Abstract:
1. A method for increasing the depth of focus of a patient, the method comprising: providing a corneal inlay comprising an aperture configured to transmit along an optical axis substantially all incident visible light and a portion configured to be substantially opaque to visible light and to surround at least a portion of the aperture, the corneal inlay comprising a plurality of randomly located nutrient flow paths in a central region of the substantially opaque portion, the nutrient flow paths having an average amount of open area per unit area in the central region and being randomly located and having a minimum wall thickness defined between adjacent nutrient flow paths, the substantially opaque portion of the corneal inlay further comprising an inner peripheral region between the central region and the aperture and an outer peripheral region between the central region and an outer edge of the inlay, the inner and outer regions having nutrient flow paths permitting some nutrient flow therethrough, at least one of the inner and outer regions having greater opacity due to a lower amount of open area per unit area; and inserting the corneal inlay into a cornea of an eye of the patient.
