ClarVista has developed the Harmoni modular intra-ocular lens system. The two piece Harmoni IOL system enables vision optimization through better initial positioning of the lens, and the safe and easy exchange of the lens optic when required. Initial studies also indicate that the risk of development of secondary cataracts is significantly reduced by the Harmoni system. 

ClarVista has been acquired by Alcon.
