For a single ray passing multiple surfaces the calculation cannot be performed by analytical formulae, because otherways so-called "transcendental equations" occur which are unsolvable for principal mathematical reasons. Instead of an analytical calculation OKULIX
solves the problem by numerical methods.
OKULIX is a program for the calculation of the monochromatic optical properties of the human eye. The designated use in the sense of the CE-rules is the adaptation of intraocular lenses (IOL) and the calculation of ablation profiles for the refractive laser surgery. Users of OKULIX are ophthalmologists.
Other applications are not conform with the product designation.
OKULIX complies with the requirements for european medical products 93/42/EWG and is labelled with the CE sign for a class I medical product.
