Embodiment Construction
[0037] figure 1 An optical system with wide angle optics and a shift lens for an ophthalmic implant of an embodiment of the manual adjustment system is shown in cross-sectional view. The refractive power adjustment of the optical system is realized in the illustrated embodiment with a three-lens system comprising a lens system 2 with higher angular accommodation, a shift lens 3 and an additional lens 4 with a common optical axis 5 . In the example the biconcave shift lens is movable along the optical axis relative to the lens system and the supplementary lens. The supplementary lens ensures a patient-specific basic refractive power of the optical system and thus of the ophthalmic implant, allows compensation of deviations and serves as an access exit window of the adjustment system to the vitreous of the eye. The optical system shown comprises an optical assembly with lens system 2, which increases the angle of the three-lens optical system required for adjusting the desired ...
