OPHTEC's iris reconstruction implants are available in brown, green and blue. These colours have been carefully chosen to simulate the natural colouring of most eyes. 


1. The anterior segment reconstruction prostheses are only available in 3 standard colours and therefore OPHTEC cannot guarantee the perfect colour match with the fellow eye.
2. After implantation in the eye the colour of the prosthesis might look lighter.
3. For a better evaluation and choice of the colour match, we suggest to consult OPHTEC representatives.
