在近视眼的发生与发展中,巩膜变弱起主要作用。由此,可应用巩膜加固术来治疗高度近视眼。此类手术原则上分为两型:①移植片通过眼球后极,与前后轴垂直,从而使前后轴缩短。②移植片加固赤道部。前法操作复杂,且有并发症;后法移植片常不能遮盖眼球的后极部。高度近视眼眼球的后外部份伸延最长,因而应用巩膜成形术加固眼球的这一部分最为合理。作者设计的新方法有以下特点:①首先加固眼球的后外段,因该处对抗变形的抵抗力最低;②移植物取自巩膜,易于贴附眼球表面,能很好遮盖受体眼;③移植片(巩膜条)中央呈壶腹状,能很好遮盖眼球后外段部份;④术中为计算眼球的个体数据,特按专门设计图确定移植片前端与角
In the occurrence and development of myopia, scleral weakening plays a major role. Thus, scleral reinforcement can be applied to treat high myopia. In principle, these types of surgery are divided into two types: ① the posterior pole of the ocular graft, perpendicular to the anterior and posterior axes, so that the anterior and posterior axis shortened. ② graft reinforcement equator. The former method is complicated to operate and has complications. The posterior pole graft often can not cover the posterior pole of the eyeball. The eyeballs after high myopia extension of the outer part of the longest, so the use of scleral buckling to strengthen the eye of this part of the most reasonable. The new method designed by the author has the following characteristics: Firstly, the posterior outer segment of the eyeball is reinforced because the resistance against deformation is the lowest; ② the graft is taken from the sclera and easily attached to the surface of the eyeball so as to cover the eye of the recipient well; Transplantation (sclera) in the middle of the ampulla, can cover the outer part of the eye very well; ④ Intraoperative surgery to calculate the individual eyeball data, especially by special design drawings to determine the front and the angle of the graft
