Abstract
The wavefront aberrator is applicable to correct aberrations of the human eye. In one embodiment, the aberrator device comprises a pair of transparent lenses separated by a layer of curable resin comprising monomers and polymerization initiators. By controlling the extent of its curing, this monomer layer provides an adjustable index of refraction profile across the layer. Curing of the resin may be made by exposure to light, such as ultraviolet light. By controlling the extent of light exposure across the surface of the curable resin, for example, a particular and unique refractive index profile can be produced.
