If you wish to discontinue your trial treatment we would advise you to do this in consultation with the LENS research team. However we’d still like to send you questionnaires to ensure the trial’s results are reliable. You are free to completely withdraw from the trial at any time in which case you will not receive any further questionnaires.

For women: Women who could become pregnant must continue to use effective methods of contraception for 7 days after stopping trial treatment (or the end of the study).
