TORIC INTRAOCULAR LENS WITH MODIFIED POWER CHARACTERISTICS
摘要
An intraocular lens for correcting or reducing the astigmatism of a cornea includes an optical element that has optical properties and characteristics that make it tolerant of rotational misalignment, when compared to a comparable lens having a uniform astigmatism orientation across its entire optical element, leading to more relaxed tolerances for a surgeon that implants the lens. The optical element of the toric ophthalmic lens has meridians associated therewith, including a high power meridian and a low power meridian orthogonal to the high power meridian. The optical element has at least one radially modulated meridian along which power monotonically varies with increasing radial position.
