An ophthalmic device is formed by additive fabrication, the optical device having optical surface with a surface roughness on the order of less than 10 microns. A method is provided for making an ophthalmic device including an optical surface having a surface roughness of less than 10 microns by depositing on a stage in a first relative position a first lamina of particulates having a size less than 10 microns and in select configurations less than two microns and certain configurations less than one micron, and, synergistically stimulating the first lamina of particulates to form a first solidified layer.

A surgical instrument having a cutting end which includes a pair of grooves to provide a structure having a pair of opposed flanges. The back of the surgical instrument has a back channel. A pair of cutting edges are provided on the surgical instrument. The cutting edges are generally offset and parallel with respect to each other. A method for forming a channel in a femoral condyle of a knee joint of a person, and a method for reconstructing an anterior cruciate ligament of a knee joint of a person. The methods comprise using the surgical instrument in an inside-out fashion, as opposed to an outside-in fashion, in order to cut a trough into a femoral condyle.
