplanted to repair the resected area. The chance of immune rejection after surgery is low. Clinically, it is commonly used in the treatment of superficial corneal opacity, corneal dystrophic opacity, keratoconus, superficial corneal infection, corneal tumor, etc.
板层角膜移植术可及时去除病灶，术中病灶处理彻底，易于控制炎症，保住眼球，为再次增视性角膜移植术创造条件。手术无须切开前房，很少发生浅前房及眼内感染等术后并发症。手术面积不受限制，可做任何形式包括部分巩膜在内的全板层移植。由于没有内皮细胞，板层移植排斥反应的发生率一般仅为4～5％。Lamellar keratoplasty can remove the lesions in time, the lesions can be treated thoroughly during the operation, the inflammation can be easily controlled, the eyeball can be preserved, and conditions can be created for another vision-enhancing keratoplasty. The operation does not need to cut the anterior chamber, and postoperative complications such as shallow anterior chamber and intraocular infection rarely occur. The operation area is not limited, and any form of full lamellar transplantation including partial sclera can be done. Due to the absence of endothelial cells, the incidence of lamellar graft rejection is generally only 4 to 5%.
现有的板层角膜移植术中常采用手术刀撑开板层角膜，手术刀力道不容易控制，稳定性差，容易造成手术偏差，危害人体眼部健康。In the existing lamellar keratoplasty, a scalpel is often used to stretch the lamellar cornea. The force of the scalpel is not easy to control, the stability is poor, and it is easy to cause surgical deviation and endanger human eye health.
