In forming a special contact lens for use in cases of keratoconus, the centre the curves vary from 7.2 mm (47 dioptres) to 5.6 mm (60 dioptres), and at the periphery the curve is a constant 7.65 mm (44 dioptres) in all lenses. This special lens has the following advantages: (1) It protects the cornea: (2) It exerts a strong analgesic effect; (3) Vision is improved in 26% of cases from 0.03 to 0.6 and in 43% from 0.03 to 0.8. (4) Ophthalmometry gives equal values of about 69% and keratometry equal values of about 19%. The lenses may be made from PMMA, HEMA, CAB, and Polycon. The HEMA lenses did not correct the visual acuity, but those made with CAB and later with Polycon gave highly satisfactory results.
在制作用于圆锥角膜病例的特殊隐形眼镜时，镜片中心的曲率从7.2毫米（47屈光度）到5.6毫米（60屈光度）不等，而在周边，所有镜片的曲率恒定为7.65毫米（44屈光度）。这种特殊镜片具有以下优点：（1）它能保护角膜；（2）具有很强的止痛效果；（3）26%的病例视力从0.03提高到0.6，43%的病例从0.03提高到0.8。（4）眼压测量约69%的数值相等，角膜曲率测量约19%的数值相等。这些镜片可以由聚甲基丙烯酸甲酯（PMMA）、甲基丙烯酸羟乙酯（HEMA）、醋酸丁酸纤维素（CAB）和聚康（Polycon）制成。HEMA镜片不能矫正视力，但由CAB以及后来由聚康制成的镜片取得了非常令人满意的效果。
