以计算机、激光技术为基础的准分子激光手术,给眼科手术带来了一场革命性的改变。目前,已有100万例以上患者接受了准分子激光屈光性角膜手术。经过一段时间的观察,人们已逐渐消除了对手术疗效和安全性的怀疑。但是,临床经验表明:准分子激光近视治疗系统虽由计算机控制,如要取得良好的手术效果,仍然受到很多人为因素的影响。首先,由于手术的基本原理是对屈光度稳定的患者进行角膜前表面的切削,以降低角膜前表面屈光能力和整个眼球的屈光度,因此患者本身屈光度的稳定将是决定性的因素。18周岁以下的患者,由于屈光度尚未稳定而不宜手术。18周岁以上的患者屈光度也应当稳定2年以上方能接受手术。
Excimer laser surgery based on computer and laser technology has brought a revolutionary change to ophthalmic surgery. At present, more than one million patients have undergone excimer laser refractive corneal surgery. After a period of observation, people have gradually eliminated the suspicion of the efficacy and safety of surgery. However, clinical experience shows that: Although the excimer laser myopia treatment system controlled by the computer, to obtain good surgical results, still subject to many human factors. First, since the basic principle of surgery is to cut the anterior corneal surface of a patient with stable diopter to reduce the corneal anterior refractive power and the refractive power of the entire eyeball, stabilization of the patient’s own diopter will be the decisive factor. Patients under 18 years of age due to the instability of the refraction is not suitable for surgery. Patients over 18 years of age should also be stable in more than 2 years before surgery.
