Abstract: Scopes for viewing interior chambers of the eye include a refractive hydrogel polymer button formed by femtosecond laser micro-machining. The refractive button is sandwiched between two transparent plates and mounted on an ocular adapted to be placed directly on the cornea. A physician may look directly through the scope to see anatomical structures at very steep angles within the eye, such as to function as a gonioscope when viewing the anterior chamber angle. The scopes can be modified for viewing a variety of anatomical structures within the eye, and can also be used in conjunction with treatments such as by guiding injections or laser procedures. The refractive button has at least one region with a wavefront pattern of linear steps formed therein. Multiple regions with different wavefront patterns provide the physician with greater flexibility. The refractive button may be rotated relative to the ocular to further customize the image.
