If you use izanagi and then awaken rinnegan or transplant rinnegan in your blind eye your eyesight will be restored. If you awakened you rinnegan then you can access your sharingan abilities, though if you transplant it you can use only the rinnegan abilities. Though I'm not sure if you use izanagi after you awaken you rinnegan, whether you lose your eyesight or just your sharingan and keep the rinnegan.
