近年来国外关于放射状角膜切开术的报告逐渐减少，原因之一是放射状角膜切开术存在一定局限性（包括副作用）。随着新技术不断的发展，研究工作多转向其它手术，如准分子激光屈光性角膜切削术等。然而在我国放射状角膜切开术似有方兴未艾之势，对此作者认为进一步了解国外已有的关于放射状角膜切开术副作用的资料颇有助益，于是在前次综述（参见本刊１４（２），１９９０）的基础上特就１９９０年以来的新资料作一介绍。 In recent years, foreign reports of radial keratotomies have been gradually reduced. One of the reasons for this is that radial keratotomies have some limitations (including side effects). With the continuous development of new technologies, research has shifted to other surgery, such as excimer laser refractive keratotomy. However, radial keratotomy in our country seems to be in the ascendant. To this, the author thinks that it is helpful to know more about the existing foreign data on the side effects of radial keratotomy. Therefore, in the previous review ), 1990) on the basis of special new information since 1990 to make an introduction.
