Bill Harvey: Living in the material world

Earlier this year, I attended a Coopervision roadshow featuring an excellent lecture from Professor Lyndon Jones (see Optician 03.05.19) that espoused the virtues of silicone hydrogel for daily disposable lenses. This was soon followed by an article offering a similar argument (Optician 05.07.19). This week, we publish an article (see page 24) outlining the evidence base in support of hydrogel material, including the latest references that support the view that there are good reasons for its continuing to be the most popular material for daily disposable lenses.

So, what should we do in practice? As always with such debates, there are arguments for each material and first choice should always be patient specific. I have a non-existent tear film and find it difficult to tolerate SiHy lenses for more than a few hours without comfort drops.
