摘要：
A method, system and apparatus for vision correction are disclosed. The method, system and apparatus include a toric intraocular element for correcting astigmatism and having a cylinder power, and a depth of focus extender coupled to the toric intraocular element, the depth of focus extender extending a depth of focus. The extended depth of focus may reduce sensitivity of the toric intraocular element to at least one of rotation and selected cylinder power.
