TORIC LENS WITH DECREASED SENSITIVITY TO CYLINDER POWER AND ROTATION AND METHOD OF USING THE SAME

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.

主权项

1. A method for decreasing sensitivity of astigmatic correction to errors of cylinder power selection and lens rotational alignment, comprising:
receiving a measure of astigmatism; receiving a selection of a toric lens to reduce the astigmatism; receiving a determination of a depth of focus extension for coupling with the selected toric lens; coupling the determined depth of focus extension and the selected toric lens; inserting the coupled depth of focus extension and the selected toric lens in a line of sight.
