A method for treating presbyopia by performing ablative photodecomposition of the corneal surface. The offset image of a variable aperture, such as a variable width slit and variable diameter iris diaphragm, is scanned in a preselected pattern to perform ablative sculpting of predetermined portions of a corneal surface. The scanning is performed to ablate an optical zone sized to match the patient pupil with a peripheral transition zone outside the pupil. The shape of the ablated optical zone is different from the shape of the final optical correction on the anterior surface of the cornea. The optical zone corrects for near-vision centrally and far-vision peripherally. A movable image displacement mechanism enables radial displacement and angular rotation of the profiled beam exiting from the variable aperture. The method enables wide area treatment with a laser having a narrower beam than the treatment area, and can be used in the treatment of many conditions in conjunction with presbyopia such as hyperopia, hyperopic astigmatism and irregular refractive aberrations.

This invention addresses the scalability problem of periodic “nanostructured” surface treatments such as those formed by interference lithography. A novel but simple method is described that achieves seamless stitching of nanostructure surface textures at the pattern exposure level. The described tiling approach will enable scaling up of coherent nanostructured surfaces to arbitrary area sizes. Such a large form factor nanotechnology will be essential for fabricating large aperture, coherent diffractive elements. Other applications include high performance, antiglare/antireflection and smudge resistant Motheye treatments for display products such as PDA's, laptop computers, large screen TV's, cockpit canopies, instrument panels, missile and targeting domes, and, more recently, “negative-index” surfaces. Although ideal for seamless stitching of nanometer scale patterns, the technology is broadly applicable to any situation where an arbitrarily large area needs to be seamlessly tiled with a smaller base pattern that has periodic overlap able boundaries.
