The present invention relates to methods of implementing an optical element having a refraction modulating com-position. The methods include using a wavefront sensor to provide an optical measurement of the optical element. The present invention also relates to systems comprising an optical element having a refraction modulating composition and a wavefront sensor. An embodiment is described in which the optical element is an intraocular lens. Optical aberrations of the lens measured by the wavefront sensor are corrected by photo-polymerization of the refraction modulating composition which alters the refractive properties of the lens. Correction of lens refractive errors can be carried out after the lens has been implanted in the eye.
