Abstract
This work analyzes the use of a single cubic phasemask as a solution to moderate astigmatism of different orientations and magnitudes. The experimental results with artificial eye show that a cubic phasemask of the type 7.07 µm×(Z₃³-Z₃⁻³) @ 5mm pupillary diameter, can be a solution to the astigmatism up to 3D with different orientations. The logMAR visual acuity obtained for all orientations is close to 0.05 for pupil sizes of 3 mm, 5 mm, 7 mm. These results are a good starting point for the development of contact lenses or intraocular lenses that do not require stabilization systems increasing tolerance to errors in the correction of the astigmatism.
