Abstract
An ophthalmic device that includes a mask configured to be implanted posterior of the cornea. The mask is configured to increase the depth of focus of the patient. The mask includes an aperture configured to transmit along an optical axis substantially all incident light and a substantially opaque portion surrounding at least a portion of the aperture. The ophthalmic device can further include a plurality of light transmission structures configured to allow some light to pass through the substantially opaque portion. The light transmission structures are configured to minimize generation of visible artifacts due to the transmission of light through the light transmission structures.
