Letters: Material matters

We refer to the article entitled ‘Why are 1 day SiH lenses a good choice for my patients?’ published in Optician on November 6, 2020.

This is based on a publication that appeared in Contact Lens and Anterior Eye in June 2020.¹ We are pleased to see it has been revised to some degree following our letter to the editor of that journal² setting out our concerns, including that the conclusion of the paper was not supported by the selective body of evidence in the publication.

We still have significant concerns with this revised article. Fundamentally, we still fail to be convinced that the conclusion ‘for the vast majority of patients SiH 1 day CLs are most likely to result in long term successful wear’ is in any way justified by the evidence base cited. Perhaps a more apt title would have been ‘Why are 1 day lenses a good choice for my patients?’
