    • A method of cleaning deposited material from a molding surface (10) of a mold (1) for forming ophthalmic lenses comprises the steps of: - bringing a cleaning head (20) into contact with the molding surface (10), the rotational axis (22) of the cleaning head (20) being arranged normal to the molding surface (10), - rotating (220) the cleaning head (20) around the rotational axis (22) while maintaining the contact between the cleaning head (20) and the molding surface (10), - moving the cleaning head (20) to perform a precession motion (110) around a central normal (11) on the molding surface (10), while rotating (220) the cleaning head (20) around the rotational axis (22) and while maintaining the contact between the cleaning head (20) and the molding surface (10). During the precession motion (110) the rotational axis (22) includes an inclination angle (α 1 ,α 2 ) with the central normal (11) on the molding surface (10).
    • 从用于形成眼镜片的模具(1)的模制表面(10)清除沉积材料的方法包括以下步骤: - 使清洁头(20)与模制表面(10),旋转轴线 清洁头(20)的垂直于模制表面(10)布置, - 围绕旋转轴线(22)旋转(220)清洁头(220),同时保持清洁头(20)和 所述模制表面(10), - 围绕所述模制表面(10)上的中心法线(11)移动所述清洁头(20)以执行进动运动(110),同时围绕所述清洁头(20)旋转(220) 旋转轴线(22)并且同时保持清洁头(20)和成型表面(10)之间的接触。 在进动运动(110)期间,旋转轴线(22)包括与成型表面(10)上的中心法线(11)的倾斜角(α1,α2)。
