The project topic is the scientific examination of the optical properties of implanted intraocular lens (IOL) provided for cataract patients and related production technology development. The goal is to provide patients with implanted artificial eye lens with an optical performance that reaches the healthy eye visual ability. The modelling of the lens in a realistic eye model, the development of new diagnostic procedures and measurement of the errors of the lens mapping, light scattering properties and testing of accommodative power is required.
