当无晶体眼的散光不超过2.00D时,可用角膜表面镜片术矫正;而当散光度较高时,可在施行角膜表面镜片术的同时行环形角膜切开术,以降低角膜散光度。作者等用这种方法矫正无晶体眼及同时井发的散光(散光度为5.00～6.00D),且取得术后满意的效果。极高度的散光,若发生于穿透性角膜移植术者,要行角膜表面镜片术矫正无晶体眼会有很大困难。迄今为止,若在角膜移植术时或术后不能植入人工晶体,通常是由于眼内缺乏正常的解剖支撑,或有虹膜粘连。这时若伴有的
When the astigmatism of the astigmatism does not exceed 2.00D, the available corneal surface lens surgery; and when the astigmatism is high, the corneal surface lens surgery can be performed at the same time, corneal ring surgery to reduce corneal astigmatism. The authors used this method to correct aphakia and at the same time well astigmatism (astigmatism 5.00 ~ 6.00D), and achieved satisfactory results. A very high degree of astigmatism, if occurred in penetrating keratoplasty, corneal surface lens surgery to correct aphakia will be very difficult. To date, if intraocular lenses can not be implanted during or after corneal transplantation, it is usually due to a lack of normal anatomic support in the eye or iris adhesion. If accompanied by this time
