Method e.g. for intraocular lens for cataract treatment, involves determining desired refractive power of lens and determining correlation of seminal force in air Abbe-refractometer with measured refractive index

The method involves determining initial information such as the desired refractive power of the intraocular lens to be produced in-situ. Due to the geometric ratio, a determination is made of the correlation of the seminal force in an air Abbe-refractometer with a measured refractive index and using...

Zusammenfassung:	The method involves determining initial information such as the desired refractive power of the intraocular lens to be produced in-situ. Due to the geometric ratio, a determination is made of the correlation of the seminal force in an air Abbe-refractometer with a measured refractive index and using a water chamber. The wavelength used corresponds to the green mercury line and being present at a temperature of 35 degrees. The refractive index of the water chamber that is taken has a value between 1.3345 and 1.3349, preferably with a value of 1.3347.
