我科自1986年7月开始在无角膜计的情况下应用软镜对100例192只眼的配镜体会和临床观察报告如下: 镜片来源:江苏省吴县光学仪器厂产品,为-3.0DS以下度数,镜片中心厚度在0.1—0.15mm的普通型软镜,镜片直径11—13mm,含水率42％。装配方法:按《角膜接触镜的临床应用》进行。因无角膜计,无从测定患者的角膜曲率半径,则按常人数据,选用7.7屈率半径,通过查阅《角膜顶点距离修正表》选出合适的镜片,一般矫正视力均能达到1.2—1.5。
Our department since July 1986 in the absence of keratometer application of soft-lens on 100 cases of 192 eyes of the mirror experience and clinical observations are as follows: Lens Source: Jiangsu Province, Wuxian optical instrument products, -3.0DS the following Degree, the thickness of the center of the lens 0.1-0.15mm common type of soft mirror, lens diameter 11-13mm, moisture content 42%. Assembly method: According to “the clinical application of contact lens”. Because of no keratometer, no determination of the patient’s corneal radius of curvature, then according to common data, the choice of 7.7 rate of decline rate, by consulting the “corneal apex distance correction table” to select the appropriate lens, the general correction of vision can reach 1.2-1.5.
